java - TransientPropertyValueException: object references an unsaved transient instance - 在刷新之前保存瞬态实例：

Question

@Entity
@Table(name="tbl_name")
public class Test extends BaseEntity {

    @OneToOne( fetch = FetchType.LAZY)
    @JoinColumn(name = "ALL_ORG_MST_SECTION_ID",nullable = true)
    private AllOrgMst allOrgMstSection;

    @OneToOne(fetch = FetchType.LAZY )
    @JoinColumn(name = "ALL_ORG_MST_SUB_SECTION_ID",nullable = true)
    private AllOrgMst allOrgMstSubSection;


    
}

这是模型。当我插入此模型时，一个对象为空值，然后显示错误

邮递员对象通行证

{
   "allOrgMstSection": {
        "id": 23
    },
    "allOrgMstSubSection": {
        "id": null
    }
}

  @Autowired
    private TestRepository testRepository;

    @Override
    public Test save2(Test entity) {
        return testRepository.save(entity);
    }

在 baseEntity 中有 Id

只是简单地解决了这个问题

{
   "allOrgMstSection": {
        "id": 23
    },
    "allOrgMstSubSection": null,
}
