However, the general configuration update method is for developers to manually change the configuration of the application in the configuration center. Especially when multiple applications share a configuration center, every time the configuration of an application needs to be changed, the configuration personnel have to enter the configuration center to make manual adjustments. This process greatly increases the maintenance cost. Summary of the invention

DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail below with reference to the accompanying drawings and examples.

[0011] It should be noted that the term "and / or" is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of types. For example, at least one of A, B, and C can represent any one or more elements selected from the set consisting of A, B, and C.

[0012] See also Figure 1 , Figure 1 is a flow chart of an embodiment of a configuration update method provided by the present application. It should be noted that if there are substantially the same results, this embodiment is not based on Figure 1 The process sequence shown is limited. Figure 1 As shown, this embodiment includes: Step S11: Obtain the local configuration of the application service.

[0013] The local configuration of an application service in this article refers to the configuration information used to specify the behavior, parameters, and properties of an application service when the application service is running in a local environment (such as a developer's personal computer or a local server, etc.). The local configuration in this article can exist in the form of a configuration set to make configuration management more modular and easier to manage. Among them, a configuration set refers to a collection of related or unrelated configuration items. A configuration set can contain configuration items related to data sources, thread pools, schedule levels, etc.

[0014] The configuration information in these local configurations can usually be stored in local files (target files), environment variables, databases, or other external storage systems. For example, the local configuration corresponding to the application service can be obtained from a local file. In a specific embodiment, obtaining the local configuration of the application service includes: obtaining a target file whose file identifier is the service identifier of the application service. Reading the local configuration of the application service from the target file. For example, using the provided file operation interface, traverse the specified directory and its subdirectories. During the traversal process, check whether the file identifier of each file matches the service identifier of the application service. Once a matching file is found, use the file as the target file, open the target file and read its content. According to the format of the file (such as INI, JSON, YAML, properties, etc.), use the corresponding parsing method to extract the local configuration.

[0015] In this embodiment, the file identifier corresponding to the target file can be used to quickly locate the target file containing the configuration required by the application service from among many files, thereby ensuring accurate acquisition and efficient management of configuration information. In a specific embodiment, the target file is stored in the file directory of the configuration center of the application service.

[0016] The service identifier of the application service also has an identification function. The service identifier can be used as a unique identity mark of the application service, and can indicate the specific application service corresponding to the identifier. The above identification mechanism can ensure that when facing multiple target files or multiple application services, they can be accurately identified and distinguished. Among them, the service identifier can be obtained by splicing the unique identifier. In a specific implementation, the service identifier of the application service is obtained by splicing the namespace and service name of the application service.

[0017] Take the confirmation of the target file as an example. The target file is saved in the / resource / nacos / directory of the application service, where this directory is the file directory for the configuration center. The service name of the application service is demo-test, and the namespace is prod, then the corresponding service identifier is demo-test-prod.properties. Among them, ".properties" is a file extension, which is usually used to represent a properties file. Find the file identified as demo-test-prod.properties in the / resource / nacos / directory as the corresponding target file.

[0018] It should be noted that the local configuration obtained in this article refers to the latest configuration saved in the target file. In one embodiment, before obtaining the local configuration of the application service, at least one of the following steps is also included: in response to the user's creation operation, create and save the local configuration of the application service. In response to the user's modification operation, modify the saved local configuration of the application service. After performing at least one of the above steps, the latest configuration saved in the target file is obtained as the local configuration for use in subsequent operations.

[0019] Step S12: Obtain the server configuration of the application service from the configuration center.

[0020] The configuration center in this article refers to a common component in the microservice architecture, which is mainly used to centrally manage the configuration information of the application. The configuration center is usually used to pull configuration information from the configuration center when the application starts to start the application service. Among them, the configuration center includes Spring Cloud Config, Nacos, Zookeeper, Apollo, etc. In one embodiment, the configuration center is Nacos.

[0021] The server configuration can be obtained through a variety of methods such as preset interfaces, SDKs, consoles, monitoring configuration change events, and integrated frameworks. In one embodiment, obtaining the server configuration of the application service from the configuration center includes: obtaining the server configuration corresponding to the service identifier of the application service from the configuration center through a preset interface. For example, in the case where the configuration center is Nacos, the preset interface provided by Nacos allows the corresponding server configuration information to be obtained through an HTTP request. A GET request can be sent to a specific URL of the Nacos server with necessary request parameters (such as a service identifier) ​​to obtain the corresponding server configuration.

[0022] It should be noted that the server configuration obtained in this article refers to the latest configuration saved in the configuration center. For specific instructions, please refer to the relevant description in step S11.

[0023] Step S13: Merge the local configuration and the server configuration to obtain the current configuration of the application service.

