将应用部署到tomcat上报warning: The web application [ROOT] appears to have started a thread named [Abandoned

将应用部署到tomcat上报warning: The web application [ROOT] appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak.

将应用部署到tomcat上报标题warning, 并且并不影响部署和运行, 后来发现原因是之前的应用导入的jar包,add as lirbrary的level设置成了project library. 而现在部署的是maven应用,通过依赖导入的jar包和之前导入的jar包发生了冲突.
参考了这位大佬的描述
发现是mysql-connector-java这个jar包的原因

打开Project Structure将之前导入的jar包删除即可
