将一个Bundle注册为服务

1、创建业务接口类及其实现类

public interface Validator {
	public boolean validate(String username, String password)throws Exception;
}

 

public class UserValidatorImpl implements Validator {
	public boolean validate(String username, String password) throws Exception {
		if("admin".equals(username) && "admin".equals(password)){
			return true;
		}
		return false;
	}
}

 

2、创建Bundle的激活器类

public class UserValidatorActivator implements BundleActivator {
	private ServiceRegistration serviceRegistration;
	
	public void start(BundleContext context) throws Exception {
		Validator obj = new UserValidatorImpl();
		serviceRegistration = context.
			registerService(Validator.class.getName(), obj, props); //注册服务
	}

	public void stop(BundleContext context) throws Exception {
		serviceRegistration.unregister(); //卸载服务
	}
}

 

3、MANIFEST.MF文件内容

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: UserValidatorBundle
Bundle-SymbolicName: UserValidatorBundle
Bundle-Version: 1.0.0
Bundle-Activator: com.cjm.bundle.user.activator.UserValidatorActivator
Bundle-Vendor: RIAWork
Import-Package: org.osgi.framework;version="1.3.0"
Export-Package: com.cjm.bundle.user.service;version="1.0.0"

 

4、打包Bundle后，执行install命令安装Bundle，执行start命令启动Bundle

 

5、可以执行services命令查看被注册的服务：
