Question

我有一个jerey（2.26）webapplication。我的目的是监听应用程序事件，例如＆＃34;应用程序已初始化＆＃34;或者＆＃34;应用程序被销毁＆＃34;并启动|停止外部数据库连接。这里有一个基本概述（https://jersey.github.io/documentation/latest/monitoring_tracing.html）。为此，我使用 ApplicationEventListener 界面并注册其实现的类 ＆＃34; MyApplicationEventListener＆＃34; 作为提供者。我在 wildfly-10.1.0.Final 上部署它，似乎wildfly运行时可以识别 MyApplicationEventListener 作为提供者

但是没有记录或捕获任何应用程序事件？

我使用web.xml少部署。所以我的所有应用程序都是基于注释的。以下是我使用的代码片段。 Wildfly服务器日志

的build.gradle

dependencies {
    compile 'javax:javaee-api:7.0'
    compile 'org.mongodb:mongodb-driver:3.5.0'
    compile 'javax.ws.rs:javax.ws.rs-api:2.0'

    testCompile 'org.testng:testng:6.10'
    testCompile 'org.mockito:mockito-core:2.+'
}

应用程序类（我也使用过jersey的ResourceConfig。但没有运气）

@ApplicationPath(value = "/apiHub")
public class AppConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {

        final Set<Class<?>> classes = new HashSet<>();
        // register root resource
        classes.add(AccountService.class);
        classes.add(MyApplicationEventListener.class);
        return classes;

    }

    public Map<String, Object> getProperties() {
        final Map<String, Object> properties = new HashMap<String, Object>();
        // Enable Tracing support.
        properties.put(ServletProperties.JAXRS_APPLICATION_CLASS, "butterfly.v1.rest.AppConfig.class");
        properties.put(ServerProperties.APPLICATION_NAME, "Butterfly");
        properties.put(ServerProperties.TRACING, "ALL");
        properties.put(ServerProperties.MONITORING_ENABLED, true);
        properties.put(ServerProperties. MONITORING_STATISTICS_ENABLED, true);
        properties.put(ServerProperties.PROVIDER_PACKAGES, "butterfly.v1.rest");
        return properties;

    }
}

应用程序事件监听器类

public class MyApplicationEventListener implements ApplicationEventListener {
    private volatile int requestCnt = 0;

    @Override
    public void onEvent(ApplicationEvent event) {
        switch (event.getType()) {
            case INITIALIZATION_FINISHED:
                System.out.println("Application "+ event.getResourceConfig().getApplicationName()+ " was initialized.");
            break;
            case DESTROY_FINISHED:
                System.out.println("Application "+ event.getResourceConfig().getApplicationName() + "destroyed.");
            break;
            default:
                System.out.println("Default case");
                break;
        }
    }

    @Override
    public RequestEventListener onRequest(RequestEvent requestEvent) {
        requestCnt++;
        System.out.println("Request " + requestCnt + " started.");
        // return the listener instance that will handle this request.
        return new MyRequestEventListener(requestCnt);
    }
}

应用程序事件侦听器不在泽西上工作
