struts2[3.5]在struts2配置文件中使用OGNL表达式

1.新建一个Demo3Action.java，只需重写execute()方法即可：

package com.aisino.b_config;

import com.opensymphony.xwork2.ActionSupport;

public class Demo3Action extends ActionSupport{

	private String name;       //还可以从数据库中获取
	@Override
	public String execute() throws Exception {
		name = "isleiyi";
		System.out.println("Demo3Action!");
		return SUCCESS;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

2.配置action:

<action name="Demo3Action" class="com.aisino.b_config.Demo3Action" method="execute" >
	<result name="success" type="redirectAction" >
		<param name="actionName">Demo1Action</param>
		<param name="namespace">/</param>
		<param name="name">${name}</param>
	</result>
</action>

运行，访问http://localhost:8080/sturts2_day03Test/Demo3Action

就获取到了name=isleiyi的值了，
