spring+struts2+hibernate+ligerui+json整合开发(带分页)
说明：
1、后台程序是参考本公司“杜师傅”的例子！加上自学了ligerui，整合来使用！
2、最近在做一个项目，使用到了上面的技术，不知道现在ssh发展到了上面地步，是不是已经快淘汰了，发现springMVC+mybatis、hibernate+esayui、juqeryui等是企业级应用比较广泛，本人在大学期间，就是学习ssh整合开发，个人感觉现在ssh在java企业应用中还是普遍存在的吧！
3、重在个人总结，技术积累，有什么不好的地方，还请各位牛人指点！相互学习、相互进步。
话不多说，下面是整合信息
一、项目结构：
二、把需要的jar包添加到lib目录，配置web.xml、applicationContext.xml

String sql = "select " +

if(dataList!=null&&dataList.size()>0)
{
for(int i=0;i dao中的分页类
package com.common;
import java.sql.PreparedStatement;

import java.util.List;
import org.hibernate.Session;
import com.tool.DBEncoding;
public class PageUnit{
public static int getPageCount(Session session,String sql, List data, int pageSize)

try {
list = userdao.userList(data, pageNow, pageSize);
} catch (Exception e) {
// TODO Auto-generated catch block

}
return list;
}
}这时候 应该写个测试类来测试一下结果
package com.test;
import java.util.List;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.factory.SpringContextFactory;
import com.service.UserService;
public class UserDaoTest {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
ClassPathXmlApplicationContext act=SpringContextFactory.getSpringContext();
UserService us = (UserService)act.getBean("UserService");
List list = us.userList(null, 1, 10);
for(int i=0;iaction 类
package com.action;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;

import com.factory.SpringContextFactory;
import com.opensymphony.xwork2.ActionSupport;
import com.service.UserService;
public class UserAction extends ActionSupport{
private int pageNow = 1;
private int pageSize = 10;
private JSONObject Rows;
private String action;
@SuppressWarnings("unchecked")
public String execute(){
//HttpServletRequest request=ServletActionContext.getRequest();
ClassPathXmlApplicationContext act=SpringContextFactory.getSpringContext();
UserService us = (UserService)act.getBean("UserService");
if(action.equals("ulist")){
List userList = us.userList(null, pageNow, pageSize);
/**
* json
*/
HashMap maprow = new HashMap();
if(userList!=null&&userList.size()>0){
String Total=(((Map)userList.get(0)).get("Total"))+"";
maprow.put("Rows", userList);
maprow.put("Total", Total);
}
Rows =JSONObject.parseObject(JSON.toJSONString(maprow));
System.out.println(Rows);
return SUCCESS;
}
return ERROR;
}
public int getPageNow() {
return pageNow;
}
public void setPageNow(int pageNow) {
this.pageNow = pageNow;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public JSONObject getRows() {
return Rows;
}
public void setRows(JSONObject rows) {
Rows = rows;
}
public String getAction() {
return action;
}
public void setAction(String action) {
this.action = action;
}
}
Rows
下面 来使用ligerui的ligerGrid查询显示列表数据,userlist.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
用户列表
<%@include file="include/head.jsp" %>
显示结果
