2016-10-18 09:40 141 查看

附源码下载（底）。实现了登录，查询分页，文件上传等基本功能

page.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>测试</title>
</head>

<table>
<c:forEach items="${page.data}" var="us" varStatus="status">
<tr>
<td><input type="checkbox" name="id" value="${user.id}" /></td>
<td>${us.id}</td>
<td>${us.username}</td>
<td>${us.password}</td>
<td>${us.age}</td>

</tr>
</c:forEach>
</table>

<div>
共<span >${page.count}</span>个记录
当前第<span >${page.pageNow}</span>页

<a href="${page.firtpage}" >首页</a>
<a href="${page.prevpage}" >上一页</a>

<a href="${page.nextpage}">下一页</a>
<a href="${page.lastpage}" >尾页</a>
</div>
<body>

</body>
</html>


控制器PageController.java。测试可以把user对象数据写在内存中。不用service

package com.cn.uuu.controller;

import java.util.List;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

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

import com.cn.uuu.pojo.Pages;
import com.cn.uuu.pojo.User;
import com.cn.uuu.service.UserService;

/**
* @author chuck
*
*/
@Controller
@RequestMapping("/page")
public class PageController {
@Resource(name="userServiceImpl")
private UserService userService;

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService = userService;
}

@RequestMapping(value="/listpage.do", method = RequestMethod.GET)
public String toIndex(HttpServletRequest request,Model model,Pages page){

4000
String queryString = request.getQueryString();
System.out.println(queryString);

List data=userService.selectAll();
int count=userService.selectCount();

//(pageNow - 1) * pageSize------------pageNow * pageSize 分页的始末
page.setCount(count);
page.setPageSize(3);
int index1=page.pageNow*3-3;//6
int index2=index1+3;//9
if (index2>count) {
index2=count;
}
if (index1<0) {
index1=0;
}
if (index1>=0 && index1< count  ) {
page.setData(data.subList(index1, index2));
}
//          page.setData(data.subList(5, 6));
page.setNextpage("http://localhost:8080/page/listpage.do?pageNow="+(page.getPageNow()+1));
page.setPrevpage("http://localhost:8080/page/listpage.do?pageNow="+(page.getPageNow()-1));
System.out.println(page.getData().get(0).toString());
model.addAttribute("page", page);
return "page";
}
}


model
