JsonBackReference not working as expected - json

Question

I have the next two clases...
Class A
#Entity
#Table(name="ClassA")
public class ClassA
{
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "Id", unique = true, nullable = false)
private Long id;
#Column(name = "Name", nullable = false, length = 50)
private String name;
#JsonManagedReference
#OneToMany(mappedBy="classA")
private List<ClassB> classBList;
}
Class B
#Entity
#Table(name = "ClassB")
public class ClassB
{
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "Id", unique = true, nullable = false)
private Long id;
#Column(name = "Name", nullable = false, length = 50)
private String name;
#JsonBackReference
#ManyToOne
#JoinColumn(name = "ClassAId", nullable = false)
private ClassA classA;
}
When i do a get of all ClassA records from database using REST the result is working like charm:
GET http://localhost:8080/REST/ClassA
[
{
"id": 1,
"name": "VVVV I",
"classB": [
{
"id": 1,
"name": "SSSS I"
},
{
"id": 2,
"name": "QQQQ II",
}
]
},
{
"id": 2,
"name": "RRRR II",
"classB": []
},
{
"id": 3,
"name": "FFFFF III",
"classB": []
},
{
"id": 4,
"name": "QWERR",
"classB": [
{
"id": 3,
"name": "GGGG III",
},
{
"id": 4,
"name": "HHHH IV",
},
{
"id": 5,
"name": "JJJJ V",
}
]
},
{
"id": 5,
"name": "TRRR",
"classB": []
}
]
The problem is when i want to get the list of ClassB, the ClassA is not returning at all...
GET http://localhost:8080/REST/ClassB
[
{
"id": 1,
"name": "SSSS I"
},
{
"id": 2,
"name": "QQQQ II"
},
{
"id": 3,
"name": "GGGG III"
},
{
"id": 4,
"name": "HHHH IV"
},
{
"id": 5,
"name": "JJJJ V"
}
]
I need ClassA (without classB inside of it) be listed when getting list of ClassB
How can i achieve that?
Best regards
