Annotation Type JsonComponent

@Target(TYPE) @Retention(RUNTIME) @Documented @Component public @interface JsonComponent
@Component that provides JsonSerializer, JsonDeserializer or KeyDeserializer implementations to be registered with Jackson when JsonComponentModule is in use. Can be used to annotate implementations directly or a class that contains them as inner-classes. For example: 
 @JsonComponent
 public class CustomerJsonComponent {

     public static class Serializer extends JsonSerializer<Customer> {

         // ...

     }

     public static class Deserializer extends JsonDeserializer<Customer> {

         // ...

     }

 }
