Examples with Args io.vertx.core.impl.Args used on opensource projects

Example 1 with Args

use of io.vertx.core.impl.Args in project vert.x by eclipse.

the class Starter method main.

public static void main(String[] sargs) {
    Args args = new Args(sargs);
    String extraCP = args.map.get("-cp");
    if (extraCP != null) {
        // If an extra CP is specified (e.g. to provide cp to a jar or cluster.xml) we must create a new classloader
        // and run the starter using that so it's visible to the rest of the code
        String[] parts = extraCP.split(PATH_SEP);
        URL[] urls = new URL[parts.length];
        for (int p = 0; p < parts.length; p++) {
            String part = parts[p];
            File file = new File(part);
            try {
                URL url = file.toURI().toURL();
                urls[p] = url;
            } catch (MalformedURLException e) {
                throw new IllegalStateException(e);
            }
        }
        ClassLoader icl = new URLClassLoader(urls, Starter.class.getClassLoader());
        ClassLoader oldTCCL = Thread.currentThread().getContextClassLoader();
        Thread.currentThread().setContextClassLoader(icl);
        try {
            Class<?> clazz = icl.loadClass(Starter.class.getName());
            Object instance = clazz.newInstance();
            Method run = clazz.getMethod("run", Args.class, String[].class);
            run.invoke(instance, args, sargs);
        } catch (Exception e) {
            throw new IllegalStateException(e);
        } finally {
            Thread.currentThread().setContextClassLoader(oldTCCL);
        }
    } else {
        // No extra CP, just invoke directly
        new Starter().run(args, sargs);
    }
}

Example 2 with Args

use of io.vertx.core.impl.Args in project vert.x by eclipse.

the class Starter method runVerticle.

private void runVerticle(String main, Args args) {
    boolean ha = args.map.get("-ha") != null;
    boolean clustered = args.map.get("-cluster") != null || ha;
    Vertx vertx = startVertx(clustered, ha, args);
    if (vertx == null) {
        // Throwable should have been logged at this point
        return;
    }
    String sinstances = args.map.get("-instances");
    int instances;
    if (sinstances != null) {
        try {
            instances = Integer.parseInt(sinstances);
            if (instances != -1 && instances < 1) {
                log.error("Invalid number of instances");
                displaySyntax();
                return;
            }
        } catch (NumberFormatException e) {
            displaySyntax();
            return;
        }
    } else {
        instances = 1;
    }
    String confArg = args.map.get("-conf");
    JsonObject conf;
    if (confArg != null) {
        try (Scanner scanner = new Scanner(new File(confArg)).useDelimiter("\\A")) {
            String sconf = scanner.next();
            try {
                conf = new JsonObject(sconf);
            } catch (DecodeException e) {
                log.error("Configuration file " + sconf + " does not contain a valid JSON object");
                return;
            }
        } catch (FileNotFoundException e) {
            try {
                conf = new JsonObject(confArg);
            } catch (DecodeException e2) {
                log.error("-conf option does not point to a file and is not valid JSON: " + confArg);
                return;
            }
        }
    } else {
        conf = null;
    }
    boolean worker = args.map.get("-worker") != null;
    String message = (worker) ? "deploying worker verticle" : "deploying verticle";
    deploymentOptions = new DeploymentOptions();
    configureFromSystemProperties(deploymentOptions, DEPLOYMENT_OPTIONS_PROP_PREFIX);
    deploymentOptions.setConfig(conf).setWorker(worker).setHa(ha).setInstances(instances);
    beforeDeployingVerticle(deploymentOptions);
    vertx.deployVerticle(main, deploymentOptions, createLoggingHandler(message, res -> {
        if (res.failed()) {
            handleDeployFailed();
        }
    }));
}

Example 3 with Args

use of io.vertx.core.impl.Args in project vert.x by eclipse.

    String[] sargs = commandLine.split(" ");
    Args args = new Args(sargs);
    run(args, sargs);
}
