當使用BufferedOutputStreams時，ObjectInputStream不會初始化

Question

我試圖通過套接字發送遊戲對象，但是它們需要很長時間才能發送，並且可能導致遊戲掛起。我想使用BufferedOutputStreams和BufferedInputStreams來發送數據，但是當我在客戶端使用BufferedOutputStream時，我的ObjectInputStream不會在服務器端初始化。奇怪的是沒有錯誤拋出。

我只提供涉及的代碼，因爲這需要很長時間才能解釋發生了什麼。每場比賽都有兩名客戶進行初始化。

/*Server Code*/ 

ObjectOutputStream toClients;//stream to both players 
ObjectInputStream fromClients;//stream from both players 
Socket client1;//player one socket 
Socket client2;//player two socket 
public RunGame(Socket client1, Socket client2)throws IOException//constructor of a new thread 
{ 
    this.client1=client1; 
    this.client2=client2; 
} 
public void run()//for the thread 
{ 
    try{ 
     this.createGame(); 
     /* 
     rest of code for server when running game 
     */ 
    } 
    catch(IOException e){e.printStackTrace();} 
    catch(ClassNotFoundException e){e.printStackTrace();} 
} 
public void createGame() 
{ 
    try{ 
     System.out.println("about to create");//this prints out 
     fromClients=new ObjectInputStream(client1.getInputStream());//first initialization 

     System.out.println("created");//this doesn't 
     String s1=(String)fromClients.readObject(); 

     fromClients=new ObjectInputStream(client2.getInputStream());//sets input to player 2 
     String s2=(String)fromClients.readObject(); 
    } 
    catch(IOException e){e.printStackTrace();} 
    catch(ClassNotFoundException e){e.printStackTrace();} 
} 

/*Client Code*/ 
Socket sock;//created in the constructor of the thread 
ObjectOutputStream toServer; 
ObjectInputStream fromServer; 
public void run() 
{ 
    try{ 
    System.out.println("about to create");//this prints 
    toServer=new ObjectOutputStream(new BufferedOutputStream(sock.getOutputStream(),8*1024));//bufferedoutputstream is here 
    toServer.writeObject("String that is to be sent to server"); 
    System.out.println("written");//this also prints 
    } 
    catch(IOException e){e.printStackTrace();} 
    catch(ClassNotFoundException e){e.printStackTrace();} 
    /* 
    rest of client code 
    */ 
} 

我已經通過了所有的論壇，但找不到任何有效的工作，這讓我認爲我正在做一些非常新手。謝謝你提供的所有幫助！

您需要.flush()您的ObjectOutputStream否則BufferedOutputStream將不會將其輸出發送到套接字。
