Introduction to the use of Swagger's annotation framework in the Java library

Introduction to the use of Swagger's annotation framework in the Java library The Swagger annotation framework is a tool for building a RESTFUL API. It can help developers use simple and powerful annotations in the Java library to describe the API interface and data model.Through the Swagger annotation framework, developers can easily create API documents and test and debug the API interface. Use the Swagger Note Framework in the Java Library. First of all, you need to add the dependency item of the Swagger annotation framework to the project dependency management tool. For example, the use of the Maven project can be added to the pom.xml file: <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> Next, the Swagger annotation framework is enabled in the configuration class of the Spring Boot application: @Configuration @EnableSwagger2 public class SwaggerConfig { @Bean public Docket api() { return new Docket(DocumentationType.SWAGGER_2) .select() .apis(RequestHandlerSelectors.any()) .paths(PathSelectors.any()) .build(); } } In the above code, the Swagger configuration class is used through the @Configuration annotation mark, and the Swagger annotation framework is enabled by@ENableswagger2 annotations, and the choice of API interface and path is set through Docket Bean. When writing the API interface in the Java class library, you can use the swagger annotation to describe the API interface and data model, such as: @API (tags = "User Management Interface") @RestController @RequestMapping("/users") public class UserController { @APIPERATION ("Get all user information") @GetMapping public List<User> getAllUsers() { // Get the logic of all user information } @APIPERATION ("Obtain user information based on ID") @GetMapping("/{id}") public User getUserById(@PathVariable Long id) { // Obtain the logic of user information according to ID } @APIPERATION ("Add user information") @PostMapping public User addUser(@RequestBody User user) { // Add the logic of user information } // ... other API interface methods } In the above code, the label of the user's management interface is described through the @API annotation, and the specific API interface method is described through the @APIPERATION annotation, including the description, request method, request path and other information of the method. Through the above introduction, we can see that the use of the Swagger annotation framework in the Java class library is very simple and powerful. In project development, it can provide developers with convenient API interface management and document generation functions.
