java输入输出流问题readline

Question

public class server {
public static void main(String[] args) throws IOException{
int portNumber = 12009;
ServerSocket serverSocket = null;
try{
serverSocket = new ServerSocket(portNumber);
Socket clientSocket = serverSocket.accept();
System.out.println("client comes in," + clientSocket.getInetAddress());

        BufferedReader in = new BufferedReader (new InputStreamReader(
                clientSocket.getInputStream()));

        String inputLine =null;
        inputLine = in.readLine();//代码被卡在这个地方，执行不了。
        System.out.println("client comes in," + clientSocket.getInetAddress());
        System.out.println(inputLine == null ? 1 : 0);
        while((inputLine = in.readLine()) != null){
            System.out.println(inputLine);
            if(inputLine.equals("1"))
            {
                new ServerTest2();
            }
            System.out.println("recv from client:" + inputLine);
        }
    }catch(Exception e){
        e.printStackTrace();
    }finally{
        if(serverSocket!=null)
            serverSocket.close();
    }
}

}
这是一个server程序，想读出来发过来的1，但是读不出来，上面那句println读不出来
