Spring事务管理

1 声明式事务 手动回滚事务

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

2 同一个事务里面部分回滚

        Object savePoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();
        TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savePoint);

3 异步线程事务在主线程事务提交后执行

        TransactionSynchronizationManager.registerSynchronization(new TransactionSynchronization() {
            @Override
            public void afterCommit() {
                TransactionSynchronization.super.afterCommit();
                //123
            }
        });

4 lambada事务

        transactionTemplate.execute(transactionStatus -> {
            //todo 123
            return null;
        });
