我编写了以下程序。如您所见,我在创建 ObjectInputStream 对象 ois 后放置了一条打印消息。我有一个在端口 9090 上打开的服务器。从上面的 netstat 消息中可以看出
sudo netstat -al | grep 9090
tcp6 0 0 [::]:9090 [::]:* LISTEN
我不知道为什么屏幕上会显示打印消息。

try {
/*

*/
InetAddress address = InetAddress.getByName("localhost");
Socket socket = new Socket(address, 9090);
/*

*/
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
System.out.println("Created client socket and Input Stream Reader");
while (true) {
if (count < 1000) {
String message = (String) ois.readObject();
System.out.println("OFMessage: " + message);
count++;
} else {
break;
}
}
ois.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
