springboot怎么配置并使用swagger

步骤如下：

在pom.xml中添加swagger依赖

<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>

创建Swagger2配置类

@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：https://www.baidu.com/")
                .termsOfServiceUrl("https://www.baidu.com/")
                .contact("作者")
                .version("1.0")
                .build();
    }
}

在Controller中使用注解

@RestController
@Api(tags = "用户管理")
@RequestMapping("/user")
public class UserController {
    @ApiOperation(value = "获取用户列表", notes = "获取用户列表")
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public List<User> getUserList() {
        return null;
    }

    @ApiOperation(value = "创建用户", notes = "根据User对象创建用户")
    @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
    @RequestMapping(value = "/", method = RequestMethod.POST)
    public String postUser(@RequestBody User user) {
        return "success";
    }

    @ApiOperation(value = "获取用户详细信息", notes = "根据url的id来获取用户详细信息")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public User getUser(@PathVariable Long id) {
        return null;
    }

    @ApiOperation(value = "更新用户详细信息", notes = "根据url的id来指定更新对象，并根据传过来的user信息来更新用户详细信息")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long"),
            @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
    })
    @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
    public String putUser(@PathVariable Long id, @RequestBody User user) {
        return "success";
    }

    @ApiOperation(value = "删除用户", notes = "根据url的id来指定删除对象")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    public String deleteUser(@PathVariable Long id) {
        return "success";
    }
}

启动应用，访问swagger-ui.html

访问地址：http://localhost:8080/swagger-ui.html

以上就是在Spring Boot中配置并使用Swagger的步骤
