Annotation Type JsonComponent

@Target(value=TYPE)
 @Retention(value=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> {

         // ...

     }

 }
