我正在使用以下技术：

这是我的UserDaoImpl.Java：

小编典典

我在您的错误消息“ 严重： 提交异常被回滚异常覆盖
”中发现了一些奇怪的东西。如果查看UserDaoImpl.Java文件中的try块，则具有return语句，该语句在返回之前关闭休眠连接。而且你必须session.close()在finally块声明，没有任何意义，因为连接已经关闭。您介意删除session.close()声明，然后重试。让我知道这是否可以解决您的问题。

第一次使用 springboot+jpa 进行操作数据库，刚启动就爆出来异常:

应该在 yml 配置文件中加上:

spring:
   jpa:
    show-sql: true
    hibernate:
      ddl-auto: create
    database-platform: org.hibernate.dialect.PostgreSQLDialect

Hibernate Envers OneToMany Cascade.ALL org.hibernate.HibernateException：找到多个具有给定标识符的行

好的，问题是当你尝试

Car car = new Car();
car.setBrand("Alfa Romeo");
Set<Car> cars = new HashSet<>();
cars.add(car);

Driver driver = new Driver();
driver.setCars(cars);

em.persist(driver);

单向一对多，hibernate执行3条sql语句：

插入驱动程序 (id) 值 (?)
插入汽车（品牌，id）值（？，？）
更新汽车设置 driver_id=?其中 id=?

切换到双向关系

@Entity
@Audited
public class Car {

    @Id
    @GeneratedValue
    private Long id;

    private String brand;

    @ManyToOne
    private Driver driver;

    // Constructor,getters and setters omitted
}

@Entity
@Audited
public class Driver {

    @Id
    @GeneratedValue
    private Long id;

    @OneToMany(cascade = CascadeType.ALL,mappedBy = "driver")
    @AuditJoinTable(name = "car_aud")
    private Set<Car> cars = new HashSet();

    public void setCars(Set<Car> cars) {
        books.forEach(b -> b.setDriver(this));
        this.cars.addAll(cars);
    }

    // Constructor,getters and setters omitted

}

使 Hibernate 只创建 2 个 SQL 语句：

插入驱动程序 (id) 值 (?)
插入汽车 (driver_id,brand,id) 值 (?,?,?)

结果相同。所以CAR_AUD表中不会有歧义。

可能是使用 getCurrentSession () 出现了问题，问题原因可能是 hibernate.cfg.xml 文件中的

<!-- 在hibernate核心配置文件中配置 -->
        <property name="hibernate.current_session_context_class">thread</property>

没有配置对。修改便是。
