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;

运行命令:


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;
	}

}

						<Bundle-Activator>com.demo.hello.activator.HelloClientActivator</Bundle-Activator>
					</instructions>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

运行命令:


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命令行中运行命令:


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


运行结果:


bubuko.com,布布扣
