SpringFox Swagger2注解基本用法

一切参数说明，参考官方API文档：http://docs.swagger.io/swagger-core/current/apidocs/index.html?io/swagger/annotations

在实体和API注释这块，有些注释不一定在页面上表现，但是接口返回的数据上全部都有返回。

Swagger2出自SpringFOX， 官网：https://github.com/springfox/springfox，而与https://swagger.io/不同，所以在https://swagger.io/上是找不到Swagger2的开发文档。

在Swagger2的GitHUb页面上也没提供相关的详细文档，不过可以参考示例代码库https://github.com/springfox/springfox-demos进行参考。

不过下面这些网址还能找到关于Swagger的先关API文档，并且兼容Swagger2的：

http://docs.swagger.io/swagger-core/current/apidocs/index.html

https://github.com/swagger-api/swagger-core（旧版示例）

https://github.com/swagger-api/swagger-core/wiki/Annotations-1.5.X#quick-annotation-overview

https://github.com/swagger-api/swagger-samples（新版示例）

下面是收集的一些常用注解，如果要更多的用法，可以参照上面官网提供的文档：

名称描述
@Api 将类标记为Swagger资源。
@ApiImplicitParam 表示API操作中的单个参数。
@ApiImplicitParams 允许多个ApiImplicitParam对象列表的包装器。
@ApiModel 提供有关Swagger型号的其他信息。
@ApiModelProperty 添加和操作模型属性的数据。
@ApiOperation 描述针对特定路径的操作或通常的HTTP方法。
@ApiParam 为操作参数添加额外的元数据。
@ApiResponse 描述操作的可能响应。
@ApiResponses 允许多个ApiResponse对象列表的包装器。
@Authorization 声明在资源或操作上使用授权方案。
@AuthorizationScope 描述OAuth2授权范围。
@ResponseHeader 表示可以作为响应的一部分提供的头。

示例代码：
