[0053] Exemplary embodiments of the present application are described below with reference to the accompanying drawings, which include various details of the embodiments in order to assist in understanding them. These should be considered as merely exemplary, and therefore, it will be recognized by those of ordinary skill that various modifications and changes in the embodiments described herein can be made without departing from the scope and spirit of the application. Also, for the sake of brevity and clarity, descriptions of well-known functions and constructions are omitted herein. The acquisition, storage, use, processing, etc. of data in the technical solutions of the present application comply with relevant provisions of national laws and regulations.

[0054] In order to solve the problem that the execution order of the service cannot be guaranteed, and the business logic error is prone to occur, the technical solution in the embodiment of the application can be used.

[0055] Referring to Figure 1 , Figure 1 is a main flow diagram of a method for calling a business service according to an embodiment of the application, and a microservice is called through a service combination model to process an execution request. Figure 1 Specifically, the method includes the following steps.

[0056] S101, a service combination model of a business service is constructed based on a plurality of microservices involved in the business service, a business relationship between the plurality of microservices, and a calling state of the plurality of microservices, and the service combination model is stored in a configuration center.

[0057] The microservice is a software development technology, and is a variant of a service-oriented architecture (SOA) architecture style, which constructs an application as a collection of loosely coupled services. The microservice refers to developing a single small but business function service, and each service has its own processing and lightweight communication mechanism, and can be deployed on a single or multiple servers.

[0058] In the embodiment of the application, the business service is executed through a plurality of microservices. As an example, the business service includes purchasing a commodity or refunding a commodity. It can be understood that a plurality of microservices are called to implement the business service. The plurality of microservices have a business relationship. For example, the business service includes purchasing a commodity, and involves a shopping cart microservice and a commodity microservice. The relationship between the shopping cart microservice and the commodity microservice is the business relationship.

[0059] Further, a service combination model of a business service is constructed based on a plurality of microservices involved in the business service, a business relationship between the plurality of microservices, and a calling state of the plurality of microservices, and the service combination model is stored in a configuration center. The calling state of the microservice is the state of a microservice component that executes the microservice. As an example, the calling state of the microservice includes callable and prohibited calling. In the case that the calling state of the microservice is callable, the microservice component is used to implement the execution of the microservice. In the case that the calling state of the microservice is prohibited calling, it indicates that the microservice component is unavailable, and therefore the microservice cannot be executed.

[0060] Each microservice represents a specific java microservice. In an embodiment of the application, the configuration center includes a zookeeper.

[0061] Referring to Figure 2 that is 200, Figure 2 is a flow diagram of constructing a service combination model of a business service and storing the service combination model in a configuration center according to an embodiment of the application. Specifically, the method includes the following steps.

[0062] S201, screening a plurality of microservices involved in the business service according to the business logic of the business service.

[0063] Each microservice is an independent node responsible for processing a specific business function or data. The execution of the business service involves multiple microservices. The plurality of microservices involved in the business service can be screened according to the business logic of the business service.

[0064] As an example, the business service includes purchasing goods, and the plurality of microservices involved in the business service is screened according to the business logic of the business service: user microservice, shopping cart microservice, goods microservice, order microservice, and payment microservice.

[0065] S202, determining the calling order of the microservices based on the business logic order in the business relationship between the plurality of microservices, and determining the dependency relationship and dependency condition between the microservices according to the data flow of the microservices in the business relationship between the plurality of microservices.

[0066] The business relationship of the business service includes the business logic order and the data flow of the microservices. The business logic order is the execution order of the microservices. The data flow of the microservices is the data sequence from one microservice to another microservice in the data processing process.

[0067] In an embodiment of the present application, the calling order of the microservices is determined based on the business logic order in the business relationship between the plurality of microservices. As an example, the business logic order in the business relationship between the plurality of microservices includes: order microservice and payment microservice. The calling order of the microservices is determined to include: executing the order microservice first, and then executing the payment microservice.

