SpringBoot +Swagger2整合使用示范

添加依赖：

<!--        Swagger2-->
        <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>

添加配置

@Configuration
@EnableSwagger2
public class SwaggerConfig implements WebMvcConfigurer {

    @Bean
    public Docket createRestApi()
    {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(getApiInfo()).select().apis(RequestHandlerSelectors.basePackage("com.humorchen.springboot_test.controller")).paths(PathSelectors.any()).build();
    }
    private ApiInfo getApiInfo()
    {
        return new ApiInfoBuilder().title("SprintBoot学习测试接口文档").description("描述信息：author:humorchen").contact("联系信息：qq3301633914").version("1.0").build();
    }
}

使用注解开发
实体类

@Component
@TableName("`User`")
@ApiModel("用户实体类")
public class User implements Serializable {
    private static final long serialVersionUID = 1L;
	@ApiModelProperty(value = "用户唯一标识",required = false,hidden = true)
	@TableId(value="id", type= IdType.AUTO)
	private Integer id;
	@ApiModelProperty("用户名")
	private String username;
	@ApiModelProperty("用户密码")
	private String password;
	//getter setter...
}


/**

@RestController
@RequestMapping("/springboot_test/user")
@Api(value = "用户接口")
public class UserController {
    @Autowired
    private IUserService iUserService;

    private final static Logger logger = LoggerFactory.getLogger(UserController.class);


	@GetMapping(value = "/{id}")
    @ApiOperation("根据用户唯一标识获取用户信息")
    public R getUser(@PathVariable @NonNull @ApiParam("用户唯一标识") String id)
    {
        return new R(iUserService.selectById(id));
    }

    @GetMapping(value = "/")
    @ApiOperation("获取所有用户")
    public R getAllUser(){
        return new R(iUserService.selectList(null));
    }

    @PostMapping(value = "/")
    @ApiOperation("添加用户")
    public R addUser(@RequestBody @ApiParam("用户信息") User user){
	    if(iUserService.insert(user)){
	        return new R().success("注册成功",user);
        }
	    return new R().error("注册失败");
    }


    @PutMapping(value = "/{id}")

    @ApiOperation("修改用户信息")
    public Object updateUser(@PathVariable @ApiParam(value = "用户唯一标识符") String id,@RequestBody @ApiParam(value = "用户信息") User new_user){
        User existed=iUserService.selectById(id);
        if(existed==null){
            return new R().error("用户不存在");
        }
        new_user.setId(existed.getId());
        //权限检查
        if(iUserService.updateById(new_user)){
            return new R().success("用户信息更新成功",new_user);
        }
        return new R().error("用户信息修改失败");
    }
