我正在尝试使用tomcat运行spring mvc基本应用程序并获取http 404错误。我得到以下启动错误。这是以前工作，我不知道we.xml出了什么问题

答案 0 :(得分：6)
在stackTrace中看到这个
引起：java.lang.IllegalArgumentException：Servlet映射指定未知的servlet名称frontcontrol
你有frontControl的servlet映射....但没有相应的SERVLET标签......
我认为这应该是正确的映射。
<servlet>
<servlet-name>frontcontrol</servlet-name><!-- Notice this line changed-->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>frontcontrol</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
