The technical ideas designed by the Swagger annotation framework in the Java class library for Restful API

Use the Swagger Note Framework in the Java Library for technical ideas designed by RESTFUL API When designing the RESTFUL API, using the Swagger annotation framework can greatly simplify the development process and provide the function of automatically generating API documents and client code.This article will introduce the technical ideas of the Swagger annotation framework in the Java library to design the restful API design, and provide the corresponding Java code example. 1. Introduce Swagger dependencies First, the Swagger dependencies are introduced in the POM.XML file of the Java project.You can use the following code fragments as a reference: <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency> 2. Create API document configuration class Next, create a configuration class to configure the basic information of the API document generated by Swagger.You can use the following code example as a reference: @Configuration @EnableSwagger2 public class SwaggerConfig { @Bean public Docket api() { return new Docket(DocumentationType.SWAGGER_2) .select() .apis(RequestHandlerSelectors.basePackage("com.example.api")) .paths(PathSelectors.any()) .build() .apiInfo(apiInfo()); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title ("Restful API Document")) .descripting ("This is an API document generated using the Swagger annotation framework") .version("1.0.0") .build(); } } 3. Use Swagger annotation for API design Use the Swagger annotation on the controller class and method to define the basic information and parameter information of the API.Here are some commonly used Swagger annotations and examples of use: -`@API`: The resource of the label controller class is the Swagger document. -`@Apioperation`: Mark the specific API operation and provide descriptive information. -`@APIPARAM`: Add the parameter description of the API method. -`@Apiresponse`: The return result description of the API method. -`@Apimodel`: Define the data model of the API. -`@Apimodelproperty`: Define the attributes of the API data model. The following is the code of a sample controller class: @RestController @RequestMapping("/api") @API (tags = "User Management") public class UserController { @GetMapping("/users") @APIPERATION ("Get all users") public List<User> getAllUsers() { // Logic implementation } @PostMapping("/users") @APIPERATION ("Create User") public user creeser (@Requestbody @apiparam ("user information") user user) { // Logic implementation } // Other API methods ... } 4. Start the application and view the API document After completing the above steps, start the application and access the Swagger UI interface (generally http: // localhost: terminal number /SWAgger-UI.html), and you can view the generated API document. The Swagger UI interface provides interactive testing and document browsing functions for API. Developers can quickly implement the client based on the code automatically generated by the document. In summary, by using the Swagger annotation framework in the Java class library, you can simplify the design and development process of the RESTFUL API, and provide the function of automatically generating API documents and client code, which greatly improves development efficiency.Using the above technical ideas and code examples, you can quickly use the Swagger annotation framework for API design.
