一个方法内如何让某些事务回滚，一部分不回滚

一、利用保存点

Object savepoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();

TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savepoint);

二、利用多线程

@Transactional(rollbackFor = Exception.class)
public void test(){
    try {
        RefundEntity byId = refundService.getById(35);
        byId.setStatus("oo");
        refundService.updateById(byId);
        System.out.println(1/0);
    }catch (Exception e){
        e.printStackTrace();
        taskExecutor.execute(()->{operationLogService.OASave(35,RefundOperationEnum.OA_REJECT,"OK");});
        throw new BizException("不和发");
    }
}

不回滚的事务写到finally方法里（此种方法不好使）

@Transactional(rollbackFor = Exception.class)
public void test(){
    try {
        RefundEntity byId = refundService.getById(35);
        byId.setStatus("hh");
        refundService.updateById(byId);
        System.out.println(1/0);
    }catch (Exception e){
        e.printStackTrace();
        //执行顺序一
        throw new BizException("不和发");
    }finally {
        //执行顺序二
        operationLogService.OASave(35,RefundOperationEnum.OA_REJECT,"OK");
    }
}

原因： 方法执行顺序：

1、开启事务（aop）

2、catch住异常

3、向上抛异常

4、执行finally方法

5、回滚或提交事务(aop)
