使用IDEA在tomcat中部署maven多模块时出现的令人费解的错误
首先用服务器打印。 可以看到上下文[ ] startupfailedduetopreviouserror，see server log for details。

然后打开tomcat日志的位置，显示框架- base的ConfigItem NotFound。

war包下的lib中仍然没有框架- base、springwork-mybatis等子模块的jar包：
显然，当您使用idea单击tomcat运行时，在编译打包过程中我们的子模块是否丢失了？ 带着问题继续看IDEA的日志。

百度半天后，我们发现没有加载此context文件不是错误的根源，而是子模块的jar包未导入时发生的子错误。
幸运的是，最终发现了错误。 查看下图中artifacts的lib中没有子模块的jar包，首先单击lib，在available elements的中点打开相应的模块，然后单击
打包Into进入。
最后点击运行就可以了。
洞。
