配置本地仓库:

參考:http://blog.csdn.net/wobendiankun/article/details/25333113

启动karaf:

karaf_home/bin/karaf.bat

启动成功例如以下:

安装 mvn-hello-provider 到本地仓库

hello.java

package com.demo.hello;

public class Hello {
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Hello() {
		this.name="jack";
	}
	public void sayHi(){
		System.out.println("hi:\t"+this.name);
	}
	
}

pom.xml:

执行命令:

mvn clean install

安装 mvn-hello-consumer 到本地仓库

HelloClientActivator.java

package com.demo.hello.activator;


import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

import com.demo.hello.Hello;

public class HelloClientActivator implements BundleActivator{
	Hello hello;
	public void start(BundleContext context) throws Exception {
		hello=new Hello();
		hello.sayHi();
	}

	public void stop(BundleContext context) throws Exception {
		hello=null;
	}

}

pom.xml

执行命令:

mvn clean install

部署bundle到karaf

注意部署顺序

先部署,mvn-hello-provider,再mvn-hello-consumer

在karaf命令行中执行命令:

bundle:install -s mvn:com.demo.hello/mvn-hello-provider/0.0.1-SNAPSHOT

bundle:install -s mvn:com.demo.hello/mvn-hello-consumer/0.0.1-SNAPSHOT

执行结果:
