Description

Technical Field

[0001] The present invention relates to the technical field of software product development based on underlying databases, and in particular to a microservice implementation method and system that supports rapid switching of underlying databases. Background Art

[0002] With the development of software development and database technology, microservice development based on the underlying database has become the main theme of software development. The current database-based microservice development method has the following characteristics:

[0003] The business logic layer and data service layer codes are in the same microservice, and the backend service is usually provided by a microservice;

[0004] There is no clear boundary between the business logic layer code and the data service layer code, and they are intertwined. There is no standardized definition of the data service interface called by the business logic layer;

[0005] There is only one service process in the backend, and the data service layer can only establish a connection with one database through the connection pool. It is impossible to obtain data from multiple source databases.

[0006] The above characteristics lead to the following problems:

[0007] 1. The code is mixed, difficult to sort out, and lacks hierarchical logic.

[0008] 2. The development workload of adapting to different underlying databases is large.

[0009] 3. The testing cycle is long, and the function and performance testing of the data interface needs to start from the entire platform function.

[0010] 4. It is unable to meet the needs of various underlying databases to support microservices.

[0011] In software projects, due to factors such as customer procurement and policies, the software platform sometimes needs to urgently switch to adapt to the underlying database. In the software development process, simple adaptation of the underlying database becomes an urgent need. Summary of the invention

[0012] The technical task of the present invention is to address the above shortcomings and provide a microservice implementation method and system that supports rapid switching of the underlying database, which can simplify the workload, optimize code logic, and improve development efficiency and product reliability during the background service development process of adapting and switching the underlying database of software products.

[0013] The technical solution adopted by the present invention to solve the technical problem is:

[0014] A microservice implementation method that supports fast switching of underlying databases, which divides the backend logic code into microservice layers, a business logic layer and a data service layer; the code involving the platform business logic, the data service interface and the client connection part are classified into the business logic layer microservice, and the data service implementation, the data access layer and the driver part are classified into the data service layer microservice; developers develop microservices of the data service layer by adapting the data interface standard of the business logic layer, so as to realize the software product support for the switching of the underlying database.

[0015] This method splits the backend service code of the software into two layers, the upper layer microservice performs business logic processing and data interface definition, and the lower layer microservice is responsible for connecting to the underlying database and implementing data services. In the case of switching the underlying database, it is only necessary to complete the development and adaptation of the lower layer microservice, and then replace and deploy the lower layer microservice. This method divides the backend service architecture of the software into layers and refines it, and standardizes the definition of the data interface layer. The lower layer microservice will not involve changes to the upper layer business logic code during the adaptation and development process, and the microservice development of the data service layer is directly carried out according to the interface and interface function description. This method is mainly used to simplify the workload of software products in the background service development process of adapting and switching the underlying database, optimizing code logic, and improving development efficiency and product reliability.

[0016] Furthermore, the method is applicable to the development of back-end microservices for software products using a B / S or C / S architecture. The microservice layered architecture can support Web (B / S) or App (C / S) applications and is not limited to the separation of the front-end and back-end.

[0017] Furthermore, the business logic layer includes: a control layer, a service layer, a data interface layer, and a client tool; the business logic layer provides interactive interface services to the front end of the B / S or C / S;

[0018] The control layer is mainly responsible for the interface definition with the interaction layer; the data interface layer is responsible for the interface definition with the data service layer; the service layer is responsible for business logic processing;

[0019] The interface between the business logic layer and the interaction layer adopts the form of REST interface;

[0020] The business logic layer and the data service layer communicate through RPC or REST interfaces, and use accounts and encrypted channels for security protection.

[0021] Furthermore, the data service layer implements the data interface definition of the business logic layer and provides data interface services for the business logic layer; the data service layer structure includes: server tools, service layer, driver layer, and may include a persistence layer;

[0022] The server-side tools provide data service interfaces and security authentication interfaces; the service layer provides basic services and logical services.

[0023] Furthermore, under the premise of implementing the standard interface of the business logic layer in the data service layer, the underlying database can be switched by deploying different data service layer microservices;

[0024] And under the premise of meeting the data interface definition of the business logic layer, the database table structure can be adjusted and optimized as long as it can meet the data interface service implementation.

[0025] Furthermore, a single business logic layer microservice can call multiple data service layer microservices;

[0026] A single data service layer microservice can provide data services to multiple business logic layer microservices that define interfaces;

[0027] That is, multiple data service layer microservices can support the same business logic layer service call; a single data service layer microservice can support multiple business logic layer microservice calls;

[0028] The same platform can be supported by multiple databases of the same type, or a specified database type can be used.

[0029] Furthermore, the implementation process of this method is as follows:

[0030] S1. The front end performs data query operations and accesses the query interface of the business logic layer;

[0031] S2, the business logic layer performs logic processing and calls the data interface layer interface;

[0032] S3, the data interface layer requests the data service of the interface from the data service layer through the RPC\REST client;

[0033] S4, the data service layer receives the data service request from the business logic layer through the server;

[0034] S5. The data service layer queries the database through the driver program and provides services to the business logic layer after service processing.

[0035] The present invention also claims a microservice implementation system that supports fast switching of underlying databases, including: a front-end interaction layer module, a business logic layer module and a data service layer module.

[0036] The front-end interaction layer module includes a front-end UI and an interaction layer;

[0037] The business logic layer module includes a control layer, a service layer, a data interface layer and a client tool;

[0038] The data service layer module includes a server-side tool, a service layer and a driver layer;

[0039] The system realizes adaptation and switching of the underlying database and provides data services through the above-mentioned microservice implementation method that supports rapid switching of the underlying database.

[0040] The present invention also claims a microservice implementation device that supports fast switching of underlying databases, comprising: at least one memory and at least one processor;

[0041] The at least one memory is used to store a machine-readable program;

[0049] The embodiment of the present invention provides a microservice implementation method that supports fast switching of underlying databases. The backend logic code is divided into microservice layers, which are divided into a business logic layer and a data service layer. The code, data service interface and client connection part related to the platform business logic are classified into the business logic layer microservice, and the data service implementation, data access layer and driver part are classified into the data service layer microservice. Developers develop microservices for the data service layer by adapting the business logic layer data interface standard to solve the need for software products to support the switching of underlying databases. The overall architecture diagram of this method is shown in the figure below. Figure 1 shown.

[0050] This method is suitable for the development of back-end microservices for software products using B / S or C / S architecture, that is, the microservice layered architecture can support Web (B / S) or App (C / S) applications, and is not limited to the separation of front-end and back-end.

[0051] The business logic layer includes: a control layer, a service layer, a data interface layer, and a client tool; the business logic layer provides interactive interface services to the front end of the B / S or C / S.

[0052] The control layer is mainly responsible for interface definition with the interaction layer; the data interface layer is responsible for interface definition with the data service layer; and the service layer is responsible for business logic processing.

[0053] The interface between the business logic layer and the interaction layer adopts the form of REST interface;

[0054] The business logic layer and the data service layer communicate through RPC or REST interfaces, and use accounts and encrypted channels for security protection.

[0055] The data service layer implements the data interface definition of the business logic layer and provides data interface services for the business logic layer; the data service layer structure includes: server-side tools, service layer, persistence layer (optional), and driver layer.

[0056] The server-side tools provide data service interfaces and security authentication interfaces; the service layer provides basic services and logical services.

[0058] And under the premise of meeting the data interface definition of the business logic layer, the database table structure can be adjusted and optimized as long as it can meet the data interface service implementation.

[0059] For this layered microservice architecture, a single business logic layer microservice can call multiple data service layer microservices; a single data service layer microservice can provide data services to multiple business logic layer microservices that define interfaces. That is, multiple data service layer microservices can support the same business logic layer service call; a single data service layer microservice can support multiple business logic layer microservice calls.

[0060] The same platform can be supported by multiple databases of the same type, or a specified database type can be used.

[0065] S4, the data service layer receives the data service request from the business logic layer through the server;

[0066] S5. The data service layer queries the database through the driver program and provides services to the business logic layer after service processing.

[0067] This method splits the backend service code of the software into two layers, the upper layer microservice performs business logic processing and data interface definition, and the lower layer microservice is responsible for connecting to the underlying database and implementing data services. In the case of switching the underlying database, it is only necessary to complete the development and adaptation of the lower layer microservice, and then replace and deploy the lower layer microservice. This method divides the backend service architecture of the software into layers and refines it, and standardizes the definition of the data interface layer. The lower layer microservice will not involve changes to the upper layer business logic code during the adaptation and development process, and the microservice development of the data service layer is directly carried out according to the interface and interface function description. This method is mainly used to simplify the workload of software products in the background service development process of adapting and switching the underlying database, optimizing code logic, and improving development efficiency and product reliability.

The control layer is mainly responsible for the interface definition with the interaction layer; the data interface layer is responsible for the interface definition with the data service layer; and the service layer is responsible for business logic processing.
