   swagger2使用說明：
         @Api：用在類上，說明該類的作用
         @ApiOperation：用在方法上，說明方法的作用
         @ApiIgnore：使用該注解忽略這個API
         @ApiImplicitParams：用在方法上包含一組參數(shù)說明
         @ApiImplicitParam：用在@ApiImplicitParams注解中，指定一個請求參數(shù)的各個方面
            paramType：參數(shù)放在哪個地方
                 header-->請求參數(shù)的獲?。篅RequestHeader
                 query-->請求參數(shù)的獲?。篅RequestParam
                 path（用于restful接口）-->請求參數(shù)的獲?。篅PathVariable
                 body（不常用）
                 form（不常用）
             name：參數(shù)名
             dataType：參數(shù)類型
             required：參數(shù)是否必須傳
             value：參數(shù)的意思
             defaultValue：參數(shù)的默認值
         @ApiResponses：用于表示一組響應
         @ApiResponse：用在@ApiResponses中，一般用于表達一個錯誤的響應信息
             code：數(shù)字，例如400
             message：信息，例如"請求參數(shù)沒填好"
             response：拋出異常的類
         @ApiModel：描述一個Model的信息（這種一般用在post創(chuàng)建的時候，使用@RequestBody這樣的場景，請求參數(shù)無法使用@ApiImplicitParam注解進行描述的時候）
            @ApiModelProperty：描述一個model的屬性
