Annotation Interface APIResponse

@Target({METHOD,TYPE}) @Retention(RUNTIME) @Inherited @Repeatable(APIResponses.class) public @interface APIResponse
The APIResponse annotation corresponds to the OpenAPI Response model object which describes a single response from an API Operation, including design-time, static links to operations based on the response.

When this annotation is applied to a JAX-RS method the response is added to the responses defined in the corresponding OpenAPI operation. If the operation already has a response with the specified responseCode the annotation on the method is ignored. 

 @APIResponse(responseCode = "200", description = "Calculate load size", content = {
         @Content(mediaType = "application/json", Schema = @Schema(type = "integer"))})
 @GET
 public getLuggageWeight(Flight id) {
     return getBagWeight(id) + getCargoWeight(id);
 }

When this annotation is applied to a JAX-RS resource class, the response is added to the responses defined in all OpenAPI operations which correspond to a method on that class. If an operation already has a response with the specified responseCode the response is not added to that operation.

When this annotation is applied to an ExceptionMapper class or toResponse method, it allows developers to describe the API response that will be added to a generated OpenAPI operation based on a JAX-RS method that declares an Exception of the type handled by the ExceptionMapper. 

 @Provider
 public class NotFoundExceptionMapper implements ExceptionMapper<NotFoundException> {
     @Override
     @APIResponse(responseCode = "404", description = "Not Found")
     public Response toResponse(NotFoundException t) {
         return Response.status(404)
                 .type(MediaType.TEXT_PLAIN)
                 .entity("Not found")
                 .build();
     }
 }

  • Element Details

    • description

      String description
      A short description of the response. It is a REQUIRED property unless this is only a reference to a response instance.
      Returns:
      description of the response.
      Default:
      ""

    • responseCode

      String responseCode
      The HTTP response code, or 'default', for the supplied response. May only have 1 default entry.
      Returns:
      HTTP response code for this response instance or default
      Default:
      "default"

    • headers

      Header[] headers
      An array of response headers. Allows additional information to be included with response.

      RFC7230 states header names are case insensitive. If a response header is defined with the name "Content-Type", it SHALL be ignored.

      Returns:
      array of headers for this response instance
      Default:
      {}

    • links

      Link[] links
      An array of operation links that can be followed from the response.
      Returns:
      array of operation links for this response instance
      Default:
      {}

    • content

      Content[] content
      An array containing descriptions of potential response payloads for different media types.
      Returns:
      content of this response instance
      Default:
      {}

    • name

      String name
      The unique name to identify this response. Only REQUIRED when the response is defined within Components. The name will be used as the key to add this response to the 'responses' map for reuse.
      Returns:
      this response's name
      Default:
      ""

    • ref

      String ref
      Reference value to a Response object.

      This property provides a reference to an object defined elsewhere. This property and all other properties are mutually exclusive. If other properties are defined in addition to the ref property then the result is undefined.

      Returns:
      reference to a response
      Default:
      ""

    • extensions

      Extension[] extensions
      List of extensions to be added to the APIResponse model corresponding to the containing annotation.
      Returns:
      array of extensions
      Since:
      3.1
      Default:
      {}
