Json Infinite Recursion is one of the most common problems when we serialize Java objects which having Bidirectional-Relationships. So in the tutorial JavaSampleApproach will show you how to smoothly handle the problems with Jackson annotations: @JsonIgnore, @JsonView, {@JsonManagedReference, @JsonBackReference} and @JsonIdentityInfo.

I. Infinite Recursion problem
We create 2 model classes: Company & Product have one-to-many relationship:
– Company:
public class Company {
private int id;
private String name;
private List products;
public Company(){
}
...
– Product
public class Product {
private int id;
private String name;
private Company company;
public Product(){
}
Serialize Java Objects with segment code:
(new ObjectMapper()).writeValueAsString(apple);

Why? -> Beacause of the Bidirectional-Relationships between Company objects and Product objects.
II. Solution
Initial an apple Company & 2 Product {iphone7, iPadPro} with segment code:
Product iphone7 = new Product(1, "Iphone 7");
Product iPadPro = new Product(2, "IPadPro");
List appleProducts = new ArrayList(Arrays.asList(iphone7, iPadPro));
Company apple = new Company(1, "Apple", appleProducts);
iphone7.setCompany(apple);
iPadPro.setCompany(apple);
1. Solution 1 – Exclude one side of the relationship by @JsonIgnore or @JsonView
1.1 Use @JsonIgnore
Modify Product with @JsonIgnore
public class Product {
private int id;
private String name;
@JsonIgnore
private Company company;
– Serialize with segment code:
ObjectMapper mapper = new ObjectMapper();
String result = mapper.writeValueAsString(company);
-> Result:
{
"id":1,
"name":"Apple",
"products":[
{
"id":1,
"name":"Iphone 7"
},
{
"id":2,
"name":"IPadPro"
}
]
}
– Deserialize with segment code:
ObjectMapper mapper = new ObjectMapper();
Object object = mapper.readValue(jsonString, valueType);
-> Can not preserve the Bidirectional-Relationships
1.2 Use @JsonView
See How to use @JsonView to serialize/de-serialize and customize JSON format from Java Object.
Modify 2 models Product with @JsonView:
– Company:
public class Company {
@JsonView(View.DetailView.class)
private int id;
@JsonView(View.DetailView.class)
private String name;
@JsonView(View.DetailView.class)
private List products;
public Company(){
}
...
– Product:
public class Product {
@JsonView(View.DetailView.class)
private int id;
@JsonView(View.DetailView.class)
private String name;
private Company company;
public Product(){
}
...
– Serialize with segment code:
ObjectMapper mapper = new ObjectMapper();
mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION);
String result = mapper.writerWithView(serializationView).writeValueAsString(object);
-> Result:
{
"id":1,
"name":"Apple",
"products":[
{
"id":1,
"name":"Iphone 7"
},
{
"id":2,
"name":"IPadPro"
}
]
}– Deserialize with segment code:
ObjectMapper mapper = new ObjectMapper();
Object object = mapper.readerWithView(view).forType(valueType).readValue(jsonString);
-> Can not preserve the Bidirectional-Relationships after deserialization.
2. Solution 2 – Use {@JsonManagedReference, @JsonBackReference} and @JsonIdentityInfo
With the solution we can preserve Bidirectional-Relationships when deserialize Json strings to Java objects
2.1 Use @JsonManagedReference, @JsonBackReference
@JsonManagedReference: a part with the annotation will be serialized normally.
@JsonBackReference: a part with the annotation will be omitted from serialization.
Modify 2 models Product with {@JsonManagedReference, @JsonBackReference}:
– Company:
public class Company {
private int id;
private String name;
@JsonManagedReference
private List products;
public Company(){
}
...
– Product:
public class Product {
private int id;
private String name;
@JsonBackReference
private Company company;
public Product(){
}
...
– Serialize with segment code:
ObjectMapper mapper = new ObjectMapper();
String result = mapper.writeValueAsString(company);
-> Result:
{
"id":1,
"name":"Apple",
"products":[
{
"id":1,
"name":"Iphone 7"
},
{
"id":2,
"name":"IPadPro"
}
]
}
– Deserialize with segment code:
ObjectMapper mapper = new ObjectMapper();
Object object = mapper.readValue(jsonString, valueType);
-> Can preserve the Bidirectional-Relationships after deserialization.
2.2 Use @JsonIdentityInfo
Modify 2 models Product with @JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class,property="@id", scope = Product.class)
– Company:
@JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class,property="@id", scope = Product.class)
public class Company {
private int id;
private String name;
private List products;
public Company(){
}
...
– Product:
@JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class,property="@id", scope = Product.class)
public class Product {
private int id;
private String name;
private Company company;
public Product(){
}
...
– Serialize with segment code:
ObjectMapper mapper = new ObjectMapper();
String result = mapper.writeValueAsString(company);
-> Result:
Serialize Process - JsonString:{
"@id":1,
"id":1,
"name":"Apple",
"products":[
{
"@id":1,
"id":1,
"name":"Iphone 7",
"company":1
},
{
"@id":2,
"id":2,
"name":"IPadPro",
"company":1
}
]
}– Deserialize with segment code:
ObjectMapper mapper = new ObjectMapper();
Object object = mapper.readValue(jsonString, valueType);
-> Can preserve the Bidirectional-Relationships!
1. @JsonIgnore, @JsonView can NOT preserve the Bidirectional-Relationships!
2. {@JsonManagedReference, @JsonBackReference} and @JsonIdentityInfo: can preserve the Bidirectional-Relationships!
2. {@JsonManagedReference, @JsonBackReference} and @JsonIdentityInfo: can preserve the Bidirectional-Relationships!

