首先bean.xml文件配置如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-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/tx 
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
	<context:annotation-config />
	<context:component-scan base-package="com.bjsxt" />

	<!-- 
		<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		
		
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/spring" />
		<property name="username" value="root" />
		<property name="password" value="bjsxt" />
		</bean>
	-->

	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:jdbc.properties</value>
		</property>
	</bean>

	<bean id="dataSource" destroy-method="close"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName"
			value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="annotatedClasses">
			<list>
				<value>com.bjsxt.model.User</value>
				<value>com.bjsxt.model.Log</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
	</bean>

	<bean id="txManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	
	<tx:annotation-driven transaction-manager="txManager"/>
	



</beans>


然后在service业务逻辑层相应的业务逻辑方法前加Annotation   @Transaction     注意不要加载Dao层,因为service层可能需要多个dao操作多个表,分开进行事务处理,必然不能同步:

@Component("userService")
public class UserService {
	
	private UserDAO userDAO;
	private LogDAO logDAO;
	
	public void init() {
		System.out.println("init");
	}
	
	public User getUser(int id) {
		return null;
	}
	
	@Transactional(readOnly=true)
	public void add(User user) {
		
			userDAO.save(user);
			Log log = new Log();
			log.setMsg("a user saved!");
			logDAO.save(log);
		
	}
	public UserDAO getUserDAO() {
		return userDAO;
	}
	
	@Resource(name="u")
	public void setUserDAO( UserDAO userDAO) {
		this.userDAO = userDAO;
	}
	

	
	public LogDAO getLogDAO() {
		return logDAO;
	}
	
	@Resource
	public void setLogDAO(LogDAO logDAO) {
		this.logDAO = logDAO;
	}

	public void destroy() {
		System.out.println("destroy");
	}
}
