【问题描述】：

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 使用以下代码将我的对象保存到数据库：

    public void addPrincipal(Principal u) {

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

}

trns 是我自己写的事务类的对象，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;

从数据库中获取记录不是问题。当我想将新记录保存到数据库时发生唯一的错误

这是完整的堆栈跟踪。对不起，我忘记了：

【问题讨论】：

异常的完整堆栈跟踪提供了非常有用的信息。阅读并发布。
这似乎不是 full 堆栈跟踪
嗯，这就是我从 Tomcat 日志中得到的全部内容。

标签： java hibernate jpa jdbc entitymanager

【解决方案1】：

如果有意缺少@GeneratedValue，则该问题可能是由缺少@GeneratedValue 注释或管理ID 的代码中的错误引起的。

来自 JPA 主键的 ObjectDB 文档：

如果实体的主键字段没有用@GeneratedValue 标记，则不会自动生成主键值，应用程序负责通过初始化主键字段来设置主键。

【讨论】：

但与@GeneratedValue 完全一样
@GeneratedValue 定义的映射是什么？如果@GeneratedValue 没有使用GenerationType，则意味着JPA 提供者（Hibernate）将根据数据库选择生成主键值的策略。对于 PostgreSQL，当我查看将使用序列的文档时会出现。请参阅Hibernate documentation for the mapping of the id。

【解决方案2】：

尝试在堆栈跟踪中运行插入语句

插入主体（地址、权限、名称、电子邮件、传真、krs、legal_form、姓名、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)
检查表中的约束。表 UNIQUE KEY , FOREIGN KEY 约束中可能有更多约束
