JAVA网络编程样例

这篇文章主要用来总结Java在网络编程中的知识点
下面是一个Java客户端与服务端通信的样例程序
//Server
public class Server {
public static void main(String[] args) throws IOException {
ServerSocket ss = new ServerSocket(6666);
System.out.println("Server start listening...");
for (; ; ) {
Socket sock = ss.accept();
System.out.println("Receviced package from " + sock.getRemoteSocketAddress());
Thread t = new Handler(sock);
t.start();
}
}
}
class Handler extends Thread {
Socket sock;
public Handler(Socket sock) {
this.sock = sock;
}
@Override
public void run() {
try (InputStream input = this.sock.getInputStream()) {
try (OutputStream output = this.sock.getOutputStream()) {
handle(input, output);
}
} catch (Exception e) {
try {
this.sock.close();
} catch (IOException ioe) {
}
System.out.println("Client disconnected.");
}
}
private void handle(InputStream input, OutputStream output) throws IOException {
var writer = new BufferedWriter(new OutputStreamWriter(output, StandardCharsets.UTF_8));
var reader = new BufferedReader(new InputStreamReader(input, StandardCharsets.UTF_8));
writer.write("hello\n");
writer.flush();
for (; ; ) {
String s = reader.readLine();
if (s.equals("bye")) {
writer.write("bye\n");
writer.flush();
break;
}
writer.write("ok: " + s + "\n");
writer.flush();
}
}
}
//client
public class client {
public static void main(String[] args) throws IOException {
Socket sock = new Socket("localhost", 6666);
try (InputStream input = sock.getInputStream()){
try(OutputStream output = sock.getOutputStream()){
handle(input, output);
}
}
}
private static void handle(InputStream input, OutputStream output) throws IOException{
var writer = new BufferedWriter(new OutputStreamWriter(output, StandardCharsets.UTF_8));
var reader = new BufferedReader(new InputStreamReader(input, StandardCharsets.UTF_8));
Scanner scanner = new Scanner(System.in);
System.out.println("[server]: "+ reader.readLine());
for(;;){
System.out.print(">>>");
String s = scanner.nextLine();
writer.write(s);
writer.newLine();
writer.flush();
String resp = reader.readLine();
System.out.println("<<<" + resp);
if(resp.equals("bye")) break;
}
}
}
实现功能为服务端与客户端相互通信，收到bye信号后断开连接，如图所示
