springboot整合swagger2步骤demo

您好，以下是springboot整合swagger2的步骤demo：

1. 在pom.xml文件中添加swagger2的依赖：

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>

2. 创建Swagger2配置类，用于配置Swagger2相关信息：

@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2构建RESTful APIs")
                .description("更多Spring Boot相关文章请关注：http://www.example.com/")
                .termsOfServiceUrl("http://www.example.com/")
                .contact("example")
                .version("1.0")
                .build();
    }
}

3. 在Controller类中添加Swagger2注解，用于描述接口信息：

@RestController
@RequestMapping("/user")
@Api(tags = "用户管理")
public class UserController {
    @ApiOperation(value = "获取用户列表", notes = "获取所有用户列表")
    @GetMapping("/list")
    public List<User> list() {
        // ...
    }

    @ApiOperation(value = "创建用户", notes = "根据User对象创建用户")
    @ApiImplicitParam(name = "user", value = "用户实体", required = true, dataType = "User")
    @PostMapping("/create")
    public String create(@RequestBody User user) {
        // ...
    }

    @ApiOperation(value = "更新用户", notes = "根据User对象更新用户")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"),
            @ApiImplicitParam(name = "user", value = "用户实体", required = true, dataType = "User")
    })
    @PutMapping("/update/{id}")
    public String update(@PathVariable Long id, @RequestBody User user) {
        // ...
    }

    @ApiOperation(value = "删除用户", notes = "根据ID删除用户")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @DeleteMapping("/delete/{id}")
    public String delete(@PathVariable Long id) {
        // ...
    }
}

4. 启动应用程序，访问http://localhost:8080/swagger-ui.html，即可查看Swagger2生成的接口文档。

希望对您有所帮助！
