在 Karaf 错误上部署 Spring

Question

我正在尝试运行 Spring 在 karaf 上。

当我尝试运行时：

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 class 在那里。

当我尝试在 Karaf 4 中使用 Spring 4.x 到一个包中时，我遇到了同样的问题，大部分问题是因为包没有导入所有 spring 包，可能是插件 "maven-bundle-plugin" 根据语法分析导出必要的包，并且 spring 通过反射在运行时加载许多 classes。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 spring 包的
导出的包
- 捆绑：列表-t 0 | grep spring
- bundle:bundle:headers --no-uses 55
将软件包（如果需要，可以添加版本）添加到 pom 中插件 maven-bundle-plugin 配置中的 "Import-Package"。在我的例子中，我从 spring-core / spring-context / spring-beans 导入了所有包这样，你的包将导入所有包，所以我知道我是在我的 poc 中添加了比我需要的更多的包，但是当 spring class 在运行时加载时，很难确定你的应用程序将在所有场景中使用的所有 spring 包通过反射.

有了它，你的bundle就可以使用spring 4.x，但是你必须手动创建应用程序上下文，我在bean的定义中使用了参数"init-method"在蓝图定义中，我不喜欢它，但它有效，无论如何，我正在寻找更优雅的方式。
