OSGI DS 实例

 一，开发生产者：

    工程名：org.vwpolo.osgi.service

    声明接口：

 package org.vwpolo.osgi.service.model;

public interface LoginService {
 public void login(String name,String password);

}

 

实现：

 package org.vwpolo.osgi.service.model.impl;

import org.vwpolo.osgi.service.model.LoginService;

public class LoginServiceImpl implements LoginService {

 @Override
 public void login(String name, String password) {
  // TODO Auto-generated method stub
  if("lxj".equals(name)&&password.equals("123")){
   System.out.println("登录成功");
   
  }else
   System.out.println("Sorry,用户名或密码有错误码");

 }

}
