 swagger2使用说明：
 @Api：用在类上，说明该类的作用
 @ApiOperation：用在方法上，说明方法的作用
 @ApiIgnore：使用该注解忽略这个API
 @ApiImplicitParams：用在方法上包含一组参数说明
 @ApiImplicitParam：用在@ApiImplicitParams注解中，指定一个请求参数的各个方面
 paramType：参数放在哪个地方
 header-->请求参数的获取：@RequestHeader
 query-->请求参数的获取：@RequestParam
 path（用于restful接口）-->请求参数的获取：@PathVariable
 body（不常用）
 form（不常用）
 name：参数名
 dataType：参数类型
 required：参数是否必须传
 value：参数的意思
 defaultValue：参数的默认值
 @ApiResponses：用于表示一组响应
 @ApiResponse：用在@ApiResponses中，一般用于表达一个错误的响应信息
 code：数字，例如400
 message：信息，例如"请求参数没填好"
 response：抛出异常的类
 @ApiModel：描述一个Model的信息（这种一般用在post创建的时候，使用@RequestBody这样的场景，请求参数无法使用@ApiImplicitParam注解进行描述的时候）
 @ApiModelProperty：描述一个model的属性