[0068] In an embodiment of the present application, the dependency relationship and dependency condition between the microservices are determined according to the data flow of the microservices in the business relationship between the plurality of microservices. As an example, the user microservice and the order microservice have a dependency relationship and a dependency condition; the goods microservice and the order microservice have a dependency relationship and a dependency condition.

[0069] S203, establishing a service combination model according to the calling order of the microservices, the dependency relationship and dependency condition between the microservices, the calling state of the plurality of microservices, the input parameters of the microservices, and the output parameters of the microservices, and storing the service combination model to the configuration center based on the business identifier of the business service.

[0070] After the calling order of the microservices is established, the output parameters of the previous microservice are the input parameters of the next microservice, and then the service combination model is established according to the calling order of the microservices, the dependency relationship and dependency condition between the microservices, the calling state of the plurality of microservices, the input parameters of the microservices, and the output parameters of the microservices.

[0071] It is considered that each microservice has a corresponding calling state. Therefore, the calling state of the microservice also needs to be considered in the process of establishing the service combination model.

[0072] In the case that the calling state of the microservice includes callable, the service combination model can be established according to the calling sequence of the microservice, the dependency relationship and the dependency condition between the microservices, the calling state of the multiple microservices, the input parameter of the microservice and the output parameter of the microservice.

[0073] In the case that the calling state of the microservice includes prohibited calling, the callable microservice that replaces the prohibited calling microservice can be filtered out according to the business logic of the business service. Then, the service combination model can be established according to the calling sequence of the callable microservice, the dependency relationship and the dependency condition between the callable microservices, the calling state of the callable microservice, the input parameter of the callable microservice and the output parameter of the callable microservice.

[0074] In the case that the calling state of the microservice includes prohibited calling, the callable microservice that replaces the prohibited calling microservice is not filtered out according to the business logic of the business service. Then, considering that the calling state of the microservice will be updated, the service combination model can be established according to the calling sequence of the microservice, the dependency relationship and the dependency condition between the microservices, the calling state of the multiple microservices, the input parameter of the microservice and the output parameter of the microservice. After obtaining the service combination model, the calling state of the prohibited calling microservice needs to be updated to ensure the use of the service combination model.

[0075] The service combination model corresponds to the business service. That is, different business services correspond to different service combination models. The business service is the same, and the service combination model is the same. For the same business service, the same service combination model can be used, and it is not necessary to repeatedly establish the service combination model, thereby improving the calling accuracy of the business service and accelerating the calling speed of the microservice.

[0076] In the embodiment of the application, the service combination model is stored in the configuration center based on the business identifier of the business service. In this way, the service combination model can be obtained in the configuration center based on the business identifier of the business service.

[0077] In the embodiment of the application, Figure 2 In the embodiment of the application, the corresponding service combination model is established for the business service, thereby being capable of accelerating the calling accuracy and speed of the microservice.

[0078] Referring to Figure 3 i.e. 300, Figure 3is a schematic diagram of calling microservices for purchasing goods according to an embodiment of the present application. Specifically, when a user finishes shopping and prepares to pay, the user microservice, the shopping cart microservice, the goods microservice, the order microservice and the payment microservice are called. The calling states of the above microservices are all: callable. The role of each microservice is explained below.

[0079] The user microservice: verifies the identity and authority of the user.

[0080] The shopping cart microservice: obtains the shopping cart information of the user, including the list of goods and the quantity.

[0081] The goods microservice: verifies whether the goods in the shopping cart are still available, and obtains the latest goods information.

[0082] The order microservice: creates an order according to the shopping cart information, and sets an initial state. As an example, the initial state includes: to be paid.

[0083] The payment microservice: handles the payment logic, interacts with the third-party payment platform, and completes the payment process.

[0084] After the above microservices are executed in sequence, the payment is successful, the order state is updated to "paid", and the subsequent logistics or delivery process is triggered.

[0085] Referring to Figure 4 that is 400, Figure 4 is a schematic diagram of the dependency relationship between microservices according to an embodiment of the present application.

