问题描述
我在Jackson 1.6.3和Hibernate方面遇到了问题。我在这里找到了这个主题:但它没有解决问题。
我有一个Node对象来来往往的关系。即使使用@JsonManagedReference注解,在应用程序服务器的控制台上,我也可以看到引发的异常(无限递归)。
有没有其他选择?(b
$ b $ @ b
$ @
$公共类Node实现Serializable {
@Id
私人字符串ID;
@Column(name =x_pos)
private double x;
@Column(name =y_pos)
private double y;
$ b @OneToMany
@JoinColumn(name =source)
@JsonManagedReference(outgoingRelations)
private Set< Relation> outgoingRelations;
@OneToMany
@JoinColumn(name =target)
@JsonManagedReference(incomingRelations)
private Set< Relation> incomingRelations;
$ b @Entity
@Table(name =relations)
公共类关系实现Serializable {
@ Id
私人长ID;
@ManyToOne
@JoinColumn(name =source)
@JsonBackReference(outgoingRelations)
私有节点源;
@ManyToOne
@JoinColumn(name =target)
@JsonBackReference(incomingRelations)
私有节点目标;
问候
I'm having problems with Jackson 1.6.3 and Hibernate. I found this thread here : Infinite Recursion with Jackson JSON and Hibernate JPA issue
But it did not solve the problem.
I have a Node object that has incoming and outgoing relations. Even with the @JsonManagedReference annotations, on the console of the app server I can see the exceptions being thrown (infinite recursion).
Is there any alternative to that?
@Entity
@Table(name="nodes")
public class Node implements Serializable {
@Id
private String id;
@Column(name="x_pos")
private double x;
@Column(name="y_pos")
private double y;
@OneToMany
@JoinColumn(name="source")
@JsonManagedReference("outgoingRelations")
private Set<Relation> outgoingRelations;
@OneToMany
@JoinColumn(name="target")
@JsonManagedReference("incomingRelations")
private Set<Relation> incomingRelations;
@Entity
@Table(name="relations")
public class Relation implements Serializable {
@Id
private Long id;
@ManyToOne
@JoinColumn(name="source")
@JsonBackReference("outgoingRelations")
private Node source;
@ManyToOne
@JoinColumn(name="target")
@JsonBackReference("incomingRelations")
private Node target;
