您可以简单地执行以下操作：
String line;
while ((line = in.readLine()) != null) {
\\Do stuff
}
这应该具有预期的行为.
编辑：
这是我在使用您的代码的评论中谈论的完整示例：
package javaapplication12;
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 SocketExample {
private ServerSocket middleman;
private int port = 8080;
private Socket client;
protected void createSocketServer()
{
try
{
while (true){
middleman = new ServerSocket(port);
client = middleman.accept();
middleman.close();
PrintWriter out = new PrintWriter(client.getOutputStream(),true);
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
String line;
while((line = in.readLine()) != null)
{
System.out.println("echo: " + line);
out.println("test");
}
}
}
catch(IOException e)
{
System.out.println(e);
}
}
public static void main(String[] args){
SocketExample test = new SocketExample();
test.createSocketServer();
}
}
)
