Osgi 对卡拉夫执行命令

我正在尝试运行一个PAX测试，它启动一个Karaf实例版本4.0.2，然后部署一些功能。到目前为止一切正常

但是，我还想运行一些命令来检查捆绑包是否已安装，即运行“bundle:list”命令

我添加了executeCommand和getOsgiService方法，可在此处找到：

但我得到了RuntimeException：

CommandProcessor的某些功能不工作。任何提示或帮助都将不胜感激。Thakns

使用Karaf 4.x时，命令确实发生了更改，因此您需要相应地进行更改。 可以找到完整的样本

作为快速总结，您需要在测试中使用SessionFactory，请参见以下内容：

@Inject
protected SessionFactory sessionFactory;

并从此处创建会话对象：

@Before
public void setUpITestBase() throws Exception {
    session = sessionFactory.create(System.in, printStream, errStream);
}

我在测试的前一部分中这样做，以确保会话始终是新创建的

以下是执行命令的关键部分：

    String response;
    FutureTask<String> commandFuture = new FutureTask<String>(new Callable<String>() {
        public String call() {
            try {
                System.err.println(command);
                session.execute(command);
            } catch (Exception e) {
                e.printStackTrace(System.err);
            }
            printStream.flush();
            errStream.flush();
            return byteArrayOutputStream.toString();
        }
    });

    try {
        executor.submit(commandFuture);
        response = commandFuture.get(10000L, TimeUnit.MILLISECONDS);
    } catch (Exception e) {
        e.printStackTrace(System.err);
        response = "SHELL COMMAND TIMED OUT: ";
    }

谢谢，我现在就试试这个。这是否也意味着您不需要TestProbeBuilder方法？它可以工作！非常感谢你的帮助。我到处都找遍了，都没找到。谢谢，我现在就试试这个。这是否也意味着您不需要TestProbeBuilder方法？它可以工作！非常感谢你的帮助。我到处都搜索了，但没有结果。当我在上面运行时，我得到的是以下输出14:48:20.390[main]信息o.o.p.e.r.c.RemoteBundleContextClient-等待远程捆绑上下文。。在21001上名称：52be8a65-7121-49ab-af8d-03ec1bf5b0fb timout:[RelativeTimeout value=180000]用法：java[-options]类[args…]（执行类）或java[-options]-jar文件[args…]（执行jar文件）当我在上面运行时，我在输出14:48:20.390[main]以下信息o.o.p.e.r.c.RemoteBundleContextClient-正在等待远程捆绑上下文。。在21001上名称：52be8a65-7121-49ab-af8d-03ec1bf5b0fb timout:[RelativeTimeout value=180000]用法：java[-options]类[args…]（用于执行类）或java[-options]-jar文件[args…]（用于执行jar文件）
