嚴重: Error deploying configuration descriptor [D:\apache-tomcat-8.5.23\conf\Catalina\localhost\ssm.xml]

java.lang.IllegalStateException: Container

這個問題在同僚的電腦上出現的,而且還重複出現. 

産生這個問題的問題的根本原因是Tomcat的conf/server.xml檔案的問題,對比了我電腦上和同時電腦上的這個檔案,發現多了了一句:

<Context docBase="D:\programfiles\apache-tomcat-8.5.23\wtpwebapps\youknow" path="/youknow" reloadable="true" source="org.eclipse.jst.jee.server:youknow"/>

解決這個問題發現了兩個方法,

1)eclipse下輕按兩下Tomcat,在他的配置檔案下,取消 Server Options下的Pubish module....的勾選,

2)去Tomcat的conf/server.xml下,删除:

<Context docBase="D:\programfiles\apache-tomcat-8.5.23\wtpwebapps\youknow" path="/youknow" reloadable="true" source="org.eclipse.jst.jee.server:youknow"/>
