Spring Data REST - How to sort an entity by JSON ignored field?

Question

I am using Spring Data REST and I have the following entity in my project.

@Data
@Entity
public class Loan{

    @Id
    @GeneratedValue
    private Long id;

    @JsonIgnore
    private Long createdDate;

    private Long amount;

    private Long repaymentStartDate;

}

Now I want to sort the loans by the createdDate which will be automatically filled and JSONIgnored to prevent it from being updated. But I am unable to sort the loans by the createdDate when I call the endpoint loans?sort=createdDate .

How do I fix this?

Here is my repository:

public interface LoanRepository extends PagingAndSortingRepository<Loan, Long>{

}

Answer 1

To workaround try to replace @JsonIgnore to @JsonProperty(access = READ_ONLY) . It prevents createdDate from changing but remains it in the json body.

UPDATED

For Spring Boot 1.5.10+ instead of @JsonProperty(access = READ_ONLY) you can use @JsonIgnoreProperties("createdDate") on top of the entity.
