Struts2--带参数的结果集

时间：2021-01-17 20:56:35

带参数的结果集:

配置文件: <result type="redirect">/user_success.jsp?t=${type}</result>

jsp调用 :

from valuestack: <s:property value="t"/><br/>   //取不到,因为客户端跳转后 以前action的值都没有了.
from actioncontext: <s:property value="#parameters.t"/>

1. jsp显示文件:]

<ol>

	<li><a href="user/user?type=1">传参数</a></li>

</ol>

2. struts.xml配置文件:

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constant name="struts.devMode" value="true" />

    <package name="user" namespace="/user" extends="struts-default">

	    <action name="user" class="com.bjsxt.struts2.user.action.UserAction">

	    	<result type="redirect">/user_success.jsp?t=${type}</result>

	    </action>

    </package>

</struts>

3. action文件:

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

	private int type;

	public int getType() {

		return type;

	}

	public void setType(int type) {

		this.type = type;

	}

	@Override

	public String execute() throws Exception {

		return "success";

	}

}

　　

　

4. user_success.jsp:

<body>

	User Success!

	from valuestack: <s:property value="t"/><br/>  取不出来, 因为客户端跳转, 值栈已清空

	from actioncontext: <s:property value="#parameters.t"/>

	<s:debug></s:debug>

</body>
