Examples with UriConversion io.neonbee.endpoint.odatav4.ODataV4Endpoint.UriConversion used on opensource projects

Example 1 with UriConversion

use of io.neonbee.endpoint.odatav4.ODataV4Endpoint.UriConversion in project neonbee by SAP.

the class ODataV4EndpointTest method provideWorkingDirectoryBuilder.

@Override
protected WorkingDirectoryBuilder provideWorkingDirectoryBuilder(TestInfo testInfo, VertxTestContext testContext) {
    return super.provideWorkingDirectoryBuilder(testInfo, testContext).setCustomTask(root -> {
        // the server verticle should either use strict, cds or loose URI mapping
        String testMethodName = testInfo.getTestMethod().map(Method::getName).orElse(EMPTY);
        UriConversion uriConversion = STRICT;
        if (testMethodName.contains("LooseUriConversion")) {
            uriConversion = LOOSE;
        } else if (testMethodName.contains("CDSUriConversion")) {
            uriConversion = CDS;
        }
        DeploymentOptions opts = WorkingDirectoryBuilder.readDeploymentOptions(ServerVerticle.class, root);
        EndpointConfig epc = new EndpointConfig().setType(ODataV4Endpoint.class.getName()).setAdditionalConfig(new JsonObject().put(CONFIG_URI_CONVERSION, uriConversion.toString()));
        ServerConfig sc = new ServerConfig(opts.getConfig()).setEndpointConfigs(List.of(epc));
        opts.setConfig(sc.toJson());
        WorkingDirectoryBuilder.writeDeploymentOptions(ServerVerticle.class, opts, root);
    });
}

Example 2 with UriConversion

use of io.neonbee.endpoint.odatav4.ODataV4Endpoint.UriConversion in project neonbee by SAP.

the class ODataV4Endpoint method createEndpointRouter.

@Override
public Future<Router> createEndpointRouter(Vertx vertx, String basePath, JsonObject config) {
    Router router = Router.router(vertx);
    // true if the router was initialized already
    AtomicBoolean initialized = new AtomicBoolean();
    AtomicReference<Map<String, EntityModel>> models = new AtomicReference<>();
    // the URI convention used to expose the given service in the endpoint.
    UriConversion uriConversion = UriConversion.byName(config.getString("uriConversion", STRICT.name()));
    // a block / allow list of all entities that should be exposed via this endpoint. the entity name is always
    // matched against the full qualified name of the entity in question (URI conversion is applied by NeonBee).
    RegexBlockList exposedEntities = RegexBlockList.fromJson(config.getValue("exposedEntities"));
    // Register the event bus consumer first, otherwise it could happen that during initialization we are missing an
    // update to the data model, a refresh of the router will only be triggered in case it is already initialized.
    // This is a NON-local consumer, this means the reload could be triggered from anywhere, however currently the
    // reload is only triggered in case the EntityModelManager reloads the models locally (and triggers a local
    // publish of the message, thus only triggering the routers to be reloaded on the local instance).
    vertx.eventBus().consumer(EVENT_BUS_MODELS_LOADED_ADDRESS, message -> {
        // do not refresh the router if it wasn't even initialized
        if (initialized.get()) {
            refreshRouter(vertx, router, basePath, uriConversion, exposedEntities, models);
        }
    });
    // This router is initialized lazy, this means that all required routes will be populated on first request to
    // said router, not before. This comes with three major advantages: a) it makes the initialization code more
    // easy, as in case we'd first register to the event handler, we'd always have to check if the model is loaded
    // already and potentially have to deal with a race condition b) no model is loaded / routes are initialized if
    // when NeonBee is started and / or in case the endpoint is not used.
    Route initialRoute = router.route();
    initialRoute.handler(routingContext -> new SharedDataAccessor(vertx, ODataV4Endpoint.class).getLocalLock(asyncLock -> (!initialized.getAndSet(true) ? refreshRouter(vertx, router, basePath, uriConversion, exposedEntities, models) : succeededFuture()).onComplete(handler -> {
        // wait for the refresh to finish (the result doesn't matter), remove the initial route, as
        // this will redirect all requests to the registered service endpoint handlers (if non have
        // been registered, e.g. due to a failure in model loading, it'll result in an 404). Could
        // have been removed already by refreshRouter, we don't care!
        initialRoute.remove();
        if (asyncLock.succeeded()) {
            // releasing the lock will cause other requests unblock and not call the initial route
            asyncLock.result().release();
        }
        // let the router again handle the context again, now with either all service endpoints
        // registered, or none in case there have been a failure while loading the models.
        // NOTE: Re-route is the only elegant way I found to restart the current router to take
        // the new routes! Might consider checking again with the Vert.x 4.0 release.
        routingContext.reroute(routingContext.request().uri());
    })));
    return succeededFuture(router);
