JPA 使用双向 @OneToMany 抛出 java.lang.StackOverflowError
JPA throws java.lang.StackOverflowError with bidirectional @OneToMany
我有两个实体 class，如下所示。 Parachute 是 parent object，它有多个 Component object。我需要在这里实现双向@OneToMany。
Parent Parachute.java class.
@Entity
@Table(name = "parachute")
@EntityListeners(AuditingEntityListener.class)
public class Parachute {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@OneToMany(mappedBy = "parachute",cascade = CascadeType.ALL, fetch=FetchType.EAGER)
private List<Component> components = new ArrayList<>();
public void addComponent(Component component) {
components.add(component);
component.setParachute(this);
}
}
Child Component.java class
@Entity
@Table(name = "component")
@EntityListeners(AuditingEntityListener.class)
public class Component {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@ManyToOne
@JoinColumn(name = "parachute_id")
private Parachute parachute;
}
我尝试如下添加降落伞。
Component component1 = new Component();
component1.setSerialNumber("12121999");
Component component2 = new Component();
component2.setSerialNumber("12121910");
Parachute parachute = new Parachute();
parachute.setName("new Para");
parachute.addComponent(component1);
parachute.addComponent(component2)
parachuteRepository.save(parachute);
这给了我一个java.lang.WhosebugError。我做错了吗还是有其他方法可以做到这一点？

您在生命周期侦听器中访问持久性上下文违反了 JPA 规范。
参见 JPA 规范 4.2 第 3.5.2 节
In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship
state of the entity on which it is invoked.
“便携式应用程序不应该”是规范的说法：不要那样做，任何事情都可能发生。也许世界末日。
解决方法是不要那样做。也许会预加载当前登录的用户并引用它，这样您就可以在您的实体侦听器中访问它并且不设置对用户的引用，而是简单地存储其 ID 或类似内容。
我有两个实体 class，如下所示。 Parachute 是 parent object，它有多个 Component object。我需要在这里实现双向@OneToMany。
Parent Parachute.java class.
@Entity
@Table(name = "parachute")
@EntityListeners(AuditingEntityListener.class)
public class Parachute {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@OneToMany(mappedBy = "parachute",cascade = CascadeType.ALL, fetch=FetchType.EAGER)
private List<Component> components = new ArrayList<>();
public void addComponent(Component component) {
components.add(component);
component.setParachute(this);
}
}
Child Component.java class
@Entity
@Table(name = "component")
@EntityListeners(AuditingEntityListener.class)
public class Component {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@ManyToOne
@JoinColumn(name = "parachute_id")
private Parachute parachute;
}
我尝试如下添加降落伞。
Component component1 = new Component();
component1.setSerialNumber("12121999");
Component component2 = new Component();
component2.setSerialNumber("12121910");
Parachute parachute = new Parachute();
parachute.setName("new Para");
parachute.addComponent(component1);
parachute.addComponent(component2)
parachuteRepository.save(parachute);

您在生命周期侦听器中访问持久性上下文违反了 JPA 规范。
参见 JPA 规范 4.2 第 3.5.2 节
In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked.
“便携式应用程序不应该”是规范的说法：不要那样做，任何事情都可能发生。也许世界末日。
解决方法是不要那样做。也许会预加载当前登录的用户并引用它，这样您就可以在您的实体侦听器中访问它并且不设置对用户的引用，而是简单地存储其 ID 或类似内容。