Good post. I have a question for
@JsonIdentityInfo.I have tried to serialize Product object. its giving like below:
{ "@id":1, "id":1, "name":"Iphone 7", "company":{ "@id":1, "id":1, "name":"Apple", "products":[ 1, { "@id":2, "id":2, "name":"IPadPro", "company":1 }, { "@id":3, "id":2, "name":"IPadPro", "company":1 } ] } }But I should get like:
{ "@id":1, "id":1, "name":"Iphone 7", "company":{ "@id":1, "id":1, "name":"Apple", "products":[ { "@id":1, "id":1, "name":"Iphone 7", "company":1 }, { "@id":2, "id":2, "name":"IPadPro", "company":1 }, { "@id":3, "id":2, "name":"IPadPro", "company":1 } ] } }How to achieve that ?
Hello Thrinath,
serialize Object To String with the info:
{ "@id":1, "id":1, "name":"Iphone 7", "company":{ "@id":1, "id":1, "name":"Apple", "products":[ 1, { "@id":2, "id":2, "name":"IPadPro", "company":1 }, { "@id":3, "id":2, "name":"IPadPro", "company":1 } ] } }That’s enough info and not redundancy for deserialize String To Object.
So Why you want to work-arround with your expected which makes lots of redundancy data and inconsitency?
{ "@id":1, "id":1, "name":"Iphone 7", "company":{ "@id":1, "id":1, "name":"Apple", "products":[ { "@id":1, "id":1, "name":"Iphone 7", "company":1 }, { "@id":2, "id":2, "name":"IPadPro", "company":1 }, { "@id":3, "id":2, "name":"IPadPro", "company":1 } ] } }Regards,
JSA
Wonderful solution. @JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class,property=”@id”, scope = Product.class)
Gracias!
Thank you very much man !
Great post !
I have a doubt:
Why when I search Product by ID, the field of Company comes Null??
Hi Author,
Thanks for the nice tutorials and great posts. However I found that @JsonManagedReference, @JsonBackReference does not gives you the data associated with @OneToMany and @ManyToOne scenario, also when using @JsonIgnoreProperties does skip associated entity data. How to solve this?
I see this solution (@JsonIgnore, @JsonView, etc) provided everywhere.
It seems to be an unsatisfactory solution if you actually need the values associated
with the entity. Perhaps I’m not creative enough but in a RESTful (or otherwise)
service I don’t see a way to send everything needed except by making two DB calls.
Can you clarify a way out of doing that?
Thanks.
Muchas gracias. ?Como puedo iniciar sesion?
