@Target(TYPE)

@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> {

         // ...

     }

 }

 

从以下版本开始:

返回:

返回:

the types that should be handled by the component
