Question

My Activator课程：

package com.package.actprovider;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceListener;
import org.osgi.framework.ServiceRegistration;
import com.package.Application;
import org.osgi.framework.ServiceEvent;

/**
* This class implements a simple bundle that utilizes the OSGi
* framework's event mechanism to listen for service events. Upontting 
* receiving a service event, it prints out the event's details.
**/

public class Activator implements BundleActivator , ServiceListener{
private ServiceRegistration registration;
//private Application application;

/**
 * Implements BundleActivator.start(). Prints
 * a message and adds itself to the bundle context as a service
 * listener.
 * @param context the framework context for the bundle.
**/

@Override
public void start(BundleContext context)
{
    System.out.println("Starting to listen for service events.++++");
    context.addServiceListener(this);

}

/**
 * Implements BundleActivator.stop(). Prints
 * a message and removes itself from the bundle context as a
 * service listener.
 * @param context the framework context for the bundle.
**/
@Override
public void stop(BundleContext context)
{
    context.removeServiceListener(this);
    System.out.println("Stopped listening for service events.");
}

/**
 * Implements ServiceListener.serviceChanged().
 * Prints the details of any service event from the framework.
 * @param event the fired service event.
**/
public void serviceChanged(ServiceEvent event)
{
    String[] objectClass = (String[])
        event.getServiceReference().getProperty("objectClass");

    if (event.getType() == ServiceEvent.REGISTERED)
    {
        System.out.println(
            "Ex1: Service of type " + objectClass[0] + " registered.");
    }
    else if (event.getType() == ServiceEvent.UNREGISTERING)
    {
        System.out.println(
            "Ex1: Service of type " + objectClass[0] + " unregistered.");
    }
    else if (event.getType() == ServiceEvent.MODIFIED)
    {
        System.out.println(
            "Ex1: Service of type " + objectClass[0] + " modified.");
    }
}

}

equinox容器读取的MANIFEST.MF文件：

Manifest-Version: 1.0
Bundle-Description: A bundle that displays messages at startup and whe
n service events occur
Bundle-Name: Service listener example
Bundle-Version: 1.0.0
Bundle-Activator: com.package.actprovider.Activator
Bundle-Vendor: Apache Felix
Import-Package: org.osgi.framework
Created-By: 1.8.0_101 (Oracle Corporation)

这里是Bundle-Activator：com.package.actprovider.Activator，但是在/ BOOT-INF / classes / package中创建的activator.class文件com.package.actprovider.Activator

请建议如何在osgi容器中添加spring-boot bundle

Answer 1

Spring boot和OSGi是互斥的。你可以在一定程度上使用弹簧，但即使这样也很糟糕。

因此，最佳做法是基于声明性服务或蓝图构建OSGi应用程序。你也可以看看Apache Karaf对JPA，servlets等技术的支持......

这比春季启动要多一点努力，但你应该能够解决同样的问题。

如何在Equinox OSGi Container中部署Spring Boot应用程序。获取BundleException：加载bundle activator
