How to reference an entity with inheritance in Spring Data REST when POSTing new entity?

Question

I have entities with joined inheritance:

Supporter

@Entity
@Inheritance(strategy=InheritanceType.JOINED)
@Js         


        

Answer 1

Just another workaround using a RelProvider:

1. Do not use @JsonTypeInfo

2. Create a RelProvider for SupporterEntity sub-classes

   @Component
   @Order(Ordered.HIGHEST_PRECEDENCE)
   public class SupporterEntityRelProvider implements RelProvider {
   
     @Override
     public String getCollectionResourceRelFor(final Class type) {
       return "supporters";
     }
   
     @Override
     public String getItemResourceRelFor(final Class type) {
       return "supporter";
     }
   
     @Override
     public boolean supports(final Class delimiter) {
       return org.apache.commons.lang3.ClassUtils.isAssignable(delimiter, SupporterEntity.class);
     }
   }
