在hibernate中使用uuid自动生成主键,使用uuid.hex会有一个警告信息出现,使用uuid2即可.好像是说什么不符合标准.

今天捣鼓了很久才把spring和hibernate给整合了.

首先是beans.xml这个玩意,使用的是hibernate最新的4.3.6,在网上找的是hibernate3的配置方式,出错了,把hibernate3改为hibernate4就可以了.之后还添加了一些依赖包.最后出现一个奇怪的问题,百度了几下,才知道spring3和hibernate4.1.7以上版本不兼容.下了spring4..0.0,还不行,又下了个hibernate4.1.6,这下终于是成功插入了.

后面又使用了C3P0连接池,导入了两个包,分别是c3p0-0.9.2.1.jar和mchange-commons-java-0.2.3.4.jar

代码如下:

以上是spring的配置文件beans.xml的配置

下面是User.hbm.xml模型的配置文件:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC        '-//Hibernate/Hibernate Mapping DTD 3.0//EN'        'http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd'><hibernate-mapping>    <class name="cn.mrz.demo.model.User" table="user">        <id name="id">          <!--<generator class="uuid.hex" />-->          <!-- WARN: HHH000409: Using org.hibernate.id.UUIDHexGenerator which does not generate IETF RFC 4122 compliant UUID values; consider using org.hibernate.id.UUIDGenerator instead           -->           <generator class="uuid2" />        </id>        <property name="username"></property><property name="password"></property><property name="email"></property><property name="joindate"></property>    </class></hibernate-mapping>

下面是模型,没啥好看的.

package cn.mrz.demo.model;import java.util.Date;public class User {private String Id;private String Username;private String Password;private String Email;private Date Joindate;public String getId() {return Id;}public void setId(String id) {Id = id;}public String getUsername() {return Username;}public void setUsername(String username) {Username = username;}public String getPassword() {return Password;}public void setPassword(String password) {Password = password;}public String getEmail() {return Email;}public void setEmail(String email) {Email = email;}public Date getJoindate() {return Joindate;}public void setJoindate(Date joindate) {Joindate = joindate;}}

接口

package cn.mrz.demo.service;import java.util.List;import cn.mrz.demo.model.User;public interface UserService {public void save(User user);public void delete(String id);public void update(User user);public List<User> getUsers();}

实现类

package cn.mrz.demo.service.impl;import java.util.List;import javax.annotation.Resource;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.transaction.annotation.Transactional;import cn.mrz.demo.model.User;import cn.mrz.demo.service.UserService;public class UserServiceBean implements UserService {    @Resource     private SessionFactory sessionFactory;    @Transactional    public void save(User user) {// TODO Auto-generated method stubSession session = sessionFactory.getCurrentSession();session.persist(user);}@Overridepublic void delete(String id) {// TODO Auto-generated method stub}@Overridepublic void update(User user) {// TODO Auto-generated method stub}@Overridepublic List<User> getUsers() {// TODO Auto-generated method stubreturn null;}}

测试类:

package cn.mrz.demo.view;import java.util.Date;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.mrz.demo.model.User;import cn.mrz.demo.service.UserService;public class TestClass {public static void main(String[] args) {ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");UserService ps = (UserService) applicationContext.getBean("UserService");User user = new User();user.setEmail("1111");user.setUsername("1111");user.setPassword("1111");user.setJoindate(new Date());ps.save(user);}}
