SpringMVC可以配置多个拦截后缀*.html和.do等

一个servlet可以配置多个servlet-mapping，

因此在xml文件中我们可以这样配置：

    <!-- springmvc配置 -->

    <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:config/dispatcher-servlet.xml</param-value>

        </init-param>

        <load-on-startup>2</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>springmvc</servlet-name>

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

    </servlet-mapping>

    <servlet-mapping>

        <servlet-name>springmvc</servlet-name>

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

    </servlet-mapping>
