Spring启动和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，但似乎没有什么工作正常：

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> {

}

Reservation.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？ 我试图将方法公之于众，改变了交易政策，但没有任何作用。 它有一个解决方法吗？

谢谢！

Answer 1

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下时（例如，两者都是Propagation.REQUIRED ，这是默认设置），就会发生这种情况。 然后，当内部方法抛出异常时，它会将TX标记为必需的回滚。 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，因为内部方法表示它想要回滚但外部方法表示它想要提交相互矛盾的内容。

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）。 如果异常发生并且您捕获外部方法中的所有异常（即BookingResource#createReservtion() ），则会发生此异常。

解

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noRollbackFor的@Transactional没有设置为与rethrown异常相同的任何类型，以便表示你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);
    }
}
