	    <action name="r4">
	    	<result type="redirectAction">r2</result>
	    	<!--  <result type="redirectAction">r1</result> -->
	    </action>
	    
    </package>
</struts>

 

dispatcher:服务器内部转发，默认的.

 

redirect:客户端重定向.

 

chain:用于转发到另外的action,如果这个action在另处的package:使用下面写法 

 <action name="login" class="...">
        <!-- Chain to another namespace -->
        <result type="chain">
            <param name="actionName">dashboard</param>
            <param name="namespace">/secure</param>
        </result>
    </action>

 路径显示是这个action

 

 

 

redirectAction:重定向到另外的action