[0024] The merging of local configuration and server configuration in this article can effectively integrate modifications made to both local configuration and server configuration. Modifications in local configuration are conducive to local maintenance. Developers can add and delete configuration items in local configuration according to actual needs. After the configuration items of the local configuration are updated, the local configuration and the server configuration are merged, and the current configuration is obtained and sent to the configuration center. There is no need for configuration personnel to frequently synchronize or update with the configuration center, or even to enter the configuration center for manual updates. Secondly, the server configuration is also flexible. In some scenarios, only some configuration items may need to be fine-tuned. At this time, they can be modified directly in the server configuration without rewriting or redeploying the entire configuration.

[0025] In one embodiment, the local configuration and the server configuration respectively include configuration information of at least one configuration item; the current configuration includes at least one of the configuration information of the common configuration items in the server configuration and the configuration information of the first unique configuration item in the local configuration, the common configuration item is a configuration item that exists in both the server configuration and the local configuration, and the first unique configuration item is a configuration item that exists in the local configuration but not in the server configuration.

[0026] In a specific implementation, merging the local configuration and the server configuration to obtain the current configuration of the application service includes: deleting the configuration information of the common configuration item in the local configuration to obtain a first configuration to be merged; and deleting the configuration information of the second unique configuration item in the server configuration to obtain a second configuration to be merged, where the second unique configuration item is a configuration item that exists in the server configuration but does not exist in the local configuration; and combining the first configuration to be merged and the second configuration to be merged to obtain the current configuration.

[0027] In this embodiment, the local configuration and the server configuration each contain configuration information of a configuration item. In a specific embodiment, the configuration item and the corresponding configuration information are recorded in the local configuration and the server configuration in a key-value pair. For example, a configuration item can be a specific configurable key and its value, usually in the form of KEY=VALUE (KEY is a configurable key, and VALUE is its corresponding value). For example, the log output level (logLevel=INFO|WARN|ERROR) used to configure the system is a configuration item.

[0028] Combination Figure 2 To illustrate with an example, Figure 2 This is a configuration merging diagram of the configuration update method provided by the present application. The local configuration is K1=V11, K4=V4, and the server configuration is K1=V1, K2=V2. Among them, the first unique configuration item unique to the local configuration is K4=V4, the second unique configuration item unique to the server configuration is K2=V2, the configuration information of the common configuration items in the local configuration is K1=V11, and the configuration information of the common configuration items in the server configuration is K1=V1. The configuration information K1=V11 of the common configuration items in the local configuration is deleted to obtain the first configuration to be merged K4=V4. The configuration information K2=V2 of the second unique configuration item in the server configuration is deleted to obtain the second configuration to be merged K1=V1. The first configuration to be merged K4=V4 and the second configuration to be merged K1=V1 are combined to obtain the current configuration K1=V1, K4=V4.

[0029] Step S14: Send the current configuration to the configuration center, so that the configuration center updates the server configuration of the application service to the current configuration.

[0030] In one implementation, the steps of obtaining the local configuration of the application service to sending the current configuration to the configuration center are performed when the application service is started and the local configuration is created or modified.

[0031] In another embodiment, after sending the current configuration to the configuration center so that the configuration center updates the server configuration of the application service to the current configuration, at least one of the following steps is further included: receiving a configuration update notification from the configuration center, the configuration update notification being sent after the configuration center updates the server configuration of the application service. In response to the application service startup, the current server configuration of the application service is obtained from the configuration center, and the startup of the application service is completed based on the current server configuration of the application service.

[0032] Combination Figure 3 To illustrate with an example, Figure 3It is a schematic diagram of the overall design architecture of the configuration update method provided by the present application. Among them, the configuration center includes a configuration center server and a configuration center client. The configuration publishing and updating module in the application service is used to obtain the local configuration and the server configuration, and merge the local configuration with the server configuration to generate the corresponding current configuration, and publish the current configuration to the configuration center server. When the application service is started and the local configuration is created or modified, step S31 is executed for the configuration publishing and updating module to obtain the local configuration and the server configuration to obtain the corresponding current configuration, and publish the current configuration to the configuration center server. After the configuration center server updates the server configuration of the application service to the current configuration, it also includes at least one of the following steps: step S32 The configuration center client obtains the current configuration from the configuration center server to complete the startup of the application service. Step S33 The configuration center client receives the configuration update notification from the configuration center server. When the server configuration is modified, at least one of step S32 and step S33 is executed.

[0033] See also Figure 4 , Figure 4 1 is a flow chart of a specific embodiment of the configuration update method provided by the present application. Among them, the configuration center of this embodiment is exemplarily Nacos. Figure 4 As shown, the configuration update method provided in this embodiment may include the following steps: Step S41: Read the namespace and service space of the application service and obtain the corresponding service identifier. Step S42: Determine the target file corresponding to the file identifier that matches the service identifier and obtain the local configuration corresponding to the application service in the target text. Step S43: Obtain the server configuration of the application service on the Nacos server. After obtaining the local configuration in step S42 and the server configuration in step S43, execute step S44: Merge the local configuration and the server configuration to obtain the current configuration. Step S45: Publish the current configuration to the Nacos server.
