SPring事务怎么写配置过得怎么写到方法里面

Question

一个方法同时实现一个修改和新增数据。某一个失败就事务回滚。一下是方法和事务配置：
public void updateSteelTagCheckingConfirm(String steelTagId,String recReviseTime,String status,String recRevisor) throws Exception
{
List list = steelPipeLabelDao.querySteelTagChecking();
SteelTagCheckingModel steelTagCheckingModel = (SteelTagCheckingModel) list.get(0);
steelTagCheckingModel.setId(null);
steelTagCheckingModel.setRecCreateTime(new Date());
steelTagCheckingModel.setRecReviseTime(new Date());
steelTagCheckingModel.setStatus(status);
steelTagCheckingModel.setRecRevisor(recRevisor);
steelPipeLabelDao.querySteelTagCheckingConfirm(steelTagId);//修改
steelPipeLabelDao.insertSteelTagCheckingConfirm(steelTagCheckingModel);//新增

}

以下是SPring事务配置

楼主如果一点概念都没有，建议先了解下底层的事物管理机制。
[code="java"]
try{
begin trans
update a
add b
trans.commit()
}catche(e){
trans.rollback()
}
[/code]
我们现在使用spring的事物管理，实际是使用AOP的横切概念， 也就是把那些事务管理部分剥离掉