[0086] The order microservice depends on the user microservice to verify the user identity. Both the order microservice and the shopping cart microservice depend on the goods microservice to obtain and verify the goods information. The payment microservice can be independent of other microservices, but the payment microservice needs to interact with the order microservice to confirm the payment state and update the order. The shopping cart microservice depends on the user microservice to manage the shopping cart of the user.

[0087] In an embodiment of the present application, as the microservices in the business service are adjusted, the service composition model of the business service also needs to be adjusted. Specifically, the service composition model of the business service is updated according to the adjusted microservices of the business service and the business relationship between the adjusted microservices, and the service composition model of the business service of the configuration center is replaced by the updated service composition model of the business service.

[0088] In this way, the latest service composition model corresponding to the business service is stored in the configuration center. By updating the service composition model, the adjustment of the microservices is applicable.

[0089] S102, in response to the execution request of the business service, after the execution request of the business service is authenticated, the service combination model is obtained from the configuration center based on the business identifier of the business service, and the service list data of the business service is generated by combining the execution request of the business service and analyzing the service combination model.

[0090] The user sends an execution request of a business service for executing the business service. In order to improve the effectiveness of calling the business service, it is necessary to authenticate the execution request of the business service. After the execution request of the business service is authenticated, in response to the execution request of the business service, the service combination model is obtained from the configuration center based on the business identifier of the business service. The service list data of the business service is generated by combining the execution request of the business service and analyzing the service combination model. The service list data is an instantiation of the service combination model.

[0091] Referring to Figure 5 That is 500, Figure 5 is a flowchart of generating service list data of a business service by combining an execution request of the business service and analyzing a service combination model according to an embodiment of the application. Specifically, it includes the following steps.

[0092] S501, in response to the execution request of the business service, after the execution request of the business service is authenticated based on the business identifier of the business service, the service combination model is obtained from the configuration center based on the business identifier of the business service, and the service list data of the business service is generated by combining the execution request of the business service and analyzing the service combination model.

[0093] The business identifier of the business service is obtained from the execution request of the business service. The execution request of the business service is authenticated according to the business identifier of the business service. As an example, the business identifier of the business service has the permission to call the service combination model, then the execution request of the business service is authenticated; the business identifier of the business service does not have the permission to call the service combination model, then the execution request of the business service is not authenticated. For example, the authentication of the execution request of the business service is realized by white list.

[0094] Further, the service combination model is obtained from the configuration center based on the business identifier of the business service. As an example, the service combination model is stored in the configuration center in the form of a table.

[0095] The service combination model is analyzed, and the microservices of the business service, the calling sequence of the microservices, the calling state of the microservices, the dependency relationship of the microservices and the dependency conditions of the microservices are obtained. Among them, the calling sequence of the microservices, the dependency relationship of the microservices and the dependency conditions of the microservices belong to the cooperation mechanism among the microservices.

[0096] The calling state of the microservice can be learned based on the identification of the microservice of the business service.

[0097] S502, according to the execution request of the business service, the dependency relationship of the microservice, the dependency condition of the microservice and the calling state of the microservice, the execution microservice of the business service is screened out.

[0098] In the embodiments of the present application, the microservice can be divided into execution microservice and dependent microservice. The execution microservice is the microservice that processes the execution request. The dependent microservice is the microservice that provides data.

[0099] As an example, the business service involves user microservice, shopping cart microservice, commodity microservice, order microservice and payment microservice. The execution microservice includes: shopping cart microservice, order microservice and payment microservice. The dependent microservice includes user microservice and commodity microservice.

