Hide Object reference in JSON serialization by Jackson when using #JsonIdentityInfo - json

Question

I have two entities: Category and Item.
Category Entity:
#JsonInclude(Include.NON_EMPTY)
#JsonIdentityInfo(generator = ObjectIdGenerators.UUIDGenerator.class)
#Entity
public class Category {
#Id
#GeneratedValue
private int id;
private String categoryName;
#OneToMany(mappedBy = "category")
private List<Item> itemList;
//have getters and setters
}
Item Entity:
#JsonIdentityInfo(generator = ObjectIdGenerators.UUIDGenerator.class)
#Entity
public class Item {
#Id
#GeneratedValue
private int id;
private String itemName;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "fk_Category_id")
private Category category;
//have getters and setters
}
After doing a left join query like this:
"SELECT c from Category c Left JOIN FETCH c.itemList il"
I got the result and then I have done hibernate aware JSON serialization to the result.
My HibernateAwareObjectMapper is:
public class HibernateAwareObjectMapper extends ObjectMapper {
public HibernateAwareObjectMapper() {
Hibernate4Module hibernateModule = new Hibernate4Module();
hibernateModule.disable(Hibernate4Module.Feature.FORCE_LAZY_LOADING);
registerModule(hibernateModule);
}
}
And HibernateAwareSerializerFactory is:
public class HibernateAwareSerializerFactory extends BeanSerializerFactory {
protected HibernateAwareSerializerFactory(SerializerFactoryConfig config) {
super(config);
}
}
In my dispatcher servlet I have written:
<mvc:annotation-driven>
<mvc:message-converters>
<bean
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="org.scinv.hibernateAwareMapper.HibernateAwareObjectMapper" />
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
So, I have got a JSON Like this:
{
"ArrayList": [
{
"#id": "971ef69e-1605-46f2-8234-b595e38be11a",
"id": 1,
"categoryName": "fruit",
"itemList": [
{
"#id": "75a3a7e5-ce66-4f6d-a04c-d04145d92b21",
"id": 1,
"itemName": "mango",
"category": "971ef69e-1605-46f2-8234-b595e38be11a"
},
{
"#id": "0aa0fb71-2909-4909-8403-0765829ee8c1",
"id": 2,
"itemName": "apple",
"category": "971ef69e-1605-46f2-8234-b595e38be11a"
},
{
"#id": "02c381cb-33fa-45a6-bff9-ec146357f4bc",
"id": 3,
"itemName": "orange",
"category": "971ef69e-1605-46f2-8234-b595e38be11a"
}
]
},
"971ef69e-1605-46f2-8234-b595e38be11a",
"971ef69e-1605-46f2-8234-b595e38be11a"
]
}
In this JSON,
there is "#id": "971ef69e-1605-46f2-8234-b595e38be11a"
which is Object Id for Category Entity.
And there is "#id": "75a3a7e5-ce66-4f6d-a04c-d04145d92b21"
which is Object Id for Item Entity.
Category has 3 items So Catagory's object Id is also showing 2 more times.
Like this: "971ef69e-1605-46f2-8234-b595e38be11a","971ef69e-1605-46f2-8234-b595e38be11a"
That Generated JSON serialization is as expected.
But I just need to hide that Object reference "#id" in that json. This "#id" is by default created by #JsonIdentityInfo.
So I need configuration for #JsonIdentityInfo to hide Object Id "#id".
I have tried #JsonIgnore but failed.
I have googled 2 days for solution but failed.Can anyone give me a solution or a suggestion?
