如何检查Wildfly 8.2.1是否以编程方式正确部署了我的应用程序？

Question

I need to check the deployment status of my application which is deployed by Wildfly 8.2.1 programmatically (preferably java). As far I am concerned, there can be multiple ways to achieve this:

1. monitoring the semaphore files in the deployment folder (like if deployed there are .deployed files created for the war files).
2. check by calling a rest service which is supposed to be available when the war file is successfully deployed
3. using JMX mbeans

There might be other ways too, which I am not yet aware of. But I am more interested in learning the ways of using JMX mbeans . But unfortunately my online search is not giving me any good direction. If anyone can shed some light to this that would be really helpful.

You could use management operations to check to see if you're deployment exists. It's a little old, but there's a tutorial on the deypted API.

try (final ModelControllerClient client = ModelControllerClient.Factory.create(InetAddress.getLocalHost(), 9990)) {
    final ModelNode op = Operations.createOperation("read-children-resources");
    op.get(ClientConstants.CHILD_TYPE).set(ClientConstants.DEPLOYMENT);
    final ModelNode result = client.execute(op);
    if (Operations.isSuccessfulOutcome(result)) {
        final ModelNode deployments = Operations.readResult(result);
        for (String deploymentName : deployments.keys()) {
            final ModelNode deploymentDetails = deployments.get(deploymentName);
            // do stuff
        }
    } else {
        throw new RuntimeException("Failed to list deployments: " + Operations.getFailureDescription(result).asString());
    }
}

From the result you can read various information about the deployment. The output looks like:

{
    "content" => [{"hash" => bytes {
        0x77, 0x1f, 0x1a, 0xa1, 0x9e, 0x46, 0x11, 0x75,
        0x2f, 0x58, 0xce, 0x1b, 0x01, 0x29, 0x45, 0x43,
        0x16, 0x87, 0x22, 0x9a
    }}],
    "enabled" => true,
    "enabled-time" => 1443485828919L,
    "enabled-timestamp" => "2015-09-28 17:17:08,919 PDT",
    "name" => "batch-chunk.war",
    "owner" => undefined,
    "persistent" => true,
    "runtime-name" => "batch-chunk.war",
    "subdeployment" => undefined,
    "subsystem" => {
        "jaxrs" => undefined,
        "batch" => undefined,
        "undertow" => undefined
    }
}

If you wanted to see whether it was enabled you could do

if (!deploymentDetails.get("enabled")) {
    throw new RuntimeException(String.format("Deployment %s is not enabled", deploymentName);
}
