spring + hibernate + annotation 简单整合

spring + hibernate + annotation 简单整合直接整个例子出来，以便以后查看。1、pom.xml

更详细的介绍可以看：http://blog.csdn.net/qiantujava/article/details/40582569

直接整个例子出来，以便以后查看。

1、pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </build>
</project>

2、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:context="http://www.springframework.org/schema/context"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd">

  </bean>
  
	<!-- 配置sessionFactory -->  
	<bean id="sessionFactory"

	         <prop key="hibernate.format_sql">true</prop>
	        </props>
	    </property>
	</bean>
		
</beans>

3、User.java

package com.qiantu.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;

@Entity
@Table(name="_user")
public class User {
	private int id;
	private String name;
	private String password;
	
	public User() {
		super();
	}

	public User(String name, String password) {
		super();
		this.name = name;
		this.password = password;
	}

	@Id
	@GeneratedValue(generator="increment")
	@GenericGenerator(name="increment", strategy = "increment")
	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 getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
}

4、UserServiceIfTest.java

package com.qiantu.service;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.qiantu.model.User;

public class UserServiceIfTest {

	@Test
	public void test() {
		ApplicationContext ctx = 
				new FileSystemXmlApplicationContext("src/main/webapp/WEB-INF/applicationContext.xml");
		
		SessionFactory sessionFactory = (SessionFactory) ctx.getBean("sessionFactory");
		
		Session session = sessionFactory.openSession();
		session.beginTransaction();
		
		session.save(new User("linzhiquan", "9999"));
		
		User u = (User) session.get(User.class, 1);
		System.out.println(u.getId());
		System.out.println(u.getName());
		System.out.println(u.getPassword());
		
		session.getTransaction().commit();
		session.close();
		
		sessionFactory.close();
	}

}

要现在数据库里面创建一个数据库 to_other 。
