spring 整合hibernate

标签：spring   hibernate   

      在applicationContext.xml里配置数据源和SessionFactory,SessionFactory引入数据源。在dao层，通过SessionFactory可以获取session，进行持久化操作。

1 结合注解的形式整合hibernate：

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"
	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
		 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
		http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
		http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-2.5.xsd">
	<context:component-scan base-package="com.*" />
	<context:annotation-config />
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:c3p0.properties</value>
		</property>
	</bean>
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${driverClass}"></property>
		<property name="jdbcUrl" value="${jdbcUrl}"></property>
		<property name="user" value="${user}"></property>
		<property name="password" value="${password}"></property>
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="annotatedClasses">
			<list>
				<value>com.entity.Student</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
			</props>			
		</property>

	</bean>
</beans>

持久化类：

package com.entity;

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

@Entity
public class Student {
	@Id
	@GeneratedValue
	private Integer studentId;
	private String studentName;
	public Integer getStudentId() {
		return studentId;
	}
	public void setStudentId(Integer studentId) {
		this.studentId = studentId;
	}
	public String getStudentName() {
		return studentName;
	}
	public void setStudentName(String studentName) {
		this.studentName = studentName;
	}
	
}

dao层：

package com.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import com.entity.Student;
@Repository(value="userDao")
public class UserDao {	
	private SessionFactory sessionFactory;
	
	
	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	@Resource
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}


	public void save(){
		try {			
			Session session=sessionFactory.openSession();
			session.beginTransaction();
			Student s=new Student();			
			s.setStudentName("hi");
			session.save(s);
			session.getTransaction().commit();
			session.close();
			System.out.println("ok");
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		
	}
}

2 利用配置的形式整合Hibernate:

持久化类：

package com.entity;

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

//@Entity
public class Student {
//	@Id
//	@GeneratedValue
	private Integer studentId;
	private String studentName;
	public Integer getStudentId() {
		return studentId;
	}
	public void setStudentId(Integer studentId) {
		this.studentId = studentId;
	}
	public String getStudentName() {
		return studentName;
	}
	public void setStudentName(String studentName) {
		this.studentName = studentName;
	}
	
}

ORM映射student.hbm.xml配置：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.entity">

    <class name="Student" table="TAB_STUDENT">
        <id name="studentId" column="s_id">
            <generator class="native"/>
        </id>       
        <property name="studentName" column="s_name" not-null="true"/>       
    </class>

</hibernate-mapping>

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"

		http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-2.5.xsd">
	<!-- <context:component-scan base-package="com.*" />
	<context:annotation-config /> -->
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

			<value>classpath:c3p0.properties</value>
		</property>
	</bean>
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${driverClass}"></property>
		<property name="jdbcUrl" value="${jdbcUrl}"></property>
		<property name="user" value="${user}"></property>
		<property name="password" value="${password}"></property>
	</bean>

	<!-- <bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="annotatedClasses">

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

		</property>

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

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

		<property name="hibernateProperties">

				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
			</props>			
		</property>
	</bean>
	<bean id="userDao" class="com.dao.UserDao">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<bean id="userService" class="com.service.UserService">
		<property name="userDao" ref="userDao"></property>
	</bean>
</beans>

dao层：

package com.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import com.entity.Student;
//@Repository(value="userDao")
public class UserDao {	
	private SessionFactory sessionFactory;
	
	
	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

//	@Resource
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}


	public void save(){
		try {			
			Session session=sessionFactory.openSession();
			session.beginTransaction();
			Student s=new Student();			
			s.setStudentName("hi");
			session.save(s);
			session.getTransaction().commit();
			session.close();
			System.out.println("ok");
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		
	}
}

service层：

package com.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.dao.UserDao;
//@Service
public class UserService {
	private UserDao userDao;

	public UserDao getUserDao() {
		return userDao;
	}
//	@Resource(name="userDao")
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	public void save(){
		userDao.save();
	}
}

测试：

package com.aop;

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

import com.service.UserService;

public class Test {

	public static void main(String[] args) {
		ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
		UserService uc=(UserService) ac.getBean("userService");
		uc.save();
		
	}

}
