项目结构：

框架整合所需jar

注：xwork-core-2.1.6选择2.1.6版本内含SpringUtil.class

	 * 修改用户
	 */
	public void update(Custom user);
	/*
	 * 按Id获取用户
	 */

	}
	

}

6、applicationContext.xml

	
	
	
	
	
		
			classpath:database.properties

11、CustomAction

package cn.ddj.action;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONObject;

import org.apache.struts2.ServletActionContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import cn.ddj.entity.Custom;
import cn.ddj.service.CustomBiz;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;


@Scope("prototype")
@Controller("customAction")
public class CustomAction extends ActionSupport{

	private static final long serialVersionUID = 1L;

	private List customs;
	private Map dataMap = new HashMap();
	private Integer id;
	private String cname;
	private String caddress;
	private String cemail;
	private String cpost;
	private Custom custom = new Custom();
	
	@Autowired
	@Qualifier("customBiz")
	private CustomBiz customBiz;
	
	public Custom getCustom() {
		return custom;
	}

	public void setCustom(Custom custom) {

	}

	public void setCustomBiz(CustomBiz customBiz) {
		this.customBiz = customBiz;
	}

	public List getCustoms() {
		return customs;
	}

	public void setCustoms(List customs) {
		this.customs = customs;
	}

	public String getCname() {
		return cname;
	}

	public void setCname(String cname) {
		this.cname = cname;
	}

	public String getCaddress() {
		return caddress;
	}

	public void setCaddress(String caddress) {
		this.caddress = caddress;
	}

	public String getCemail() {
		return cemail;
	}

	public void setCemail(String cemail) {
		this.cemail = cemail;
	}

	public String getCpost() {
		return cpost;
	}

	public void setCpost(String cpost) {
		this.cpost = cpost;
	}
	
	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public Map getDataMap() {
		return dataMap;
	}

	public void setDataMap(Map dataMap) {
		this.dataMap = dataMap;
	}


	
	
	public String jsonall() {
		System.out.println("获取json格式");
		customs = customBiz.findAllUsers();
		// dataMap中的数据将会被Struts2转换成JSON字符串，所以这里要先清空其中的数据  
        dataMap.clear();  
		dataMap.put("customs", customs);
		dataMap.put("success", true);
		return SUCCESS;
	}
	
	
	public void jsonall2() throws IOException {
		System.out.println("传统servlet获取json格式");
		HttpServletResponse response=ServletActionContext.getResponse();
		response.setContentType("text/html");
		PrintWriter out;  
        out = response.getWriter();
        
        customs = customBiz.findAllUsers();

		JSONObject json=new JSONObject();
        json.accumulate("success", true);
        json.accumulate("custom", customs);
        
        out.println(json.toString()); 
        out.flush();  
        out.close(); 

	}
	


	
}

12、showall.jsp（引入jq和struts标签库）

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>



  
    
    
    
    
	
	
	    
	
	
	

  
  
 
 
  
  
   
   

   		 			
   			

   			

   				
客户ID
   				
客户名称
   				
客户地址
   				
邮箱地址
   				
邮政编码
   			
 			
   			

   				

   				

   				

   				

   				

   			
     			
   		
   
    
  

结果返回：

{"success":true,"custom":[{"caddress":"rrrr","cemail":"rrr","cname":"kkkk","cpost":"aaaa","customid":1},{"caddress":"sdfsdf","cemail":"[email protected]","cname":"sdfsdf","cpost":"fsdfsdf","customid":2}]}
