在Java中,對Socket連接進行狀態監控可以通過以下幾個步驟實現:
SocketListener
接口的類,并重寫其中的方法,如socketCreated()
、socketConnected()
、socketDisconnected()
、dataReceived()
等。這些方法會在Socket連接的不同狀態發生時被調用。import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketListener;
public class MySocketServer implements SocketListener {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = new ServerSocket(8080);
serverSocket.setSocketListener(new MySocketServer());
serverSocket.accept();
}
@Override
public void socketCreated(Socket socket) {
System.out.println("Socket created: " + socket);
}
@Override
public void socketConnected(Socket socket) {
System.out.println("Socket connected: " + socket);
}
@Override
public void socketDisconnected(Socket socket) {
System.out.println("Socket disconnected: " + socket);
}
@Override
public void dataReceived(Socket socket, String data) {
System.out.println("Data received from " + socket + ": " + data);
}
}
socketConnected()
方法中,為每個新建的Socket連接創建一個新的線程,以便在單獨的線程中處理客戶端的請求。這樣可以確保服務器能夠同時處理多個客戶端連接。@Override
public void socketConnected(Socket socket) {
System.out.println("Socket connected: " + socket);
new Thread(() -> {
try {
// Handle client request
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
isConnected()
和isClosed()
方法來檢查Socket是否仍然連接或已關閉。// Inside the thread handling client request
while (socket.isConnected()) {
// Read data from socket
// Process data
// Check if the connection is still alive
if (!socket.isConnected() || socket.isClosed()) {
System.out.println("Connection closed or lost: " + socket);
break;
}
}
通過以上步驟,可以實現對Java中Socket連接的狀態監控。請注意,這里的示例僅用于演示目的,實際應用中可能需要根據具體需求進行調整。
