Hibernate：坚持@OneToMany 无一例外地卡住（其中子实体插入未在 showsql 中打印）

Question

主要实体：

 CustomerAgreement {

     @OneToMany(mappedBy = "customerAgreement", orphanRemoval = true, fetch = FetchType.LAZY, cascade = {CascadeType.ALL})
     private List<CustomerAgreementPeriod> agreementPeriods;
 }

引用 ManyToOne 的实体：

public class CustomerAgreementPeriod  implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @SequenceGenerator(name = "CustomerAgreementPeriodSeq", sequenceName = "CUST_AGT_PERIOD_SEQ")
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "CustomerAgreementPeriodSeq")
    @Column(name = "ID")
    private Long id;

    @ManyToOne
    @JoinColumn(name = "CUSTID")
    private CustomerAgreement customerAgreement;
   .
  .
 }

主要代码：

CustomerAgreement cAgreement = new CustomerAgreement();
        cAgreement.setId(32121212l);
        cAgreement.setName("Kiki");;
        cAgreement.setCustomerId("140");

        List<CustomerAgreementPeriod> cap = new ArrayList<>();
        CustomerAgreementPeriod capy = new CustomerAgreementPeriod();
        capy.setPid("1");
        capy.setValidFrom(new Date());
        capy.setValidTo(new Date());
        capy.setCustomerAgreement(cAgreement);

        CustomerAgreementPeriod capy2 = new CustomerAgreementPeriod();
        capy2.setPid("2");
        capy2.setValidFrom(new Date());
        capy2.setValidTo(new Date());
        capy2.setCustomerAgreement(cAgreement);

        cap.add(capy);
        cap.add(capy2);
        cAgreement.setAgreementPeriods(cap);
        em.getTransaction().begin();
        em.persist(cAgreement);
        em.getTransaction().commit();

错误：

没有显示错误，但只有一个向main的插入查询，如下所示：

Hibernate: 
    select
        CUST_AGT_PERIOD_SEQ.nextval 
    from
        dual
Hibernate: 
    select
        CUST_AGT_PERIOD_SEQ.nextval 
    from
        dual
Hibernate: 
    insert 
    into
        CIM_SNOW_CUST_AGREEMENT_TAB
    values

似乎线程卡在某处可能是无限循环或其他问题。

任何人都可以建议为什么会发生这种情况以及如何解决这个问题吗？

Answer 1

这个问题是我这边的。

但这很奇怪，Hibernate 没有抛出任何异常并保持运行。

问题：根据上述实体，table 中不存在字段 ID 和 CUSTID。

我认为我们应该始终在 persistance.xml 中添加验证属性以在部署时进行验证
