博文学习重点:

第四种方式:使用tx标签配置的拦截器

<?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" />

    <bean id="sessionFactory"  
            class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
        <property name="configLocation" value="classpath:hibernate.cfg.xml" />  
        <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
    </bean>  

    <!-- 定义事务管理器(声明式的事务) -->  
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>
    
    <aop:config>
        <aop:pointcut id="interceptorPointCuts"
            expression="execution(* com.bluesky.spring.dao.*.*(..))" />
        <aop:advisor advice-ref="txAdvice"
            pointcut-ref="interceptorPointCuts" />        
    </aop:config>      
</beans>

  

第五种方式:全注解

<?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"  
            class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  
        <property name="configLocation" value="classpath:hibernate.cfg.xml" />  
        <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" />
    </bean>  

    <!-- 定义事务管理器(声明式的事务) -->  
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" 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();
    }
    
    
}
