Ext+Struct2 纯OO实现相互交互

折腾了两天 终于弄明白了是这样一回事

js 代码为

/********创建FormPanel*******/

		System.out.println("这一行输出s-"+p.getPname()+p+"-");
		super.outJsonString("{success:true,msg:'成功加载'}");

structs xml 配置

<?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>
	<package name="back" extends="struts-default" namespace="/">
		<global-results>
			<result name="done">result.jsp</result>
		</global-results>
		<action name="*action_*" class="com.ysu.action.{1}Action" method="{2}"></action>
	</package>

</struts>

javabean代码为

package com.ysu.entity;
import java.io.Serializable;
public class ProductEntity implements Serializable {
	private String pname;
	private String pnum;
	private String pcheck;
	private String pdate;
	private String ptype;
	//省略 get和 set 方法
}

data.jsp的数据为

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
[
{pname:'GH-2323零件',ptype:'固件',pnum:18,pdate:'2009-7-11 00：00：00',pcheck:'合格'},
