 前段时间对Spring的事务配置做了比较深入的研究,在此之间对Spring的事务配置虽说也配置过,但是一直没有一个清楚的认识。通过这次的学习发觉Spring的事务配置只要把思路理清,还是比较好掌握的。

   

总结如下:

   

Spring配置文件中关于事务配置总是由三个组成部分,分别是DataSourceTransactionManager代理机制这三部分,无论哪种配置方式,一般变化的只是代理机制这部分。

   

DataSource、TransactionManager这两部分只是会根据数据访问方式有所变化,比如使用Hibernate进行数据访问时,DataSource实际为SessionFactory,TransactionManager的实现为HibernateTransactionManager。

 

具体如下图:


 

根据代理机制的不同,总结了五种Spring事务的配置方式,配置文件如下:

   

第一种方式:每个Bean都有一个代理

<?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"
    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"
>

   
<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>
   
   
<!-- 配置DAO -->
   
<bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<bean id="userDao" 
        class
="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> 
          
<!-- 配置事务管理器 --> 
          
<property name="transactionManager" ref="transactionManager" />    
       
<property name="target" ref="userDaoTarget" /> 
        
<property name="proxyInterfaces" value="com.bluesky.spring.dao.GeneratorDao" />
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes"> 
           
<props> 
               
<prop key="*">PROPAGATION_REQUIRED</prop>
           
</props> 
       
</property> 
   
</bean> 
</beans>

   

 

第二种方式:所有Bean共享一个代理基类

<?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"
    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"
>

   
<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>
   
   
<bean id="transactionBase" 
            class
="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" 
            lazy-init
="true" abstract="true"> 
       
<!-- 配置事务管理器 --> 
       
<property name="transactionManager" ref="transactionManager" /> 
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes"> 
           
<props> 
               
<prop key="*">PROPAGATION_REQUIRED</prop> 
           
</props> 
       
</property> 
   
</bean>   
  
   
<!-- 配置DAO -->
   
<bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<bean id="userDao" parent="transactionBase" > 
       
<property name="target" ref="userDaoTarget" />  
   
</bean>
</beans>

 

 

第三种方式:使用拦截器

<?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"
    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"
>

   
<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> 
  
   
<bean id="transactionInterceptor" 
        class
="org.springframework.transaction.interceptor.TransactionInterceptor"> 
       
<property name="transactionManager" ref="transactionManager" /> 
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes"> 
           
<props> 
               
<prop key="*">PROPAGATION_REQUIRED</prop> 
           
</props> 
       
</property> 
   
</bean>
     
   
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> 
       
<property name="beanNames"> 
           
<list> 
               
<value>*Dao</value>
            </list> 
       
</property> 
       
<property name="interceptorNames"> 
           
<list> 
               
<value>transactionInterceptor</value> 
           
</list> 
       
</property> 
   
</bean> 
 
   
<!-- 配置DAO -->
   
<bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
</beans>

 

 

第四种方式:使用tx标签配置的拦截器(常用)

<?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.xy.BaseServiceImpl.*(..))" />
       
<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();
    }
   
   
}
