Бесконечная рекурсия Hibernate и двунаправленные отношения ⇐ JAVA

[Гость]

I have two entities. I want a bidirectional relationship between projects and tasks.

• A project has one or more tasks
• A task is associated to only one project

There are my entities:

ProjectEntity.java

Код: Выделить всё

@Entity @Table(name = "projects") public class ProjectEntity {     @Id     @GeneratedValue     @Column(name = "pr_id")     private long id;     @Column(name = "pr_name", nullable = false)     private String name;     @OneToMany(cascade=CascadeType.ALL, mappedBy="project",orphanRemoval=true)     @JsonBackReference     private Set tasks = new HashSet();    // Getters, constructors, setters 

TaskEntity.java

Код: Выделить всё

@Entity @Table(name = "tasks") public class TaskEntity {     @Id     @GeneratedValue     @Column(name = "ta_id")     private long id;     @Column(name = "ta_name")     private String name;     @ManyToOne     @JoinColumn(name="pr_id")     @JsonManagedReference     private ProjectEntity project;     // Getters, constructors, setters 

I would like to have the list of tasks in each

ProjectEntity

, and in each

Код: Выделить всё

TaskEntity

the project associated.

Here, I'm using

Код: Выделить всё

@JsonManagedReference

and

Код: Выделить всё

@JsonBackReference

to stop the infinite recursion it generated, but in my

Код: Выделить всё

ProjectEntity

, I don't have the tasks list (because of the

Код: Выделить всё

@JsonBackReference

) ...

Could you help me to get back tasks list in

Код: Выделить всё

ProjectEntity

? I heard about

Код: Выделить всё

@JsonIdentifyInfo

, but I have not managed to do with.

Hope I'm understandable
