spring使用编程式事务

一、现在配置文件中声明一个事务的bean

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">    <property name="dataSource" ref="dataSource"/></bean>

二、在程序中直接使用transactionManager

//获取PlatformTransactionManager;PlatformTransactionManager transManager = (PlatformTransactionManager) context.getBean("transactionManager");//定义TransactionDefinition;DefaultTransactionDefinition transDef = new DefaultTransactionDefinition();//定义Transaction传播行为；transDef.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);//开始一个Transaction;TransactionStatus ts = transManager.getTransaction(transDef);transManager.commit(ts);