[0100] Specifically, according to the execution request of the business service, the dependency relationship of the microservice, the dependency condition of the microservice and the calling state of the microservice, the execution microservice of the business service is screened out. As an example, the calling state of the microservice of the business service is determined to include: callable. The microservice that processes the execution request is taken as the execution microservice. The microservice that has dependency relationship and dependency condition with the execution microservice is taken as the dependent microservice. As another example, the calling state of the microservice of the business service is determined to include: forbidden calling, which means that the microservice of the business service is unavailable, and the calling of the business service is stopped. In order to guarantee the calling of the business service, the calling state of the microservice can be updated by a preset period when the calling state of the microservice of the business service is determined to include: forbidden calling. When the calling state of the microservice of the business service is determined to include: callable, the microservice that processes the execution request is taken as the execution microservice. The microservice that has dependency relationship and dependency condition with the execution microservice is taken as the dependent microservice.

[0101] S503, according to the calling sequence of the execution microservice, the service list data of the business service is constructed.

[0102] Based on the calling sequence of the microservice, the calling sequence of the execution microservice is further obtained. According to the calling sequence of the execution microservice, the service list data of the business service is constructed. As an example, according to the calling sequence of the execution microservice, the instantiation code block of the execution microservice is executed, and the service list data of the business service is generated. As an example, the service list data of the business service is json format data.

[0103] The service list data of the business service can realize the instantiation of the execution request of the business service. The service list data is the running state data, which clearly shows the execution sequence of each microservice. Through the service list data, the calling process of the microservice can be accurately controlled.

[0104] In Figure 5 In an embodiment of the application, the instantiation of the execution request of the business service is implemented by using the service combination model.

[0105] Referring to Figure 6 That is, 600, Figure 6 is a flowchart for constructing the service list data of the business service according to the calling order of the microservices in the execution of the microservices according to an embodiment of the application. Specifically, the following steps are included.

[0106] S601, according to the execution request of the business service, the execution microservices are divided into multiple business execution groups.

[0107] In an embodiment of the application, considering that the number of microservices involved in the business service is large, in order to quickly establish the data of the service list data, the execution microservices can be divided into multiple business execution groups according to the execution request of the business service.

[0108] As an example, according to the process of the execution request of the business service, the execution microservices are divided into multiple business execution groups. For example, the microservices in the first process are divided into a first business execution group; the microservices in the second process are divided into a second business execution group; and the microservices in the third process are divided into a third business execution group.

[0109] S602, according to the execution microservices in the business execution group and the calling order of the execution microservices, the service list data of the business execution group is constructed.

[0110] For each business execution group, according to the execution microservices in the business execution group and the calling order of the execution microservices, the service list data of the business execution group is constructed. That is, the corresponding service list data is established for each business execution group.

[0111] S603, according to the calling order of the microservices and the service list data of the business execution group, the service list data of the business service is established.

[0112] According to the calling order of the microservices, the order of the service list data of the business execution group can be determined. Further, according to the order of the service list data of the execution group and the service list data of the business execution group, the service list data of the business service is established.

[0113] In Figure 6 In an embodiment of the application, the service list data of the business service is established by grouping, and then the business service is executed by the service list data of multiple business execution groups.

[0114] S103, according to the service list data of the business service, the execution order of the microservice is known and the microservice is called in turn according to the execution order of the microservice, and the execution state of the microservice is adjusted to process the execution request of the business service.

[0115] After obtaining the service list data of the business service, the engine knows the execution order of the microservice and calls the microservice in turn according to the execution order of the microservice, and adjusts the execution state of the microservice to process the execution request of the business service. That is, the engine processes the execution request of the business service according to the service list data of the business service.

[0116] Referring to Figure 7 That is 700, Figure 7 is a flowchart of adjusting the execution state of the microservice to process the execution request of the business service according to an embodiment of the application. Specifically, it includes the following steps.

[0117] S701, based on the service list data of the business service, the execution order of the microservice and the dependency condition of the microservice are obtained, and the execution state of the microservice is adjusted according to the dependency condition of the microservice.

[0118] In an embodiment of the application, the engine obtains the execution order of the microservice and the dependency condition of the microservice based on the service list data of the business service, and adjusts the execution state of the microservice according to the dependency condition of the microservice.

[0119] The dependency condition of the microservice is the prerequisite for the execution of the microservice. As an example, the dependency condition of the order microservice is to obtain user information from the user microservice and obtain commodity information from the commodity microservice.

