Question

我遇到了Spring控制器方法的问题。它实际上对同一个实体进行了两次更新，导致 StaleObjectStateException 。

问题在于，当我检索成员实例时，我认为它会以某种方式导致广告实例的更新（请参阅//UPDATE ONE）（实际上并不需要）以及更新广告实例时（请参阅{ {1}}），然后抛出 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Spring Data JPA）？

这是//UPDATE TWO实体类：

Member

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

Advertisement

这是控制器方法：

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

这是stacktrace：

@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();
    }

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

编辑3 ：我已经设置了一个示例应用程序，用于演示github上的问题here。任何希望帮助我的人都可以按如下方式克隆应用：@RooJavaBean @RooToString @RooEquals @RooJpaEntity @Entity @DynamicUpdate public class FamilyAdvertisement extends Advertisement { @NotNull(groups = Validation.AdvertisementCreation.class) @ElementCollection private Set<Need> needs; @ElementCollection private Set<ChildminderStatus> childminderStatuses; @AssertTrue @Override public boolean isChildcareTypesValid() { return true; } @AssertTrue public boolean isNeedsValid() { if (needs.isEmpty()) { return false; } if (needs.contains(Need.CHILDMINDER_TO_FAMILY)) { return false; } return true; } }。

我有类似的问题。这是我在运行mvn test时遇到的错误：

org.hibernate.StaleObjectStateException：行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 |
+----+-------------+---------------------+------+------------------+---------+---------+
4 rows in set (0.00 sec)

我希望它有所帮助，奥古斯丁

“org.hibernate.StaleObjectStateException：行被另一个事务更新或删除（或未保存的值映射不正确）：[com.bignibou.domain.FamilyAdvertisement＃1]”提出了两个原因 - 一些意外更新（鉴于您正在选择数据，这会很奇怪）或JPA映射中的错误。

请添加SQL查询日志记录并发布由JPA生成的SQL查询。还请发布FamilyAdvertisment课程。查询日志记录取决于JPA提供程序（请参阅此提示：How to view the SQL queries issued by JPA?）
