一、这是SSH框架下的demo：
二、例子界面
三、然后建立一JavaBean类用来封装查询条件
package util;
/**
* 客户信息关系表的查询属性
* @author miao
*
*/
public class SearchProperties {
private int custNo;
private String custName;
private String custRegion;
private String custManagerName;
private String custLevelLabel;
public SearchProperties() {
super();
}
public SearchProperties(String custName, String custRegion,
String custManagerName, String custLevelLabel) {
super();
this.custName = custName;
this.custRegion = custRegion;
this.custManagerName = custManagerName;
this.custLevelLabel = custLevelLabel;
}
public SearchProperties(int custNo, String custName, String custRegion,
String custManagerName, String custLevelLabel) {
super();
this.custNo = custNo;
this.custName = custName;
this.custRegion = custRegion;
this.custManagerName = custManagerName;
this.custLevelLabel = custLevelLabel;
}
public int getCustNo() {
return custNo;
}
public void setCustNo(int custNo) {
this.custNo = custNo;
}
public String getCustName() {
return custName;
}
public void setCustName(String custName) {
this.custName = custName;
}
public String getCustRegion() {
return custRegion;
}
public void setCustRegion(String custRegion) {
this.custRegion = custRegion;
}
public String getCustManagerName() {
return custManagerName;
}
public void setCustManagerName(String custManagerName) {
this.custManagerName = custManagerName;
}
public String getCustLevelLabel() {
return custLevelLabel;
}
public void setCustLevelLabel(String custLevelLabel) {
this.custLevelLabel = custLevelLabel;
}
}
四、dao接口
package dao;
import java.util.List;
import util.SearchProperties;
import entity.CstCustomer;
/**
* 客户信息关系接口
*
* @author Ali
*
*/
public interface CstCustomerDao {
/**
* 查询总记录数
*/
public Integer findCount();
/**
* 查询有条件的总记录数
*/
public Integer countCustomerByProperties(SearchProperties condition);
/**
* 得到某条件的记录
*/
public List<CstCustomer> getCustomerByProperties(SearchProperties condition, int first, int max);
}
五、daoImpl类
package dao.impl;
import java.util.List;
import org.hibernate.criterion.DetachedCriteria;
import org.hibernate.criterion.MatchMode;
import org.hibernate.criterion.Restrictions;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import util.SearchProperties;
import dao.CstCustomerDao;
import entity.CstCustomer;
/**
* 客户信息关系实现类
*
* @author Ali
*
*/
public class CstCustomerDaoImpl extends HibernateDaoSupport implements CstCustomerDao {
/**
* 根据条件建立DetachedCriteria对象
*
* @param condition
* @return
*/
public DetachedCriteria createCriterionByProperties(SearchProperties condition) {
DetachedCriteria criteria = DetachedCriteria.forClass(CstCustomer.class);
// 客户编号
if (condition.getCustNo() != 0) {
criteria.add(Restrictions.eq("custNo", condition.getCustNo()));
}
// 客户名字
if (null != condition.getCustName() && !"".equals(condition.getCustName())) {
criteria.add(Restrictions.ilike("custName", condition.getCustName(),
MatchMode.ANYWHERE));
}
// 地区
if (null != condition.getCustRegion() && !"".equals(condition.getCustRegion())) {
criteria.add(Restrictions.ilike("custRegion", condition.getCustRegion(),
MatchMode.ANYWHERE));
}
// 客户经理
if (null != condition.getCustManagerName() && !"".equals(condition.getCustManagerName())) {
criteria.add(Restrictions.ilike("custManagerName", condition.getCustManagerName(),
MatchMode.ANYWHERE));
}
// 客户等级
if (null != condition.getCustLevelLabel() && !"".equals(condition.getCustLevelLabel())) {
criteria.add(Restrictions.eq("custLevelLabel", condition.getCustLevelLabel()));
}
return criteria;
}
/**
* 查询总记录数
*/
public Integer findCount() {
return super.getHibernateTemplate().loadAll(CstCustomer.class).size();
}
/**
* 得到某条件的记录
*
* @param condition
* @param first
* @param max
* @return
*/
@SuppressWarnings("unchecked")
public List<CstCustomer> getCustomerByProperties(SearchProperties condition, int first, int max) {
DetachedCriteria detachedCriteria = createCriterionByProperties(condition);
return super.getHibernateTemplate().findByCriteria(detachedCriteria, first, max);
}
/**
* 查询有条件的总记录数
*/
public Integer countCustomerByProperties(SearchProperties condition) {
DetachedCriteria detachedCriteria = createCriterionByProperties(condition);
return super.getHibernateTemplate().findByCriteria(detachedCriteria).size();
}
}
六、biz接口
package biz;
import java.util.List;
import util.SearchProperties;
import entity.CstCustomer;
/**
* 客户信息关系业务接口
*
* @author miao
*
*/
public interface CstCustomerBiz {
/**
* 查询总记录数
*/
public Integer findCount();
/**
* 查询有条件的总记录数
*/
public Integer countCustomerByProperties(SearchProperties condition);
/**
* 得到某条件的记录
*/
public List<CstCustomer> getCustomerByProperties(SearchProperties condition, int first, int max);
}
七、bizImpl类
package biz.impl;
import java.util.List;
import util.SearchProperties;
import biz.CstCustomerBiz;
import dao.CstCustomerDao;
import entity.CstCustomer;
/**
* 客户信息关系业务实现类
*
* @author Ali
*
*/
public class CstCustomerBizImpl implements CstCustomerBiz {
// 调用dao
private CstCustomerDao cstCustomerDao;
// set注入
public void setCstCustomerDao(CstCustomerDao cstCustomerDao) {
this.cstCustomerDao = cstCustomerDao;
}
/**
* 查询总记录数
*/
public Integer findCount() {
return cstCustomerDao.findCount();
}
public Integer countCustomerByProperties(SearchProperties condition) {
return cstCustomerDao.countCustomerByProperties(condition);
}
public List<CstCustomer> getCustomerByProperties(SearchProperties condition, int number, int size) {
int first = (number - 1) * size;
return cstCustomerDao.getCustomerByProperties(condition, first, size);
}
}
八、第一个页面。用来显示查询条件和转跳至action
<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<link type="text/css" rel="stylesheet" href="css/style.css" />
<sx:head />
</head>
<body>
<!-- 头部，查询条件 -->
<div class="page_title">客户信息管理</div>
<s:form method="post" action="search" id='sform' namespace="/" theme="simple">
<div class="button_bar">

<sx:submit cssClass="common_button" type="button" name="search" value="查询" targets="divCustomer" />
</div>
<table class="query_form_table">
<tr>
<th>客户编号</th>
<td>
<s:textfield name="custNo" id="custNo" />
</td>
<th>名称</th>
<td>
<s:textfield name="custName" id="custName"/>
</td>
<th>地区</th>
<td>
<!-- key是值,value是显示 -->

</td>
<th></th>
<td></td>
</tr>
</table>
</s:form>
<!-- struts2 的??? -->
<div class="data_list_table">
<!-- 显示分页数据 -->
<sx:div id="divCustomer" href="search.action">正在加载，请稍候...</sx:div>
</div>
</body>
</html>
九、第二个页面，用来显示数据和实现分页
<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

十、action的编写
