求助java socket接收数据的问题

Question

我用如下代码：
BufferedReader socketReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String recvMsg = socketReader.readLine();
发送的字符串是:“123456\nabcd”
用这种方法遇到"\n"符号会认为是结束符，接收终止了，后续的字母“abcd”不会接收到，请问用什么办法能够一次性接收所有的字符？多谢了！

不要用readLine(),直接按字节读socket.inputStream();
