ZK7+Spring4+Hibernate4框架整合并实现基本查询

框架环境组件版本：ZK 7.0.0 、Spring 4.0.6、Hibernate 4.2.2 。

第一次将这三个版本搭配到一起，组合的过程中，解决了很多次的jar包冲突，最终以下jar包可以完美契合。

ZK7所需jar包：点击下载ZK7所需jar包

Spring4所需jar包：点击下载Spring4所需jar包

Hibernate4所需jar包：点击下载Hibernate4所需jar包

下面开始整合，开发工具用的是Eclipse，数据库用的是MySQL：

1、新建ZK Project ，/WEB-INF/lib下会自动出现一些ZK项目所必需的jar包，不用管它。将下载的所有jar包都导入lib文件夹，然后Build Path。

2、在/WEB-INF下新建Spring的配置文件：applicationContext.xml，文件详细内容如下（注意修改数据库的参数）：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>
<bean id="factory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

</property>
<property name="hibernateProperties">

</prop>
<prop key="hibernate.show_sql">

</property>
<property name="dataSource">

<bean id="userDao" class="com.zsh.dao.UserDao">

</property>
</bean>
<bean id="userService" class="com.zsh.service.impl.UserServiceImpl">
<property name="ud">
<ref bean="userDao"/>
</property>
</bean>
</beans>

3、修改/WEB-INF下，ZK项目的配置文件：web.xml，详细内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

<listener>
<description>Used to cleanup when a session is destroyed</description>
<display-name>ZK Session cleaner</display-name>
<listener-class>org.zkoss.zk.ui.http.HttpSessionListener</listener-class>
</listener>
<servlet>

<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
<welcome-file>index.zul</welcome-file>
</welcome-file-list>
</web-app>

4、新建Hibernate的配置文件：User.hbm.xml，详细内容如下：

<?xml version="1.0"?>
<!-- User.hbm.xml -->
<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping
package="com.zsh.model">
<class name="User" table="user" lazy="false">
<id name="id" type="int">
<generator class="increment"/>
</id>
<property name="name" />
<property name="surname"/>
</class>
</hibernate-mapping>

5、实体类：User.java，详细代码如下：

package com.zsh.model;

public class User {
private int id ;
private String name;
private String surname;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
}

6、业务层接口：UserService.java，详细代码如下：

package com.zsh.service;

import java.util.List;

import com.zsh.model.User;

public interface UserService {

public List getAllUsers();

}

7、业务层的定位类：ServiceLocator.java，详细代码如下：

package com.zsh.service;

import org.hibernate.SessionFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zsh.service.UserService;

public class ServiceLocator {

private static ApplicationContext ctx;

static {
ctx = new ClassPathXmlApplicationContext("../applicationContext.xml");
}

private ServiceLocator() {
}

public static SessionFactory getSessionFactory() {
return (SessionFactory) ctx.getBean("factory",SessionFactory.class);
}

public static UserService getUserManager() {
return (UserService) ctx.getBean("userService",UserService.class);
}
}

8、业务层实现类：UserServiceImpl.java，详细代码如下：

package com.zsh.service.impl;

import com.zsh.dao.UserDao;
import com.zsh.model.User;
import com.zsh.service.UserService;

import java.util.*;

public class UserServiceImpl implements UserService {

private UserDao ud;

public UserDao getUd() {
return ud;
}

public void setUd(UserDao ud) {
this.ud = ud;
}

public List getAllUsers() {
return this.ud.findAll(User.class);
}
}

9、持久层文件：UserDao.java，详细代码如下：

package com.zsh.dao;

import java.util.List;

import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
public class UserDao extends HibernateDaoSupport {
public void saveOrUpdate(Object ob) {
super.getHibernateTemplate().saveOrUpdate(ob);
}

public void delete(Object ob) {
super.getHibernateTemplate().delete(ob);
}

@SuppressWarnings("unchecked")
public Object find(Class clazz, Long id) {
Object ob =  super.getHibernateTemplate().load(clazz,id);
return ob;
}
@SuppressWarnings("unchecked")
public List findAll(Class clazz) {
List list = super.getHibernateTemplate().find(" from "+clazz.getName());
return list;
}

}

10、ZK的UI交互类：ListUser.java，详细代码如下：

package com.zsh.ui;

import com.zsh.service.ServiceLocator;
import java.util.*;
import com.zsh.service.UserService;
import com.zsh.model.User;
import org.zkoss.zul.Label;
import org.zkoss.zul.Listbox;
import org.zkoss.zul.Listcell;
import org.zkoss.zul.Listitem;

import com.zsh.model.User;
import com.zsh.service.UserService;

public class ListUser extends Listbox {

public void onCreate() {
UserService us = ServiceLocator.getUserManager();
Collection allUsers = us.getAllUsers();
Iterator it = allUsers.iterator();
while(it.hasNext()) {
User user = (User) it.next();
Long id = (long) user.getId();
String name = user.getName();
String surname = user.getSurname();

Listitem listitem = new Listitem();
listitem.setValue(id);
listitem.setParent(this);

Listcell nameCell = new Listcell(name);
nameCell.setParent(listitem);
Listcell surnameCell = new Listcell(surname);
surnameCell.setParent(listitem);
}
}
}

11、资源包根目录下的日志配置文件：log4j.properties，详细代码如下：

#  $Id: Action.java 502296 2007-02-01 17:33:39Z niallp $
#
#  Licensed to the Apache Software Foundation (ASF) under one
#  or more contributor license agreements.  See the NOTICE file

log4j.rootLogger = WARN, stdout

log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold = WARN
log4j.appender.stdout.Target   = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %d{ISO8601} %-5p [%F:%L] : %m%n

12、前台ZUL页面：index.zul，详细代码如下：

<!-- user.zul -->
<vbox>
<listbox id="userList" width="800px" rows="5" use="com.zsh.ui.ListUser">
<listhead>
<listheader label="Name"/>
<listheader label="Surname"/>
</listhead>
</listbox>
</vbox>

搭好之后，整个项目的目录结构是这个样子的：



That`s all.
