SpringBoot>10 - 集成Swagger2

简介：

本章介绍 SpringBoot1.5 集成 Swagger2 生成在线的API接口文档。

个人学习总结：
链接：【springboot、springcloud、docker 等，学习目录】

1、pom依赖：

    
    
        io.springfox
        springfox-swagger2
        2.2.2
    
    
        io.springfox
        springfox-swagger-ui
        2.2.2
    

2、Swagger2Config配置类：

/**
 * @Description:  swagger2配置类
 */
@Configuration
// 开启swagger2
@EnableSwagger2
// 选择不同的环境启用 swagger  以下两种方式，推荐第一种
//@Profile({"dev","test"})
//@ConditionalOnProperty(name = "swagger.enable", havingValue = "true")
public class Swagger2Config {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.coolron"))
                .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：.......")
                .termsOfServiceUrl("http://blog.coolron.com/")
                .contact("A罗恩和Java")
                .version("1.0")
                .build();
    }
}

3、改造UserController类：

@Slf4j
@Api(description = "用户接口")
@RestController
@RequestMapping(value = "user")
public class UserController {

    @Autowired
    private UserService userService;

    @ApiOperation(value="获取用户列表", notes="")
    @RequestMapping(value={"getUserList"}, method= RequestMethod.GET)
    public ApiResult getUserList() {
        List userList = userService.getAllUser();
        return ApiResult.ok(userList);
    }

    @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="saveUser", method=RequestMethod.POST)
    public ApiResult saveUser(@RequestBody User user) {
        int result = userService.saveUser(user);
        return ApiResult.ok(result);
    }

    @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 = "getUser", value = "用户ID", required = true, dataType = "Long")
    @RequestMapping(value="getUser/{id}", method=RequestMethod.GET)
    public ApiResult getUser(@PathVariable Integer id) {
        User user = userService.getUser(id);
        return ApiResult.ok(user);
    }

    @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="updateUser/{id}", method=RequestMethod.PUT)
    public ApiResult putUser(@PathVariable Integer id, @RequestBody User user) {
        int result = userService.updateUser(user);
        return ApiResult.ok(result);
    }

    @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="delete/{id}", method=RequestMethod.DELETE)
    public ApiResult deleteUser(@PathVariable Integer id) {
        int result = userService.deleteUser(id);
        return ApiResult.ok(result);
    }
}

4、测试：访问http://localhost:8080/swagger-ui.html
注意： 访问路径有配置工程名的带上工程名，避免404。此处未配置工程名。

5、使用：GET、POST、PUTD、DELETE等请求方式都可以在此测试，输入必要的参数点击“try it out”按钮即可。
