Question

struts2的action把返回的参数带到另外一个action实例求解：

一个action类执行后返回一些参数，这些参数根据result跳转到另一个action类中，如何把返回的这些参数带到另一个action中呢？求简单实例

Answer 1

恩，你的这个result直接返回chain方法就可以了

给你个实例吧

 

<package name="mystruts1" extends="struts-default" namespace="/mystruts1">
<!-- 第一个Action -->
<action name="test_*" class="com.action.TestAction" method="{1}">
<result name="text_chain" type="chain">result_resultChain</result>
</action>
<!-- 第二个Action -->
<action name="result_*"  class="com.action.ResultAction" method="{1}"></action>
</package>
public class TestAction {
public String testChain(){
HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
request.setAttribute("param", "test");
return "text_chain";
}
}
public class ResultAction {
public String resultChain(){
HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
System.out.println(request.getAttribute("param"));
return null;
}
}
