web.xml中使用web前缀配置无法访问controller

<web:context-param>
<web:param-name>contextConfigLocation</web:param-name>
<web:param-value>classpath:spring/applicationContext.xml</web:param-value>
</web:context-param>

<web:listener>
    <web:listener-class>org.springframework.web.context.ContextLoaderListener</web:listener-class>
    </web:listener>

<web:listener>
<web:listener-class>org.springframework.web.util.IntrospectorCleanupListener</web:listener-class>
</web:listener>


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

使用上面这种配置是不行的。

把web: 去掉

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>


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