Spring事物设置回滚点

    @Transactional    @RequestMapping("/show")    public String show(){        userService.addUser();        Object savePoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();        userService.addUser();        TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savePoint);        return null;    }

使用Object savePoint = TransactionAspectSupport.currentTransactionStatus().createSavepoint();
设置回滚点，使用TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(savePoint);回滚到savePoint。
