在Java中實(shí)現(xiàn)服務(wù)器端打印功能可以通過(guò)以下步驟來(lái)實(shí)現(xiàn):
以下是一個(gè)簡(jiǎn)單的服務(wù)器端打印功能的示例代碼:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class ServerExample {
public static void main(String[] args) {
try (ServerSocket serverSocket = new ServerSocket(8080)) {
System.out.println("Server started...");
Socket clientSocket = serverSocket.accept();
System.out.println("Client connected...");
BufferedReader reader = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
PrintWriter writer = new PrintWriter(System.out, true);
String line;
while ((line = reader.readLine()) != null) {
System.out.println("Client: " + line);
writer.println("Server received: " + line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
在上面的示例代碼中,服務(wù)器端創(chuàng)建了一個(gè)ServerSocket,并且監(jiān)聽(tīng)端口為8080。當(dāng)客戶端連接后,服務(wù)器端會(huì)打印"Client connected…",然后會(huì)讀取客戶端發(fā)送的數(shù)據(jù),并在控制臺(tái)打印出來(lái),并向客戶端發(fā)送一條確認(rèn)消息。
通過(guò)這樣的方式,服務(wù)器端就可以實(shí)現(xiàn)打印客戶端發(fā)送的數(shù)據(jù)的功能。
