我也來玩OSGI(四)

新建一個叫 ConfigFileLoginBundle 的Equinox 項目

 

 

文件結構如圖所示,我們要在 META-INF/MANIFEST.MF 中的 依賴 選項卡中選擇導入 org.vwpolo.services 這個包

package org.vwpolo.login.service;

import java.util.Hashtable;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceRegistration;
import org.vwpolo.login.service.impl.ConfigFileLoginServiceImpl;
import org.vwpolo.services.LoginService;

public class ConfigFileActivator implements BundleActivator ...{

    private BundleContext context = null;
    private ServiceRegistration serviceRegistration = null;
    private LoginService loginServiceImpl;

    /**//*
     * (non-Javadoc)
     * 
     * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)
     */
    public void start(BundleContext context) throws Exception ...{
        this.context = context;
        loginServiceImpl = new ConfigFileLoginServiceImpl();
        serviceRegistration = this.context.registerService(LoginService.class.getName(), loginServiceImpl, new Hashtable());
    }

    /**//*
     * (non-Javadoc)
     * 
     * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)
     */
    public void stop(BundleContext context) throws Exception ...{
        serviceRegistration.unregister();
        context = null;
    }

}

 

package org.vwpolo.login.service.impl;

import org.vwpolo.services.LoginService;

/** *//**
 * @author vwpolo
 *
 */
public class ConfigFileLoginServiceImpl implements LoginService...{

    @Override
    public boolean login(String userName, String password) ...{
        System.out.println("ConfigFile 登陸方式");
        if(userName.equals("vwpolo") && password.equals("123"))
            return true;
        return false;
    }

}
