第六章 result配置的各种视图转发类型

dispatcher 默认
redirect 
redirectAction
plainText


dispatcher默认方式:
struts.xml:
<package name="base" extends="struts-default">
        <global-results> //全局
		<result name="message">/WEB-INF/page/message.jsp</result>
	</global-results>
</package>
<package name="itcast" namespace="/control/employee" extends="base"> //继承base
	<action name="list" class="cn.itcast.action.HelloWorldAction" method="execute">
		<result name="success">/employeeAdd.jsp?username=${username}</result> //${}访问action中属性
	</action>
</package>


访问http://localhost:8080/struts2/control/employee/list,浏览器url地址不变
redirect:
struts.xml:
<package name="itcast" namespace="/control/employee" extends="base">	
		
	<action name="list" class="cn.itcast.action.HelloWorldAction" method="execute">
		<result name="success" type="redirect">/employeeAdd.jsp?username=${username}</result>
	</action>
</package>


地址浏览器url变化:http://localhost:8080/struts2/employeeAdd.jsp?username=liming


重定向到指定action,redirectAction:
<action name="redirectAction">
	<result type="redirectAction">list</result>
</action>


如果action在其他包中
<action name="redirectAction">
	<result type="redirectAction">
		<param name="actionName">helloWorld</param>  //重定向action名字
		<param name="namespace">/test</param>   //重定向action的namespace
	</result>
</action>




plainText,打印源代码:
<action name="plainText">
	<result type="plainText">
		<param name="location">/index.jsp</param>
		<param name="charSet">UTF-8</param>
	</result>
</action>
