private GoodsDao dao;
@Transactional

Object savepoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();
dao.save(entity);
TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savepoint);
return true;

Answer 1

dao.save(entity);，，只有一个操作的话，，测试事务回滚，，，不合适吧，，，

在下面再放一个错误的操作 ，，看看上面这个能不能save
