原因：此类错误注意看报错提示。异常来自类路径资源[applicationcontext.xml]的xml文档中的第6行无效；嵌套异常为org.xml.sax.saxparseexception；行号：6；多生成一个标签。

附上错误原码：

<!-- action -->
<bean name="useraction" class="cn.itcast.web.action.useraction" ></bean>
<!-- service -->
<bean name="userservice" class=<element>"cn.itcast.service.impl.userserviceimpl"</element>></bean>
