Spring数据CURD存储库在保存调用时因多个对象失败

Question

我已经定义了实体类 ExportRecordStatus，它具有像其中一个属性一样的 Integer Id。

ExportRecordStatus 使用所有值定义，保存时会为单个实体保存，但对于多个实体会失败。

exportRecordStatusList 有以下条目：

[ExportRecordStatus 
[Id=null, runId=55801, mdmItemId=1111, endPointItemId=null, statusTime=xxxxx, endPointName=xxx, status=ERROR, detailStatus=xxxx, endPointResponseCode=null],

ExportRecordStatus
[Id=null, runId=55801, mdmItemId=2222, endPointItemId=null, statusTime=xxxx, endPointName=xxx, status=ERROR, detailStatus=xxx, endPointResponseCode=null]
]
Id being primary key.

org.springframework.dao.DataIntegrityViolationException: 不能 执行语句； SQL [不适用]；约束 [null];嵌套异常是 org.hibernate.exception.ConstraintViolationException：不能 执行语句

实体被定义为带有 Id 属性的注释如下：

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "qconn_ers_id")
@SequenceGenerator(name="qconn_ers_id", sequenceName = "qconn_ers_id", allocationSize=1)
@Column(name = "ERS_ID", updatable = false, nullable = false)
pdefined Integer Id;

我已将存储库类定义如下

public interface ExportRecordStatusCRUDRepository extends CrudRepository<ExportRecordStatus, Integer> {}

在调用单个对象时，它适用于单个对象。

exportRecordStatusCRUDRepository.save(exportRecordStatus);

但如果有多个对象，它会失败并引发异常。

保存应该成功，并且每个 ExportRecordStatus 对象的 Id 应该具有唯一值。

全栈复制如下-

在这方面需要帮助。提前谢谢你。

我可以解决这个问题，我绑定实体类属性和数据库的方式存在问题，有 2 个属性是用唯一约束定义的，并且不知何故我的应用程序正在为 2 条记录推送相同的时间戳，但它失败了。 感谢大家的快速投入。
