Examples with Routing io.helidon.webserver.Routing used on opensource projects

Example 6 with Routing

use of io.helidon.webserver.Routing in project metro-jax-ws by eclipse-ee4j.

the class Main method startServer.

static WebServer startServer() {
    setupLogging();
    // By default this will pick up application.yaml from the classpath
    Config config = buildConfig();
    // Get webserver config from the "server" section of application.yaml
    WebServer server = WebServer.builder().config(config.get("server")).routing(buildRouting(config)).build();
    // Try to start the server. If successful, print some info and arrange to
    // print a message at shutdown. If unsuccessful, print the exception.
    server.start().thenAccept(ws -> {
        System.out.println("WEB server is up! http://localhost:" + ws.port());
        ws.whenShutdown().thenRun(() -> System.out.println("WEB server is DOWN. Good bye!"));
    }).exceptionally(t -> {
        System.err.println("Startup failed: " + t.getMessage());
        t.printStackTrace(System.err);
        return null;
    });
    // Server threads are not daemon. No need to block. Just react.
    return server;
}

Example 7 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method main.

/**
 * Start the example. Prints endpoints to standard output.
 *
 * @param args not used
 */
public static void main(String[] args) {
    serverStartTime = System.currentTimeMillis();
    HealthSupport health = HealthSupport.builder().addLiveness(HealthChecks.healthChecks()).addReadiness(() -> HealthCheckResponse.named("exampleHealthCheck").up().withData("time", System.currentTimeMillis()).build()).addStartup(() -> HealthCheckResponse.named("exampleStartCheck").status(isStarted()).withData("time", System.currentTimeMillis()).build()).build();
    Routing routing = Routing.builder().register(health).get("/hello", (req, res) -> res.send("Hello World!")).build();
    WebServer ws = WebServer.create(routing);
    ws.start().thenApply(webServer -> {
        String endpoint = "http://localhost:" + webServer.port();
        System.out.println("Hello World started on " + endpoint + "/hello");
        System.out.println("Health checks available on " + endpoint + "/health");
        return null;
    });
}

Example 8 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method startServer.

/**
 * Start the server.
 * @return the created {@link WebServer} instance
 */
static Single<WebServer> startServer() {
    // load logging configuration
    LogConfig.configureRuntime();
    // By default this will pick up application.yaml from the classpath
    Config config = Config.create();
    WebServer server = WebServer.builder().routing(createRouting(config)).config(config.get("server")).addMediaSupport(JsonpSupport.create()).build();
    Single<WebServer> webserver = server.start();
    // Try to start the server. If successful, print some info and arrange to
    // print a message at shutdown. If unsuccessful, print the exception.
    webserver.thenAccept(ws -> {
        System.out.println("WEB server is up! http://localhost:" + ws.port() + "/greet");
        ws.whenShutdown().thenRun(() -> System.out.println("WEB server is DOWN. Good bye!"));
    }).exceptionallyAccept(t -> {
        System.err.println("Startup failed: " + t.getMessage());
        t.printStackTrace(System.err);
    });
    return webserver;
}

Example 9 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class SignatureExampleUtil method startServer.

/**
 * Start a web server.
 *
 * @param routing routing to configre
 * @return started web server instance
 */
public static WebServer startServer(Routing routing, int port) {
    WebServer server = WebServer.builder(routing).port(port).build();
    long t = System.nanoTime();
    CountDownLatch cdl = new CountDownLatch(1);
    server.start().thenAccept(webServer -> {
        long time = System.nanoTime() - t;
        System.out.printf("Server started in %d ms ms%n", TimeUnit.MILLISECONDS.convert(time, TimeUnit.NANOSECONDS));
        System.out.printf("Started server on localhost:%d%n", webServer.port());
        System.out.println();
        cdl.countDown();
    }).exceptionally(throwable -> {
        throw new RuntimeException("Failed to start server", throwable);
    });
    try {
        cdl.await(START_TIMEOUT_SECONDS, TimeUnit.SECONDS);
    } catch (InterruptedException e) {
        throw new RuntimeException("Failed to start server within defined timeout: " + START_TIMEOUT_SECONDS + " seconds");
    }
    return server;
}

Example 10 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method routingAsFilter.

/**
 * All routing rules (routes) are evaluated in a definition order. The {@link Handler} assigned with the first valid route
 * for given request is called. It is a responsibility of each handler to process in one of the following ways:
 * <ul>
 *     <li>Respond using one of {@link io.helidon.webserver.ServerResponse#send() ServerResponse.send(...)} method.</li>
 *     <li>Continue to next valid route using {@link io.helidon.webserver.ServerRequest#next() ServerRequest.next()} method.
 *     <i>It is possible to define filtering handlers.</i></li>
 * </ul>
 * <p>
 * If no valid {@link Handler} is found then routing respond by {@code HTTP 404} code.
 * <p>
 * If selected {@link Handler} doesn't process request than the request <b>stacks</b>!
 * <p>
 * <b>Blocking operations:</b><br>
 * For performance reason, {@link Handler} can be called directly by a selector thread. It is not good idea to block
 * such thread. If request must be processed by a blocking operation then such processing should be deferred to another
 * thread.

public void routingAsFilter() {
    Routing routing = Routing.builder().any((req, res) -> {
        System.out.println(req.method() + " " + req.path());
        // Filters are just routing handlers which calls next()
        req.next();
    }).post("/post-endpoint", (req, res) -> res.status(Http.Status.CREATED_201).send()).get("/get-endpoint", (req, res) -> res.status(Http.Status.NO_CONTENT_204).send("Hello World!")).build();
