如何在Java中將多個對象發送到套接字

Question

任何人都可以請指教如何通過套接字將多個序列化的對象以java的形式發送到服務器？
目前我的服務器始終只有第一個對象。

客戶端：

public void communicate() throws UnknownHostException, IOException { 
    carClientSocket = new Socket("localhost", 4444); 
    carClientOR = new ObjectOutputStream(carClientSocket.getOutputStream()); 

    Car[] CarList = new Car[11]; 
    for (int i = 1; i <=10; i++) { 
     //Car alpha; 
     CarList[i] = new Car("Alpha Romeo","GTI",1999+i); 
    } 
    for (int i =1; i<= 10; i++) { 
     carClientOR.writeObject(CarList[i]); 
     carClientOR.flush(); 
     //carClientOR.reset(); 
    } 
    carClientSocket.close(); 
} 

服務器端

public void communicate() throws IOException, ClassNotFoundException { 
CarServerSocket = new ServerSocket(4444); 
    System.out.println("Server is ready and waiting for connection from client..\n"); 
    while (true) { 
     carSocket = CarServerSocket.accept(); 
     System.out.println("Server Connected"); 
     carServerIR = new ObjectInputStream(carSocket.getInputStream()); 
     Car alpha1 = (Car) carServerIR.readObject(); 
     System.out.println("Object received from car clinet: " + alpha1.getCarBrad() + " " + alpha1.getCarModel() + " " + alpha1.getCarYear()); 
    } 
    //carSocket.close(); 
    //CarServerSocket.close(); 
} 

Answer 1

的問題是在服務器端，由於是在循環中調用carSocket = CarServerSocket.accept();。它應該在循環之前完成一次，然後你應該得到其他對象：

carSocket = CarServerSocket.accept(); 
while (true) { 
    System.out.println("Server Connected"); 
    carServerIR = new ObjectInputStream(carSocket.getInputStream()); 
    Car alpha1 = (Car) carServerIR.readObject(); 
    System.out.println("Object received from car clinet: " + alpha1.getCarBrad() + " " + alpha1.getCarModel() + " " + alpha1.getCarYear()); 
}
