（一） 封装一个bean方法
package com.seecen.ssm.pojo;
import java.util.List;
/**
* Author: CalcYu
* Date: 2018/5/18
*/
public class Page {
/**
* 传递查询条件
*/
private A condition;
public A getCondition() {
return condition;
}
public void setCondition(A condition) {
this.condition = condition;
}
private List list;
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
/**
* 某张表的总记录数
*/
private Integer total;
/**
* 当前页数
*/
private Integer currentPage = 1;
/**
* 每页显示多少条记录
*/
private Integer pageSize = 10;
/**
* SQL分页的开始位置
*
* @return
*/
public Integer getStart() {
return (currentPage - 1) * pageSize;
}
/**
* SQL分页的结束位置
*
* @return
*/
public Integer getEnd() {
return currentPage * pageSize;
}
public Integer getTotalPage() {
return (int) Math.ceil(total * 1.0 / pageSize);
}
public Integer getTotal() {
return total;
}
public void setTotal(Integer total) {
this.total = total;
}
public Integer getCurrentPage() {
return currentPage;
}
public void setCurrentPage(Integer currentPage) {
this.currentPage = currentPage;
}
public Integer getPageSize() {
return pageSize;
}
public void setPageSize(Integer pageSize) {
this.pageSize = pageSize;
}
}
（二）Service
/**
* 创建一个订单
* @return
*/
public boolean addOrder(Order order);
/**
* 订单表的分页查询
* @param page
* @return
*/
public Page findOrdersByPage(Page page);
《*》ServiceImpl
@Autowired
private OrderMapper orderMapper;
public boolean addOrder(Order order) {
return orderMapper.insert(order) > 0;
}
public Page findOrdersByPage(Page page) {
if(page!=null){
page.setList(orderMapper.selectByExample(null));
page.setTotal(orderMapper.countByExample(null));
return page;
}
return null;
}
（三）Controller
@RequestMapping("/list")
public String list(Integer currentPage,Tclass tclass, Model model){
Page
if (currentPage!=null){
page.setCurrentPage(currentPage);
}
if (tclass!=null){
page.setCondition(tclass);
}
List
page = tclassService.findTclassByPage(page);
model.addAttribute("l",list);
model.addAttribute("p",page);
return "classfond/list";
}
//或者
@RequestMapping("")
public String list(Model model) {
Page
page = orderService.findOrdersByPage(page);
model.addAttribute("p", page);
return "order/list";
}
（四）jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
（HTML页面）
onclick="daiban(parseInt($('#pageIndex').html())+1>parseInt($('#pageCount').html())?parseInt($('#pageCount').html()):parseInt($('#pageIndex').html())+1)">下一页
onclick="daiban(parseInt($('#pageCount').html()))">尾页
当前第1页/共 id="pageCount" color="red">0页
