spring-framework-3.2.4.RELEASE
hibernate-release-4.2.5.Final
jdk1.7spring
要使用Spring3整合Hibernate4須要再添加如下包sql
1.---- spring-orm-3.2.4.RELEASE.jar
2.---- spring-dao-2.0.7.jar(Spring裏沒有提供,須要到網上下載)數據庫
在要用到hibernate的類中添加SessionFactory屬性和相應的set方法session
public class StudentDaoImpl implements IStudentDao { //SessionFactory 在包org.hibernate內 private SessionFactory sessionFactory; public void save(Student student) { Session session = sessionFactory.getCurrentSession(); session.beginTransaction(); session.save(student); session.getTransaction().commit(); System.out.println("save:"+student.getName()); } //爲SessionFactory添加set方法,Spring才能爲其注入 public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } }
在配置文件中添加SessionFactory 的baenoracle
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <!-- 添加sessionFactory bane ,注意,該類是Spring提供的 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 注入Hibernate 配置文件路徑,前面要加上 classpath:--> <property name="configLocation" value="classpath:hibernate.cfg.xml"/> </bean> <bean id="studentDao" class="com.startspring.dao.impl.StudentDaoImpl"> <!-- 把sessionFactory 注入給studentDao --> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="studentService" class="com.startspring.service.impl.StudentServiceImpl"> <property name="studentDao" ref="studentDao" /> </bean> <bean id="start" class="com.startspring.Start"> <property name="studentService" ref="studentService" /> </bean> </beans>

若是要使用數據源:this
1.先把數據源相關的包導入到項目。spa
2.在Spring配置文件中添加數據源的bean。hibernate
3.把數據源 bean 注入到sessionFactory的dataSource屬性。
(關於 Spring 注入數據源:http://www.cnblogs.com/likailan/p/3459776.html)
Spring配置文件 以下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <!-- 數據源 --> <bean id="dataSource" destroy-method="close" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="oracle.jdbc.OracleDriver" /> <property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:ORCL" /> <property name="user" value="hib" /> <property name="password" value="hib" /> </bean> <!-- 添加sessionFactory bane ,注意,該類是Spring提供的 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 注入Hibernate 配置文件路徑,前面要加上 classpath:--> <property name="configLocation" value="classpath:hibernate.cfg.xml"/> <!-- 把數據源 bean 注入到sessionFactory的dataSource屬性 --> <property name="dataSource" ref="dataSource"/> </bean> <bean id="studentDao" class="com.startspring.dao.impl.StudentDaoImpl"> <!-- 把sessionFactory 注入給studentDao --> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="studentService" class="com.startspring.service.impl.StudentServiceImpl"> <property name="studentDao" ref="studentDao" /> </bean> <bean id="start" class="com.startspring.Start"> <property name="studentService" ref="studentService" /> </bean> </beans>
如今數據庫鏈接交由數據源來管理。能夠把 hibernate.cfg.xml 文件中的connection.driver_class、connection.username等屬性去掉了。
--------------------------------------------------------------------------------------------------------------
經過注入的方式爲SessionFactory注入hibernate的配置信息,從而省去hibernate配置文件
Spring配置文件 以下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <!-- 數據源 --> <bean id="dataSource" destroy-method="close" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="oracle.jdbc.OracleDriver" /> <property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:ORCL" /> <property name="user" value="hib" /> <property name="password" value="hib" /> </bean> <!-- 添加sessionFactory bane ,注意,該類是Spring提供的 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 把數據源 bean 注入到sessionFactory的dataSource屬性 --> <property name="dataSource" ref="dataSource"/> <!-- hibernate的基本配置,如:方言,是否顯示sql等 --> <property name="hibernateProperties"> <props> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> </props> </property> <!-- 引入映射文件,若是有多個能夠繼續添加 <value> --> <property name="mappingLocations"> <list> <value>com/startspring/entrty/Student.hbm.xml</value> </list> </property> </bean> <bean id="studentDao" class="com.startspring.dao.impl.StudentDaoImpl"> <!-- 把sessionFactory 注入給studentDao --> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="studentService" class="com.startspring.service.impl.StudentServiceImpl"> <property name="studentDao" ref="studentDao" /> </bean> <bean id="start" class="com.startspring.Start"> <property name="studentService" ref="studentService" /> </bean> </beans>
如今能夠把 hibernate.cfg.xml 文件刪除了。
原來Spring的配置文件中<property name="configLocation" value="classpath:hibernate.cfg.xml"/>這行代碼也能夠刪去了。
----------------------------------------------------------------------------------------------------------
Spring2.x整合Hibernate和Spring3.x版基本一致,但要注意如下幾點:
1. Spring2.x只支持Hibernate3 ,並不支持Hibernate4
2. 整合 Hibernate3 使用的SessionFactory Bean 是:org.springframework.orm.hibernate3包下的LocalSessionFactoryBean而不是org.springframework.orm.hibernate4.LocalSessionFactoryBean(Spring3整合hibernate3也是)
3. 導入包時注意刪除相同的包!(優先刪除版本低的)
