Spring boot 和 JPA 事务不起作用

Tom*_*rez 2 spring hibernate jpa spring-boot

我试图通过save在事务中运行多个方法来原子地保存许多实体，因此如果其中任何一个失败，所有这些都将被丢弃（回滚）。我尝试了很多东西，但似乎没有任何效果：

预订资源.java：

@RestController
public class BookingResource {

    @Autowired
    private ReservationRepository reservationRepository;

    @PostMapping("/booking")
    @Transactional(noRollbackFor=RuntimeException.class)
    public ResponseEntity<BookingResourceResponse> createReservtion(@RequestBody Reservation body) {
        //code...
        try {
            int day = 0;

            do {
                reservationRepository.save(new Reservation(..., day));
            }
            while(day <= LIMIT_VALUE);
            return buildResponse(HttpStatus.CREATED, new BookingResourceResponse(body));
        }
        catch(Exception e) {
            return buildResponse(HttpStatus.CONFLICT, new BookingResourceResponse("Some error here"));
        }
    }

那么，这里发生了什么？我该如何解决？我试图公开这些方法，改变交易政策，但没有任何效果。有解决方法吗？

谢谢！

这里发生了什么？

事务静默回滚，因为它已被标记为仅回滚。

当外部@Transactional方法调用内部@Transactional方法并且两者都在相同的物理 TX 下（例如两者都是Propagation.REQUIRED默认设置）时，就会发生这种情况。然后，当内部方法抛出异常时，它会将 TX 标记为需要回滚。但是，如果外部方法提交 TX ，则会发生此异常。这是设计的正常行为，因为内部方法说它要回滚，而外部方法说它要提交，它们相互矛盾。

在你的情况，具有内部方法@Transactional来自JpaRepository#save（这是春天的数据的当前设计）。如果其中发生异常并且您在外部方法（即BookingResource#createReservtion()）中捕获了所有异常，则会发生此异常。

解决方案

根据您的要求，您必须BookingResource#createReservtion()在捕获异常后重新抛出异常。还需要确保noRollbackForincreateReservtion()的@Transactional未设置为与重新抛出的异常相同的任何类型，以便发出您想要回滚而不是提交外部方法的信号，例如：

@PostMapping("/booking")
@Transactional
public ResponseEntity<BookingResourceResponse> createReservtion(@RequestBody Reservation body) {
    //code...
    try {
        int day = 0;
        do {
            reservationRepository.save(new Reservation(..., day));
        }
        while(day <= LIMIT_VALUE);
        return buildResponse(HttpStatus.CREATED, new BookingResourceResponse(body));
    }
    catch(Exception e) {
        throw new AppException(buildResponse(HttpStatus.CONFLICT, new BookingResourceResponse("Some error here")) , e);
    }
}
