本文记录了一次Tomcat启动失败的问题排查过程，错误源于web.xml文件中的<url-pattern>配置不正确，通过将*</url-pattern>更改为/*</url-pattern>解决了启动问题。

今天下了一个工程，启动时报了下面这个错误

我查了一下web.xml中

<filter-mapping> <filter-name>SetCharacterEncoding</filter-name> <url-pattern>*</url-pattern> </filter-mapping>

把<url-pattern>*</url-pattern> 修改为

<url-pattern>/*</url-pattern>

重新启动，问题解决
