場景描述：
電腦開機後，第一次啓動項目不報錯，但是中途停止了項目，再重啓時，console臺會報以下錯誤，但是項目只可以正常運行，只是看着報錯很不爽，並且也不方便截報文。
待解決問題：
警告: The web application [bssCustManage] appears to have started a thread named [Log4j2-TF-7-AsyncLoggerConfig-1] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

報錯原因
文件被佔用，當前用戶下的.dubbo文件夾下的文件被佔用
解決方法：
1、關閉項目，刪除.dubbo文件夾下的文件，再重啓項目就不報錯了。
