@Transaction不会在春季回滚交易

我正在使用Spring Jdbc和@Transaction批注作为在数据库中插入数据的方法。代码片段是:

@Transactional(rollbackForClassName={"Exception"})
    public PreBookingResponse saveData(Tip trip, HttpServletRequest request) throws Exception {
        PreBookingResponse preBookingResponse = null;
        try {
            String bookingRefNo = "89";
            trip.setBookingRefNo(bookingRefNo);
            MinimumUserProfile userProfile = JwtService.getUserFromToken(request);
            String userId = userProfile.getUserId();

            if (tripDao.saveTripData(trip, userId)) {
                preBookingResponse = new PreBookingResponse(0, "");
                preBookingResponse.setBookingRefNo(bookingRefNo);
                preBookingResponse.setSearchId(trip.getSearchId());
                preBookingResponse.setId(trip.getId());
            }
        }catch(Exception e)
        {
            String errorMsg = "Error occur while saving trip data due to: " + e.getMessage();
            log.error(errorMsg);
            preBookingResponse = new PreBookingResponse(2, errorMsg);
            preBookingResponse.setBookingRefNo(trip.getBookingRefNo());
            preBookingResponse.setSearchId(trip.getSearchId());
            throw e;
        }
        return preBookingResponse;
    }

内部函数tripDao.saveTripData(trip, userId)我在多个表中输入数据。当插入数据时发生任何异常时,所有插入操作都应该回滚,但它们不会。

我的spring-config.xml是(我从另一个项目导入):

为什么交易没有回滚?

2 个答案:

答案 0 :(得分:0)

此代码不会回滚事务becoz异常不会被抛回到方法中。

@Transactional(rollbackForClassName = {“Exception”})表示在从此方法返回Exception时回滚事务。但在您的情况下,您正在捕获异常并返回正确的响应,因此事务将被提交。 Spring会在此方法调用周围创建一个AOP事务建议,如果方法正常返回则会成功提交,如果从此方法抛出异常,则会回滚。

要回滚,要么从此方法抛出异常,要么将try块中的代码移动到另一个方法,并使用该方法注释该方法 @Transactional(rollbackForClassName = { “异常”})

您需要在defaultAutoCommit中停用dataSource
