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

为什么交易没有回滚?
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
。
