Spring boot 和 JPA 事务不起作用

Question

我试图通过在事务中运行多个 save 方法来自动保存许多实体，因此如果其中任何一个失败，所有实体都将被丢弃(回滚)。我尝试了很多方法，但似乎没有任何效果:

BookingResource.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"));
        }
    }

}

ReservationRepository.java:

public interface ReservationRepository extends JpaRepository<Reservation, Long> {

}

预订.java:

@Entity
public class Reservation {

    @Id
    @Column(name="reservation_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;
    private String uuid;
    private String email;
    private String name;
    @Column(name="last_name")
    private String lastName;
    @Column(unique=true)
    private LocalDate date;
    private LocalDate dateTo;

    public Reservation() {
        //blank
    }

    public Reservation(..., int day) {
        //...
    }
    //... getters and setters
}

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。有解决办法吗？

谢谢!

Answer 1

这里发生了什么？

Transaction silently rolled back because it has been marked as rollback-only.

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 下时(例如，两者都是 Propagation.REQUIRED)，就会发生这种情况code> 这是默认设置)。然后，当内部方法抛出异常时，它将将该 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。这是设计上的正常行为，因为内部方法说它要回滚，但外部方法说它要提交，这是相互矛盾的。

在你的例子中，具有@Transactional的内部方法来自JpaRepository#save(这是Spring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，您必须在捕获异常后从 BookingResource#createReservtion() 重新抛出异常。还需要确保 createReservtion() 的 @Transactional 中的 noRollbackFor 未设置为与重新抛出的异常相同的任何类型为了表明您想要回滚而不是提交外部方法，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);
    }
}
