Spring Hibernate實現(xiàn)分頁功能

這篇文章主要為大家詳細(xì)介紹了Spring Hibernate實現(xiàn)分頁功能的相關(guān)代碼，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本實例采用Spring+Hibernate實現(xiàn)簡單的分頁功能，供大家參考，具體內(nèi)容如下

最關(guān)鍵的是運用Hibernate的query里面的兩個方法：

query.setFirstResult((p.getPage()-1)*p.getRows()); 指定從那個對象開始查詢，參數(shù)的索引位置是從0開始的。

query.setMaxResults(p.getRows()); 分頁時，一次最多產(chǎn)尋的對象數(shù) 主要實現(xiàn)類：

package com.paging;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Query;
import org.hibernate.SessionFactory;

import com.user.User;

import sun.nio.cs.US_ASCII;

public class Paging {
 final int num=3;
 @Resource
 SessionFactory sessionFactory;

 public void setSessionFactory(SessionFactory sessionFactory) {
 this.sessionFactory = sessionFactory;
 }
 
 
 public List<User> paging(int index) {
 
 String hql = "from User";
 Query query = sessionFactory.getCurrentSession().createQuery(hql);
 query.setFirstResult((index-1)*num);
 query.setMaxResults(num);
 
 return query.list();
 
 }
 
 
 
 

}

web層:

package com.web;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.paging.Paging;
import com.user.User;



@Controller
@RequestMapping("/Page")
public class Web {
 @Resource
 Paging paging;

 public void setPaging(Paging paging) {
 this.paging = paging;
 }
 
 
 @RequestMapping("/page")
 public String page(Model model,int index) {
 List<User> list = paging.paging(index);
 model.addAttribute("list", list);
 return "index";
 
 
 }
 
}

jsp頁面：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
 <base href="<%=basePath%>" rel="external nofollow" >
 
 <title>My JSP 'index.jsp' starting page</title>
 <meta http-equiv="pragma" content="no-cache">
 <meta http-equiv="cache-control" content="no-cache">
 <meta http-equiv="expires" content="0"> 
 <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
 <meta http-equiv="description" content="This is my page">
 <!--
 <link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" >
 -->
 </head>
 
 <body>
 <h1><a href="/Paging/Page/page?index=1" rel="external nofollow" >1</a></h1>
 <h1><a href="/Paging/Page/page?index=2" rel="external nofollow" >2</a></h1>
 <h1><a href="/Paging/Page/page?index=3" rel="external nofollow" >3</a></h1>
 
 <c:if test="${!empty list }">
 <c:forEach items="${list}" var="list">
 
 ${list.name}
 ${list.adderss}
 
 
 
     </c:forEach>
 </c:if>
 



 </body>
</html>

因為是簡單例子所以界面就很簡陋了。

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
