待补的struts

                                             Struts是一个大的Servlet；

 

 

Struts:
actionServlet:是前端控制器；
<action path="/" type="类名"></action>
<forward  name="" path="视图"></forward>

el和动态表单结合时，用el取值时el要加map
${xx.map.name}

mapping.findForward("m")和<forward name="m" path="/xx.jsp"></forward>相对应；

在conf/web.xml下把<param-value>true</param-value>中改成true就可以在浏览器端列出所有目录；

代码如下：
<servlet>
        <servlet-name>default</servlet-name>
        <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>0</param-value>
        </init-param>
        <init-param>
            <param-name>listings</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
