Holon platform JAX-RS module

Latest release: 5.5.0

This is the JAX-RS module of the Holon Platform, which provides support, components and configuration helpers concerning the JAX-RS - Java API for RESTful Web Service standard.

The module main features are:

  • A JAX-RS implementation of the core platform RestClient API, a complete and easy to use RESTful web services Java client, including an asynchronous and a reactive (using Project Reactor) version.
  • A set of standard JAX-RS components to implement server-side API authentication and authorization using platform core APIs and services, such as Realm and AuthContext, in addition to standard javax.annotation.security standard annotations.
  • A complete integration with Swagger OpenAPI Specification, both for version 2 and 3, including support for the PropertyBox core platform data container interface (to be exposed as a Swagger Model definition) and for Swagger API listing endpoints (both in JSON and YAML formats) configuration.
  • Spring Boot auto-configuration classes to automatically register suitable Spring beans (for example beans annotated with @Path or @Provider) as resources in a JAX-RS compliant server.
  • Spring Boot auto-configuration artifact to automatically enable and configure a Resteasy server with Spring integration.
  • A set of Spring Boot starters to setup JAX-RS compliant clients and servers:

See the module documentation for details.

Just like any other platform module, this artifact is part of the Holon Platform ecosystem, but can be also used as a stand-alone library.

See Getting started and the platform documentation for further details.

At-a-glance overview

JAX-RS Property model support:

// Property model
public interface Subject {
		
	static final NumericProperty<Long> ID = NumericProperty.longType("id");
	static final StringProperty NAME = StringProperty.create("name");
	static final StringProperty SURNAME = StringProperty.create("surname");

	static final PropertySet<?> SUBJECT = PropertySet.of(ID, NAME, SURNAME);
		
	static final DataTarget<?> TARGET = DataTarget.named("subjects");

}

// JAX-RS endpoint
@Path("/subjects")
public class SubjectEndpoint {

	@Inject
	private Datastore datastore;
		
	@GET
	@Path("/")
	@Produces(MediaType.APPLICATION_JSON)
	public List<PropertyBox> getSubjects() {
		return datastore.query().target(TARGET).list(SUBJECT);
	}

	@GET
	@Path("/{id}")
	@Produces(MediaType.APPLICATION_JSON)
	public Response getSubject(@PathParam("id") Long id) {
		return datastore.query().target(TARGET).filter(ID.eq(id)).findOne(SUBJECT)
		.map(p -> Response.ok(p).build())
		.orElse(Response.status(Status.NOT_FOUND).build());
	}

	@POST
	@Path("/")
	@Consumes(MediaType.APPLICATION_JSON)
	public Response addSubject(@PropertySetRef(Subject.class) PropertyBox subject) {
		datastore.save(TARGET, subject, DefaultWriteOption.BRING_BACK_GENERATED_IDS);
		return Response.created(URI.create("/api/subjects/" + subject.getValue(ID))).build();
	}

}

JAX-RS API documentation using Swagger:

holon:
  swagger:
    path: 'docs'
    title: 'API title'
    version: 'v1'
@Path("example")
@Component
public class Endpoint {
	/* operations omitted */
}

JAX-RS authentication using JWT and Spring Boot:

holon:
  jwt:
    signature-algorithm: HS256
    sharedkey-base64: eWGZLlCrUjtBZwxgzcLPnA
    expire-hours: 1
    issuer: example-issuer
// Ream with JWT authentication support
@Bean
public Realm realm(JwtConfiguration jwtConfiguration) {
  return Realm.builder().resolver(AuthenticationToken.httpBearerResolver())
  	.authenticator(JwtAuthenticator.builder().configuration(jwtConfiguration).build())
  	.withDefaultAuthorizer().build();
}

// Protected JAX-RS endpoint
@Authenticate
@Path("/api/protected")
public class ApiEndpoint {

	@RolesAllowed("ROLE1")
	@GET
	@Path("/operation")
	public Response userOperation(@Context SecurityContext securityContext) {

		// principal name
		String principalName = securityContext.getUserPrincipal().getName();
		// authentication from JSON Web Token
		Authentication auth = (Authentication) securityContext.getUserPrincipal();

		return Response.ok(principalName).build();
	}

}

JAX-RS RestClient:

RestClient client = RestClient.forTarget("https://host/api");
		
Optional<TestData> data = client.request().path("data/{id}").resolve("id", 1)
	.accept(MediaType.APPLICATION_JSON).getForEntity(TestData.class);

Optional<PropertyBox> value = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).getForEntity(PropertyBox.class);

ResponseEntity<PropertyBox> response = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).get(PropertyBox.class);

List<PropertyBox> values = client.request().path("get_property_boxes_json")
	.propertySet(SUBJECT).getAsList(PropertyBox.class);

ResponseEntity<Void> postResponse = client.request().path("postbox")
	.post(RequestEntity.json(PropertyBox.builder(SUBJECT).set(ID, 1).set(NAME, "Test").build()));

JAX-RS Asynchronous RestClient (since version 5.2):

AsyncRestClient client = AsyncRestClient.forTarget("https://host/api");
		
CompletionStage<Optional<TestData>> data = client.request().path("data/{id}").resolve("id", 1)
	.accept(MediaType.APPLICATION_JSON).getForEntity(TestData.class);

CompletionStage<Optional<PropertyBox>> value = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).getForEntity(PropertyBox.class);

CompletionStage<ResponseEntity<PropertyBox>> response = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).get(PropertyBox.class);

CompletionStage<List<PropertyBox>> values = client.request().path("get_property_boxes_json")
	.propertySet(SUBJECT).getAsList(PropertyBox.class);

CompletionStage<ResponseEntity<Void>> postResponse = client.request().path("postbox")
	.post(RequestEntity.json(PropertyBox.builder(SUBJECT).set(ID, 1).set(NAME, "Test").build()));

JAX-RS Reactive RestClient (since version 5.2):

ReactiveRestClient client = ReactiveRestClient.forTarget("https://host/api");
		
Mono<TestData> data = client.request().path("data/{id}").resolve("id", 1)
	.accept(MediaType.APPLICATION_JSON).getForEntity(TestData.class);

Mono<PropertyBox> value = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).getForEntity(PropertyBox.class);

Mono<ReactiveResponseEntity<PropertyBox>> response = client.request().path("get_property_box_json")
	.propertySet(SUBJECT).get(PropertyBox.class);

Flux<PropertyBox> values = client.request().path("get_property_boxes_json")
	.propertySet(SUBJECT).getAsList(PropertyBox.class);

Mono<ReactiveResponseEntity<Void>> postResponse = client.request().path("postbox")
	.post(RequestEntity.json(PropertyBox.builder(SUBJECT).set(ID, 1).set(NAME, "Test").build()));
