Infinite Recursion with Jackson JSON and Hibernate JPA issue

Question

When trying to convert a JPA object that has a bi-directional association into JSON, I keep getting

org.codehaus.jackson.map.JsonMappingException: Infinite          


        

Answer 1

The new annotation @JsonIgnoreProperties resolves many of the issues with the other options.

@Entity

public class Material{
   ...    
   @JsonIgnoreProperties("costMaterials")
   private List costSuppliers = new ArrayList<>();
   ...
}

@Entity
public class Supplier{
   ...
   @JsonIgnoreProperties("costSuppliers")
   private List costMaterials = new ArrayList<>();
   ....
}

Check it out here. It works just like in the documentation:
