Question

我试图在karaf上运行Spring。

当我试图运行时：

public class SnifferActivator implements BundleActivator {

    @Override
    public void start(BundleContext bundleContext) throws Exception {
        System.out.println("Start");
       new Thread(new Sniffer()).start();
    }

    @Override
    public void stop(BundleContext bundleContext) throws Exception {

    }
}

  public class Sniffer implements Runnable{

            @Override
            public void run() {
            ApplicationContext context = new AnnotationConfigApplicationContext(SnifferConfig.class);
            }
    }

我收到以下错误消息：

karaf@root()> Exception in thread "Thread-305" java.lang.IllegalStateException:
Cannot load configuration class: com.emot.worker.configuration.SnifferConfig
        at org.springframework.context.annotation.ConfigurationClassPostProcesso
r.enhanceConfigurationClasses(ConfigurationClassPostProcessor.java:403)
        at

我检查了我在Karaf上部署的包，这个类就在那里。

当我尝试将Spring 4.x用于Karaf 4中的捆绑包时，我遇到了同样的问题，因为捆绑包没有导入所有Spring包，可能是插件＆＃ 34;行家束-插件＆＃34;基于语法分析导出必要的包，并通过反射在运行时弹出许多类。这些是我的步骤：

在Karaf 4.x中安装Spring 4.x
- 功能：安装spring / 4.3.12.RELEASE_1
列出弹簧束导出的包
- bundle：list -t 0 | grep spring
- bundle：bundle：headers --no-uses 55
将包（如果需要，带有版本）添加到＆＃34; Import-Package＆＃34;在您的pom中的插件maven-bundle-plugin的配置中。在我的例子中，我从spring-core / spring-context / spring-beans导入了所有包。这样，你的bundle会导入所有的包，所以我知道我在我的poc中添加了比我需要的更多的包，但是它＆＃39;在运行时通过反射加载spring类时，很难确定应用程序将在所有场景中使用的所有spring包。

有了这个，你的bundle可以使用spring 4.x，但是你必须手动创建应用程序上下文，我使用参数＆＃34; init-method＆＃34;在蓝图定义中的bean的定义中，我不喜欢它，但无论如何，它都有效，我正在寻找一种更优雅的方式。
