警告: No mapping found for HTTP request with URI的解决方案

使用springMVC，访问action时报错：

2015-12-29 16:37:11 org.springframework.web.servlet.DispatcherServlet noHandlerFound

警告: No mapping found for HTTP request with URI [/springmvc/index.jsp] in DispatcherServlet with name 'mvc-dispatcher'

后来排查是这里的问题：

在web.xml中

<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<strong><url-pattern>/*</url-pattern></span></strong>
</servlet-mapping>

修改为： 

<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<strong><url-pattern>*.action</url-pattern></span></strong>
</servlet-mapping>
