关于spring @Transactional手动回滚事务

1.鸡肋式回滚

TransactionAspectSupport.currentTransactionStatus().setRollbackonly() //只能在回滚时添加一些自己的逻辑，无法再次插入、更新、删除任何数据库的记录（即便代码顺序在setRollbackOnly之后，都会被回滚）；

2.设置部分回滚则可以再次尝试插入、更新、删除，甚至重复回滚前的操作都可以成功

Object savePoint = null;
    try {
        savePoint =         TransactionAspectSupport.currentTransactionStatus().createSavepoint();
       
    }catch (Exception e){       TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savePoint);
    }

3.全面替代@Tranactional，代之以注入DataSourceTransactionManager和TransactionDefinition，也能再次插入、更新、删除

@Autowired
DataSourceTransactionManager dataSourceTransactionManager;
@Autowired
TransactionDefinition transactionDefinition;

TransactionStatus transactionStatus = dataSourceTransactionManager.getTransaction(transactionDefinition);

手动提交事务
dataSourceTransactionManager.commit(transactionStatus);//提交
手动回滚事务
dataSourceTransactionManager.rollback(transactionStatus);//回滚
