进行标记对应的注释：

@RestController

}
return ResponseEntity.ok(r);
}

@ApiIgnore//使用该注解忽略这个API
@RequestMapping(value = "/hi", method = RequestMethod.GET)
public String jsonTest() {
return " hi you!";
}
在编写完后，我们进行运行我们的项目后可以访问http://localhost:8080/swagger-ui.html 进行访问Swagger2的相关内容。注意：端口号为server.port定义的，根据自己定义的更换。

注解 描述
@Api 修饰整个类，描述Controller的作用
@ApiOperation 描述一个类的一个方法，或者说一个接口

@ApiModel 用对象来接收参数
@ApiProperty 用对象接收参数时，描述对象的一个字段
@ApiResponse HTTP响应其中1个描述
@ApiResponses HTTP响应整体描述
@ApiIgnore 使用该注解忽略这个API
@ApiError 发生错误返回的信息
@ApiImplicitParam 一个请求参数
@ApiImplicitParams 多个请求参数
