今天一群友遇到一个问题，其错误提示如下
严重: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]
严重: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]后来经过排查，他的web.xml里面是这样配置的
<servlet-name>MyServlet</servlet-name> <url-pattern>/*.do</url-patern>很明显，这里的web.xml可能配置错了
因为根据此web.xml配置信息来看，他就是拦截的根目录下的*.do文件
而事实上他是想拦截所有以.do结尾的请求
因此，去掉斜杠，错误即可被解决
