我試圖創(chuàng)建一個客戶端-服務(wù)器應(yīng)用程序，其中客戶端生成一個隨機數(shù)并向服務(wù)器發(fā)送 n 個字符串。連接關(guān)閉發(fā)送字符串“BYE”。之后服務(wù)器必須計算接收到的字符串的總長度并打印出來。問題是，當我的客戶端嘗試連接到服務(wù)器時，此客戶端拋出“java.net.SocketException：連接重置”異常并崩潰。這是我的客戶代碼：import java.net.*;import java.io.*;import java.util.Random;import java.util.logging.Level;import java.util.logging.Logger;public class ClientStringa { public static void main(String[] args) { try{ Socket socket = new Socket("localhost", 5555); PrintWriter out = new PrintWriter(socket.getOutputStream()); Random r = new Random(); int N = r.nextInt(100); for(int i=1;i<=N;i++){ out.println("String" +i); } out.flush(); } catch (IOException ex) { Logger.getLogger(ClientStringa.class.getName()).log(Level.SEVERE, null, ex); } }}我的服務(wù)器代碼：import java.io.*;import java.net.*;import java.util.logging.Level;import java.util.logging.Logger;public class ServerStringa { public static void main(String[] args) { try { ServerSocket socket = new ServerSocket(5555); while(true){ System.out.println("Waiting for client connections..."); Socket client = socket.accept(); //connessione dei client ThreadStringa thread = new ThreadStringa(client); thread.start(); } } catch (IOException ex) { Logger.getLogger(ServerStringa.class.getName()).log(Level.SEVERE, null, ex); } } }

在socket編程中，應(yīng)該使用DataOutputStream而不是客戶端程序中的PrintWriter來與Server通信。還要記住從客戶端執(zhí)行 close() 。我只修改了你的客戶端程序，你可以檢查一下。
import java.net.*;
import java.io.*;
import java.util.Random;
import java.util.logging.Level;
import java.util.logging.Logger;
public class ClientStringa {
public static void main(String[] args) {
try{
Socket socket = new Socket("localhost", 5555);
DataOutputStream out=new DataOutputStream(socket.getOutputStream());
// PrintWriter out = new PrintWriter(socket.getOutputStream());
Random r = new Random();
int N = r.nextInt(100);
for(int i=1;i<=N;i++){
// out.println("String" +i);
out.writeUTF("String" +i);
}
out.flush();
out.close();
}
catch (IOException ex) {
Logger.getLogger(ClientStringa.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
