DataSourceTransactionManager手动提交事务和回滚事务

三个步骤：

1、初始化事务

2、事务提交

3、如果异常，事务回滚

代码示例：

 

@Autowired
private DataSourceTransactionManager dataSourceTransactionManager;
public void process()
{
     TransactionStatus status = dataSourceTransactionManager.getTransaction(new DefaultTransactionDefinition(TransactionDefinition.PROPAGATION_REQUIRES_NEW));
         //dosomething
         dataSourceTransactionManager.commit(status);
}catch (Exception e) {
        dataSourceTransactionManager.rollback(status);
        //dosometing
            }
