然后启动tomcat就出现上面的报错。应该是我的WEB.XML路径问题，可是我检查了，没有错误字母，并且已经让大小写敏感！已经头大了，请各位老鸟帮忙，谢谢啦！

[解决办法]
提示的挺清楚的：
Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> com/Chuli01 in servlet mapping
所以显然不是“应该是我的WEB.XML路径问题”

就是这个写错误了：
<url-pattern>com/Chuli01</url-pattern>

改成：
<url-pattern>/com/Chuli01</url-pattern>
