SSM項目IEDA啟動之后控制台一直輸出彈出spring的debug日志

錯誤信息

 在ssm項目啟動后，我的idea控制台不停地輸出類似如下的日志，導致我的項目無法正常處理請求：

我以為是我的代碼問題，最開始在博客中看到了可能是mapper映射文件的錯誤（諸如多了空格或者是結束標簽忘了加）， 比如這篇：CSDN上的博客 或 CSDN的博客

我便仔細地比對我的所有mapper映射文件，反復核對了許久並沒有出現像以上兩個博客遇到的錯誤，導致我撓頭皮撓了很久。

如果你不是以上關於mapper映射文件的問題，那么很可能就是我所遇到的問題。

解決方案

最終我從csdn上找到了原因，就是因為一個斷點的原因。。。我不知何時在一個service方法上面添加了斷點，而這就是造成這一切的罪魁禍首。

然后我就找斷點的位置，百度找了一遍，發現我的debug窗口不見了，無法查看斷點，但是百度上都是從debug窗口找到的斷點列表（我也重置了窗口布局並沒有用），自己摸索了一下，找到了斷點列表：

 在底部工具欄的 Favorites 窗口內部有一個斷點列表，沒想到收藏夾居然還有斷點，不得不說IDEA挺不錯的。

清理完斷點后，我的項目終於可以正常運行了，記錄一下避免以后重復踩坑吧。
