@Version 注释无法正常工作

Question

我在 Spring Boot 项目中使用 Java Persistence 版本控制来处理乐观并发控制。

我有 3 个模型：过程、惊人和合同。

过程

@Entity
@Table(name = "processes")
class Process(

...
...
  @Version
  private var version: Int = 0

)

惊人的

@Entity
@Table(name = "amazing")
class Amazing(

        @JsonIgnore
        @ManyToOne
        @JoinColumn(name = "process_id")
        var process: Process

...
...
)

合同

@Entity
@Table(name = "Contracts")
class Contract(

        @JsonIgnore
        @ManyToOne
        @JoinColumn(name = "process_id")
        var process: Process

...
...
)

现在我想从数据库中检索数据。 首先，我调用过程，然后调用惊人和合同的列表。 问题是当我调用第二个列表时，进程的版本会增加！

val process = processRepo.findById(processId) //version is 20
val contracts = contractRepo.findAll() //version is 20
val amazing = amazingRepo.findAll() //version is 21

合约回购

interface ContractRepo : JpaRepository<Contract, Long>

惊人的回购

interface AmazingRepo : JpaRepository<Amazing, Long>

我找不到为什么在没有保存过程的情况下在第二次调用中增加版本的问题？

注意：
我启用 SQL 日志。 所有记录的都是选择。

Answer 1

如果所述实体在一级缓存中，则不需要显式保存实体。

我怀疑您更改了Process某些属性，当您调用amazingRepo.findAll()它会导致Amazing及其依赖的所有实体（包括Process ）刷新。

Answer 2

作为建议，请查看此链接https://www.baeldung.com/jpa-optimistic-locking 。 不同类型的LockModeType有一点，并非所有类型LockModeType在更新时增加版本：

OPTIMISTIC - 它为包含版本属性的所有实体获取乐观读锁

OPTIMISTIC_FORCE_INCREMENT - 它获得与 OPTIMISTIC 相同的乐观锁，并额外增加版本属性值

阅读——它是乐观的同义词

WRITE – 它是 OPTIMISTIC_FORCE_INCREMENT 的同义词

如何配置的一个小例子：

@Lock(LockModeType.OPTIMISTIC)
public Optional<YourEntity> findById(Long id);
