本篇文章主要介绍了"Spring事物配置的五种方式",主要涉及到Spring事物配置的五种方式方面的内容,对于Spring事物配置的五种方式感兴趣的同学可以参考一下。

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DataSource、TransactionManager和代理机制这三部分,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"

    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"

    <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"?>
