Error starting static Resources java.lang.IllegalArgumentException: Document base D:\eclipse\*\wtpwebapps\* does not exist or is not a readable directory问题的解决

　　今天，在eclipse上想整理下过去的项目，把之前没用的一些项目删了，把一些项目改了下名，结果再启动jsp页面的时候就出现了以下错误并提示Tomcat启动失败。

严重: Error starting static Resources
java.lang.IllegalArgumentException: Document base D:\eclipse\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\A2019.09.00--xiao_xue_qi does not exist or is not a readable directory

　　记得之前遇到过类似的问题，应该不是什么大问题，就没有尝试重装Tomcat之类的会浪费时间，我查看了Tomcat下的server.xml文件，在文件最下方看到以下代码：

<Context docBase="KCPingTai_" path="/KCPingTai_" reloadable="true" source="org.eclipse.jst.jee.server:KCPingTai_"/>
    <Context docBase="wjdc" path="/wjdc" reloadable="true" source="org.eclipse.jst.jee.server:wjdc"/>
    <Context docBase="A2019.09.00--xiao_xue_qi" path="/A2019.09.00--xiao_xue_qi" reloadable="true" source="org.eclipse.jst.jee.server:A2019.09.00--xiao_xue_qi"/>
    <Context docBase="Zu_Pu_Analysis" path="/Zu_Pu_Analysis" reloadable="true" source="org.eclipse.jst.jee.server:Zu_Pu_Analysis"/>

     </Host>

　　把所有四行代码删除：Tomcat启动正常但网页报404；

　　只留下要启动项目的代码：项目完美运行；

　　再把代码还原就会出现同样的error；

　　原来问题出在这里，问题解决！
