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 。
最佳答案
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 |

我希望它有帮助，
