這裡寫圖片描述
這裡寫圖片描述
具體裡面的內容以及介面測試,應該一看就懂了。這裡就不一一截圖了。
五、Swagger註解 swagger通過註解表明該介面會生成文件,包括介面名、請求方法、引數、返回資訊的等等。
@Api:修飾整個類,描述Controller的作用 @ApiOperation:描述一個類的一個方法,或者說一個介面 @ApiParam:單個引數描述 @ApiModel:用物件來接收引數 @ApiProperty:用物件接收引數時,描述物件的一個欄位 @ApiResponse:HTTP響應其中1個描述 @ApiResponses:HTTP響應整體描述 @ApiIgnore:使用該註解忽略這個API @ApiError :發生錯誤返回的資訊 @ApiImplicitParam:一個請求引數 @ApiImplicitParams:多個請求引數
