服务器的代码：
package Day02;
import java.io.*;
import java.net.*;
public class Socket1 {
public static void main(String[] args) throws Exception{
int port=8899;
ServerSocket server=null;
MChat MC=new MChat();
try {
server=new ServerSocket(port);
System.out.println("服务器启动...");
while(true) {
Socket socket=server.accept();//监听客户端连接，如果客户端连接成功，返回实例化的Socket对象
System.out.println("客户端信息:"+socket);
//读取流操作
SocketThd thd=new SocketThd(socket);
thd.start();
}
} catch (Exception e) {
// TODO: handle exception
}
finally {
try {
if(server!=null)
server.close();
System.out.println("服务器已停止！ ");
} catch (Exception e2) {
// TODO: handle exception
}
}
}
static class SocketThd extends Thread{
MChat MC=new MChat();
Socket socket;//和客户端进行通信的对象
BufferedReader br=null;
PrintWriter pw=null;
public SocketThd(Socket socket) {
this.socket=socket;
}
public void run() {
//读入流操作
try {
br=new BufferedReader(new InputStreamReader(socket.getInputStream(),"UTF-8"));
//写入流操作
pw=new PrintWriter(
new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF-8")));
//接收客户端发送来的信息
String str="";
while((str=br.readLine())!=null) {
System.out.println("客户端："+str);
//服务器处理
String rtn="";
//聊天机器人处理程序
rtn=MC.getCharResult(str);
//处理结果返回客户端
pw.println(rtn);
pw.flush();
}
}
catch (Exception e) {
e.printStackTrace();
}
finally {
// TODO: handle finally clause
try {
if(br!=null) br.close();
if(pw!=null) pw.close();
if(socket!=null) socket.close();
} catch (Exception e2) {
// TODO: handle exception
}
}
}
}
}客户端的代码：
package Day02;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.Socket;
public class Client1 {
public static void main(String[] args) throws Exception{
String IP="192.168.1.*";
int port=8899;
Socket socket=new Socket(IP,port);//建立与服务器连接
//读取流操作
BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream(), "UTF-8"));
BufferedReader brKey=new BufferedReader(new InputStreamReader(System.in, "UTF-8"));
//写入流操作
PrintWriter pw=new PrintWriter(
new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF-8")));
while(true) {
String send=brKey.readLine();//等待阻塞命令
if(send.equals("END")) {//键盘输入的借宿条件
break;
}
//向服务器发送信息
pw.println(send);
pw.flush();
//接收服务端回复的消息
String strRtn=br.readLine();
System.out.println("服务端回复信息："+strRtn);
}
//关闭连接
br.close();
pw.close();
socket.close();
}
}对话内容引擎：
package Day02;
import java.util.Hashtable;
public class MChat {
private Hashtable<String, String> htMS=new Hashtable<>();
public String getCharResult(String sKey) {
String str=htMS.get(sKey);
if(str==null)
return "";
else
return str;
}
public MChat() {
htMS.put("你好呀","你也好呀，你需啊什么服务吗？");
htMS.put("见到你很高兴","我也很高兴见到你。");
htMS.put("吃了吗","今天吃的好饱呀");
htMS.put("好累呀", "听音乐轻松一下吧");
htMS.put("路上好堵呀","需要哦给你选一条路线吗");
htMS.put("再见", "我先走了，有事你叫我");
}
}实现结果如下：
