Hibernate无法执行JDBC批量更新

我有一个错误：javax.persistence.PersistenceException：

org.hibernate.exception.ConstraintViolationException：无法执行JDBC批量更新

我通过entiyManager将我的对象持久化到数据库，代码如下：

    public void addPrincipal(Principal u) {

        trns.start();
        trns.getManager().persist(u);
        trns.commit();

}

trns是我自己编写的事务类的对象，这里是使用方法的代码：

 public void start() {
    EntityManager manager = managerFactory.createEntityManager();
    manager.getTransaction().begin();
    entityManager.set(manager);
}

public void commit() {
    EntityManager manager = entityManager.get();
    if (manager == null || !manager.getTransaction().isActive()) {
        throw new IllegalStateException("No transaction is in progress");
    }
    manager.getTransaction().commit();
    manager.clear();
}

public EntityManager getManager() {
    EntityManager manager = entityManager.get();
    if (manager == null) {
        start();
        manager = entityManager.get();
    }
    if (!manager.getTransaction().isActive()) {
        manager.getTransaction().begin();
    }
    return entityManager.get();
}

Principal映射类如下所示：

@Entity
@Table(name = "principal")
public class Principal implements Serializable {

@Id

@Column(name = "id_principal")
private Long id_principal;

@Column(name = "name")
private String name;

@Column(name = "surname")
private String surname;

@Column(name = "designation")
private String designation;

@Column(name = "address")
private String address;

@Column(name = "telephone")
private String telephone;

@Column(name = "fax")
private String fax;

@Column(name = "email")
private String email;

@Column(name = "legal_form")
private String legal_form;

@Column(name = "krs")
private String krs;

@Column(name = "authority")
private String authority;

@Column(name = "pesel_regon")
private String pesel_regon;

@Column(name = "nip")
private String nip;

@Column(name = "stock")
private float stock;

@OneToOne(mappedBy = "principal", cascade = CascadeType.ALL)
private RepresentationPerson representation_person;

@OneToOne(mappedBy = "principal", cascade = CascadeType.ALL)
private ContactPerson contact_person;

@OneToMany(mappedBy = "principal")
private Set<StudyCommisioned> study_commisioned;

从数据库获取记录不是问题。当我想将新记录保存到数据库时，唯一的错误就出现了

这是完整的堆栈跟踪。对不起，我忘记了：

2 个答案:

答案 0 :(得分：1)

  • 尝试在堆栈跟踪中运行insert语句

    插入主体（地址，权限，指定，电子邮件，传真，krs，legal_form，名称，nip，pesel_regon，股票，姓氏，电话，id_principal）值（'sdasd'，'dfsd'，'asdasd'，' ppp@ppp.com'，'3211'，'12456'，'Osoba fizyczna'，'dasdas'，'4312'，'3212'，11.0，'asdasd'，'1234'，2）

  • 检查表格中的约束。表UNIQUE KEY，FOREIGN KEY约束

    • 中可能存在更多约束

答案 1 :(得分：0)

问题可能是由于缺少@GeneratedValue注释或管理id的代码中的错误，如果没有@GeneratedValue是故意的。

来自JPA主键的ObjectDB文档：

  

如果实体的主键字段未标记@GeneratedValue，则不会生成自动主键值，应用程序负责通过初始化主键字段来设置主键。
