How to dynamically avoid sending response containing all properties from relationship data

Question

I am new to spring boot and rest and hence pardon me if this question is very trivial.

I have a situation where the application allows users to register and place order. On registration of user, the service should be able to send a response with the user information including - User Name, email, contact Number, address etc.

However, while placing orders, I would like the order response object to include within the order details, only the customer (username, email). I do not want to include the address and other information part of the User object.

Currently, what is happening is whenever, I refer to an existing user instance within the Order instance, the Order response has the complete tuple information of the registered user.

In the Order confirmation response, I really do not want the entire User information.

However, if the same Order entity is being referenced for user register, I want the service to include all fields from the Order entity.

I have tried referring to the following links -

Jackson Change JsonIgnore Dynamically How do I exclude fields with Jackson not using annotations?

However, the solutions mentioned here will always ignore the attribute in response irrespective of the scenario in which the entity is being referenced.

For example - Response from Order service is as below.

{
    "id": "ORD-1000",
    "priority": null,
    "status": "Open",
    "customer": {
        "id": "1000",
        "name": "Avion Solutions",
        "email": "support-na@avionsolutions.com",
        "contact": null,
        "customerType": "gold-sx",
        "shipToContactId": null,
        "billToContactId": null
    },
    "urgency": null
}

In the above response tuple, lets say, I just want the order information with basic customer information such as name & email.

And if the customer is registering, then the response should contain all the information as mentioned in the above tuple.

How can i dynamically ignore the attributes in response of the REST service based on the context in which the entity object is being used?

Thanks in advance.

I think you need to use separate DTOs not the for different data transfer cases. Please see [this question](https://stackoverflow.com/q/54764493/6413377) for details. — pirho, Feb 23 '19 at 09:25

Try to use @JsonView annotation. You can define visibility for given property and on REST Controller you can define level you want to show. For more information and examples, please, read below:
