spring - 防止 hibernate StaleObjectStateException 发生

Question

我有一个 Spring Controller 方法的问题。它实际上对同一实体进行了两次更新，这会导致 StaleObjectStateException 。

问题是，当我检索 Member 实例时，我认为它会以某种方式导致 Advertisement 实例的更新(参见 //UPDATE ONE )(这实际上并不需要)，当我更新 Advertisement 实例(参见 //UPDATE TWO )时，它会抛出一个 StaleObjectStateException 。

我的问题是如何防止在我的情况下发生此异常(请记住我使用的是 Spring Data JPA)？

这是 Member 实体类:

@Entity
public class Member {
...
@OneToMany(fetch = FetchType.LAZY, mappedBy = "member")
private List<Advertisement> advertisements;
...

在 Advertisement 实体类中:

@NotNull
@ManyToOne(fetch = FetchType.LAZY)
private Member member;

这是 Controller 方法:

@RequestMapping(value = "/family/advertisement/edit", method = RequestMethod.POST, produces = "text/html")
    public String editFamilyAdvertisement(@ModelAttribute @Validated(value = Validation.AdvertisementCreation.class) FamilyAdvertisementInfo familyAdvertisementInfo,           BindingResult bindingResult, Model model) {
        Member member = memberService.retrieveCurrentMember();//UPDATE ONE
        if (!advertisementService.advertisementBelongsToMember(familyAdvertisementInfo.getFamilyAdvertisement(), member)) {
            throw new IllegalStateException("advertisement does not belong to member");
        }
        if (bindingResult.hasErrors()) {
            populateModel(model, familyAdvertisementInfo);
            return "family/advertisement/edit";
        }
        familyAdvertisementInfo.getFamilyAdvertisement().setMember(member);
        advertisementService.editFamilyAdvertisement(familyAdvertisementInfo.getFamilyAdvertisement());//UPDATE TWO
        return "redirect:/family/advertisement/edit/" + familyAdvertisementInfo.getFamilyAdvertisement().getId();
    }

这是堆栈跟踪:

编辑 2 :我必须提到 我使用 Spring Roo + JPA 默认提供的实体版本控制。 我很确定必须考虑到这一点。

编辑 3 :我设置了一个示例应用程序，用于演示 github 上的 here 问题。任何希望帮助我的人都可以按如下方式克隆该应用程序: git clone https://github.com/balteo/sample-app-gab 。

我有一个类似的问题。这是我在运行 mvn test 时遇到的错误:

org.hibernate.StaleObjectStateException:行已被另一个事务更新或删除(或未保存的值映射不正确)

这是因为我错误地将实体的 version 字段初始化为 NULL :

mysql> select * from lap;
+----+-------------+---------------------+------+------------------+---------+---------+
| id | code        | cumulative_distance | name | partial_distance | version | race_id |
+----+-------------+---------------------+------+------------------+---------+---------+
|  1 | AF0CUL00011 |                1000 | LAP1 |             1000 |    NULL |       1 |
|  2 | AQ000000012 |                2000 | LAP2 |             1000 |    NULL |       2 |
|  3 | AR000000013 |                3000 | LAP3 |             1000 |    NULL |       3 |
|  4 | AR0000N0114 |                4000 | LAP4 |             1000 |    NULL |       4 |
+----+-------------+---------------------+------+------------------+---------+---------+
4 rows in set (0.00 sec)

有一次，我用 0 初始化了 version 字段，一切正常:

mysql> select * from lap;
+----+-------------+---------------------+------+------------------+---------+---------+
| id | code        | cumulative_distance | name | partial_distance | version | race_id |
+----+-------------+---------------------+------+------------------+---------+---------+
|  1 | AF0CUL00011 |                1000 | LAP1 |             1000 |       0 |       1 |
|  2 | AQ000000012 |                2000 | LAP2 |             1000 |       0 |       2 |
|  3 | AR000000013 |                3000 | LAP3 |             1000 |       0 |       3 |
|  4 | AR0000N0114 |                4000 | LAP4 |             1000 |       0 |       4 |
