方法一、配置welcome-file-list和servlet-mapping

<!-- 将默认欢迎页配置为要访问的controller路径 -->

<welcome-file-list>

<welcome-file>task/code.do</welcome-file>

</welcome-file-list>

<!-- 配置拦截的后缀 -->

<servlet-mapping>

<servlet-name>DispatcherServlet</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

 

方法二、同样是配置welcome-file-list和servlet-mapping

<!-- 不用.do后缀 -->

<welcome-file-list>

<welcome-file>task/code</welcome-file>

</welcome-file-list>

<!-- 另外配置一个servlet-mapping拦截欢迎页配置的路径 -->

<servlet-mapping>

<servlet-name>DispatcherServlet</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>DispatcherServlet</servlet-name>

<url-pattern>/task/code</url-pattern>

</servlet-mapping>
