Question

Java：1.7 操作系统：Linux（但我不知道它是哪个Linux）

我有一个CharBuffer来包含我从socket的BufferedReader中读取的东西。 Socket建立了肯定，当我试图转储它时，它给了我一个 ERROR_FORMAT 结果。

之后，我从套接字读取数据但导致 java.net.SocketException：连接重置

连接重置问题是我修复的问题，但 CharBuffer.toString（）如何提供 ERROR_FORMAT 结果？

以下是我的代码，有什么不对吗？

Socket connectionSocket=xxxxxx;  //Connected socket given by other library

connectionSocket.setSoTimeout(75*1000);
CharBuffer charBuffer=CharBuffer.allocate(1024);
BufferedReader bufferedReader=null;

bufferedReader=new BufferedReader(new InputStreamReader(connectionSocket.getInputStream(), "BIG5"));

while((bufferedReader.read(charBuffer))!=-1)  // in 2nd time, this line throw a java.net.SocketException: Connection reset
{
  charBuffer.flip();
  respStr.append(charBuffer);
  log.info("CharBuffer: "+charBuffer.toString());  // this line runs just 1 tine, print result: "CharBuffer: 2016102618353211301 : ERROR_FORMAT"
  charBuffer.clear();
}
log.info("CharBuffer all: "+charBuffer.toString());  // dodn't been execute

我无法复制您的问题

public static void main(String[] args) throws IOException {
    StringBuilder respStr = new StringBuilder();
    CharBuffer charBuffer=CharBuffer.allocate(1024);
    BufferedReader bufferedReader=null;
    Logger log = Logger.getAnonymousLogger();

    // create a byte stream with some big 5 characters in it
    // to simulate what a socket should produce
    byte[] bytes = new byte[100];
    int index = 0;
    for(int i = 0xc940;i<0xc940+50;i++){
        bytes[index++] = (byte)((i & 0x0ff00)>>8);
        bytes[index++] = (byte)((i & 0x0ff));
    }
    InputStream byteStream = new ByteArrayInputStream(bytes);

    // code to process the byte stream
    bufferedReader=new BufferedReader(new InputStreamReader(byteStream, "BIG5"));
    while((bufferedReader.read(charBuffer))!=-1){
        charBuffer.flip();
        respStr.append(charBuffer);
        log.info("CharBuffer: "+charBuffer.toString());
        charBuffer.clear();
    }
    log.info("CharBuffer all: "+charBuffer.toString());
}
