通过套接字发送的字符串中的最后几个字符有时在 Java 网络程序中丢失

Im pretty sure the error is happening when I read over the network. The read takes place in its own thread, with a BufferedReader wrapped around the socket's InputStream, and looks like this:

try {
        int input;
        while((input = dataIn.read()) != -1 ){
            char msgChar = (char)input;
            String message = msgChar + "";
           while(dataIn.ready()){
               msgChar = (char)dataIn.read();
               message+= msgChar;
           }
           System.out.println("Just received " + message);
           this.processMessage(message);

        }
        this.sock.close();


    } 

我的 sendMessage 方法非常简单，(只是对包裹在套接字输出流周围的 DataOutputStream 进行写入)所以我认为问题不会发生在那里:

try {
        dataOut.writeBytes(message);
        System.out.println("Just sent " + message);
    }
