Spring事务配置方式五使用注解

<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.bluesky" />    <tx:annotation-driven transaction-manager="transactionManager"/>    <bean id="sessionFactory"              value="classpath:hibernate.cfg.xml" />          <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />    bean>            <bean id="transactionManager"        ref="sessionFactory" />    bean>    beans>

此时在DAO上需加上@Transactional注解，如下：

?

package com.bluesky.spring.dao;import java.util.List;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import org.springframework.stereotype.Component;import com.bluesky.spring.domain.User;@Transactional@Component("userDao")public class UserDaoImpl extends HibernateDaoSupport implements UserDao {    public List<User> listUsers() {        return this.getSession().createQuery("from User").list();    }        java.net/Images/dot.gif" />}
