今天用maven创建了一个工程，结果启动tomcat之后，报错了：
严重: ContainerBase.addChild: start:

后来我在网上搜了下，结果可能出现的错误信息很多，然后我就一一看了下：
web.xml里的信息没配置好。例如<url-pattern><url-pattern/>中少写<url-pattern>/<url-pattern/>，那个左斜杠没有写导致报错。这个是web.xml报错最多的原因。其他还有标签不匹配或者是写错标签。
于是我就改了在web.xml文件中的url：
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--解决中码的问题-->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
然后就okl
