9.1.4、QQ登陆聊天功能（私聊群发）

9.1.4.1、私聊功能

1、需求说明

2、思路分析

3、代码实现
QQClient：
1）cn.com.agree.qqclient.QQView.QQView

  case "3":log.debug("请输入想给谁发消息(在线用户):");String getterId = Utility.readString(50).trim();log.debug("请输入想说的话:");content = Utility.readString(200).trim();//TODO 私聊bug invalid type code: AC已解决    messageClientService.sendMsgToOne(getterId,userId,content);                                        

2）cn.com.agree.qqclient.message.MessageClientService

 /*** 私聊* @param getterId 接收方id* @param senderId 发送方id* @param content  消息内容*/public void sendMsgToOne(String getterId,String senderId,String content){//创建Message对象Message message = new Message();message.setMsgType(MessageType.MESSAGE_COMM_MS);//对话，普通消息message.setGetter(getterId);message.setSender(senderId);message.setContent(content);message.setSendTime(new Date().toString());log.debug(senderId+" 对 "+getterId+" 说: "+content);//获取socket流发送message消息try {ObjectOutputStream oos = new MyObjectOutputStream(ManageClientConnectServers.getClientConnectServer(senderId).getSocket().getOutputStream());oos.writeObject(message);} catch (IOException e) {e.printStackTrace();}}

3）cn.com.agree.qqclient.service.ClientConnectServer

  case MessageType.MESSAGE_COMM_MS:log.debug(message.getSender()+" 对 "+message.getGetter()+" 说: "+message.getContent());break;

QQServer：
1）cn.com.agree.qqserver.service.ServerConnectClient

 case MessageType.MESSAGE_COMM_MS:log.debug("message:{}", message);log.debug(message.getSender() + " 对 " + message.getGetter() + " 说: " + message.getContent());//转发消息ObjectOutputStream oos2 = new MyObjectOutputStream(ManageServerConnectClient.getServerConnectClient(message.getGetter()).getSocket().getOutputStream());oos2.writeObject(message);//如果用户不在线，可以保存到数据库做离线转发break;

4、运行效果

9.1.4.2、群发功能

1、需求说明

2、思路分析

3、代码实现
Common：
cn.com.agree.qqcommon.MessageType

String MESSAGE_ONLINEAll_MS="7";//群发消息

QQClient：
1）cn.com.agree.qqclient.QQView.QQView

 case "2"://TODO 群发bug invalid type code: AC待解决log.debug("请输入要说的内容:");String content = Utility.readString(100);messageClientService.sendMsgToAll(userId,content);// System.out.println("群发消息");break;

2）cn.com.agree.qqclient.message.MessageClientService

 /*** 群发* @param* @param senderId 发送方id* @param content  消息内容*/public void sendMsgToAll(String senderId,String content){//创建Message对象Message message = new Message();message.setMsgType(MessageType.MESSAGE_ONLINEAll_MS);//对话，普通消息message.setSender(senderId);message.setContent(content);message.setSendTime(new Date().toString());log.debug(senderId+" 对 "+"大家说: "+content);//获取socket流发送message消息try {ObjectOutputStream oos = new MyObjectOutputStream(ManageClientConnectServers.getClientConnectServer(senderId).getSocket().getOutputStream());oos.writeObject(message);} catch (IOException e) {e.printStackTrace();}}

3）cn.com.agree.qqclient.service.ClientConnectServer

 case MessageType.MESSAGE_ONLINEAll_MS:log.debug(message.getSender() + " 对 " +"大家说: " + message.getContent());break;

QQServer：
cn.com.agree.qqserver.service.ServerConnectClient

case MessageType.MESSAGE_ONLINEAll_MS:log.debug("message:{}", message);log.debug(message.getSender() + " 对 " + "大家说: " + message.getContent());//遍历服务端线程集合获取非发送方的线程socket进行消息转发Map<String, ServerConnectClient> hm = ManageServerConnectClient.getHm();Iterator<String> userIds = hm.keySet().iterator();while (userIds.hasNext()) {String userId = userIds.next().toString();if (!userId.equals(message.getSender())) {//获取非发送方的用户idServerConnectClient serverConnectClient = hm.get(userId);//获取socket进行消息转发ObjectOutputStream oos3 = new MyObjectOutputStream(serverConnectClient.getSocket().getOutputStream());oos3.writeObject(message);}}break;

4、运行结果

public class MyObjectInputStream extends ObjectInputStream {public MyObjectInputStream(InputStream in) throws IOException {super(in);}@Overrideprotected void readStreamHeader() throws IOException {//重写读取头部信息方法：什么也不做}}

cn.com.agree.stream.MyObjectOutputStream

package cn.com.agree.stream;import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.OutputStream;/*** @author * @version 1.0* @ClassName AppendObjectOutputStream* @Description TODO 类描述* @date 2024/1/11  9:46 上午**/