[0120] In an embodiment of the application, the execution state of the microservice includes ready, running, blocking and failure. In the case of ready and running, it means that the microservice processes the execution request normally; in the case of blocking and failure, it means that the microservice processes the execution request abnormally.

[0121] Based on the service list data of the business service, the execution order of the microservice and the dependency condition of the microservice are obtained, and the execution state of the microservice can be adjusted according to the dependency condition of the microservice.

[0122] As an example, the dependency condition of the microservice is satisfied and the execution request has not been processed, and the execution state of the microservice is adjusted to: ready.

[0123] The dependency condition of the microservice is satisfied and the execution request is being processed, and the execution state of the microservice is adjusted to: running.

[0124] The dependency condition of the microservice is not satisfied or the execution request is processed once abnormally, and the execution state of the microservice is adjusted to: blocking.

[0125] If the dependency condition of the microservice is not met or the processing execution request multiple times is abnormal, the execution state of the microservice is adjusted to: failure.

[0126] S702, according to the execution order of the microservice and the execution state of the microservice, the microservice is called to process the execution request of the business service.

[0127] Each microservice has an execution order and an execution state, and the engine can call the microservice to process the execution request of the business service according to the execution order of the microservice and the execution state of the microservice.

[0128] Referring to Figure 8 That is 800, Figure 8 is a flowchart of calling the blocked or failed microservice again according to the exception handling operation according to an embodiment of the application. Specifically, the following steps are included.

[0129] S801, the execution state of the microservice includes blocking or failure, and based on the blocked or failed microservice and the execution request, the configuration center is queried to obtain the exception handling operation.

[0130] In the case where the execution state of the microservice includes ready or running, the microservice can be directly called to process the execution request of the business service.

[0131] In the case where the execution state of the microservice includes blocking or failure, it means that the microservice cannot normally process the execution request of the business service, and the exception handling operation needs to be obtained from the configuration center. The exception handling operation is preset in the configuration center based on the identification of the microservice.

[0132] Specifically, in the case where the execution state of the microservice includes blocking or failure, the configuration center is queried based on the blocked or failed microservice and the execution request to obtain the exception handling operation.

[0133] S802, the blocked or failed microservice is called again according to the exception handling operation to continue processing the execution request of the business service.

[0134] After obtaining the exception handling operation from the configuration center, the blocked or failed microservice is called again according to the exception handling operation to continue processing the execution request of the business service.

[0135] In an embodiment of the application, the exception handling operation includes: a retry strategy and a skip failed microservice strategy. As an example, in the application scenario of online payment, the retry strategy will be executed due to the network fluctuation leading to the first call failure.

[0136] Retry strategy: preset maximum retry number and retry time interval. When the microservice call fails, check whether the retry number has reached the maximum retry number. If the maximum retry number is not reached, wait for the retry time interval and retry again. If the microservice call still fails after the maximum retry number is reached, the skip strategy is executed.

[0137] Skip strategy: identify microservices that can be skipped in the service list data. In the case of calling microservices that can be skipped, if the call to the microservice fails, record the failure information, but do not interrupt the execution request for processing the business service in the next microservice.

[0138] In the above embodiment of the application, the service combination model of the business service is constructed based on the multiple microservices involved in the business service, the business relationship between the multiple microservices, and the call state of the multiple microservices, and the service combination model is stored in the configuration center. In response to the execution request of the business service, after the execution request of the business service is authenticated, the service combination model is obtained from the configuration center based on the business identifier of the business service, and the service list data of the business service is generated by parsing the service combination model in combination with the execution request of the business service. According to the service list data of the business service, the execution order of the microservices is obtained, and the microservices are called in sequence according to the execution order of the microservices, and the execution state of the microservices is adjusted to process the execution request of the business service. The service combination model of the business service can preset the microservices for implementing the business service, so as to reduce the business logic error and avoid service call failure or performance decline.
