【问题描述】:
我正在串联系统(Unix 环境)中部署我的应用程序。我正在尝试使用 TCP 连接到其他应用程序。我有一个 IP 地址和端口号。从客户端(我的应用程序),我正在写入数据,看起来它正在工作(没有收到任何异常),但是在读取数据时,我收到了 ReadTimeOutException。以下是我的程序,我将感谢您的帮助。有相同的应用程序返回是 C++ 它在相同的 IP 地址和端口号下工作正常
Socket clientSocket = new Socket();
clientSocket.setKeepAlive(true);
clientSocket.setReuseAddress(true);
clientSocket.setTcpNoDelay(true);
clientSocket.setSoTimeout(120000);
clientSocket.setSendBufferSize(65535);
clientSocket.connect(new InetSocketAddress("Server IP", "Port Number"), 1000);
OutputStream outstream = clientSocket.getOutputStream();
outstream .writeInt(msgLen);
dout.write(msg, 0, msgLen);
dout.flush();
DataInputStream dis = new DataInputStream(clientSocket.getInputStream());
int len = din.readInt();
data = new byte[len];
dis .readFully(data);
它在阅读时抛出错误。 尝试建立套接字连接时超时。 java.net.SocketTimeoutException: 读取超时
============================
Socket clientSocket = new Socket();
clientSocket.setKeepAlive(true);
clientSocket.setReuseAddress(true);
clientSocket.setTcpNoDelay(true);
clientSocket.setSoTimeout(120000); // Should wait 3 minutes before throwing time out exception - Actually throwing after 2 minutes
clientSocket.setSendBufferSize(65535);
InputStream in= new ObjectInputStream(socket.getInputStream());
OutputStream out = new ObjectOutputStream(socket.getOutputStream());
out.write(byteArray);
out.flush();
// Receive the same string back from the server
int totalBytesRcvd = 0; // Total bytes received so far
int bytesRcvd; // Bytes received in last read
while (totalBytesRcvd < byteArray.length) {
if ((bytesRcvd = in.read(byteArray, totalBytesRcvd,
byteArray.length - totalBytesRcvd)) == -1)
throw new SocketException("Connection close prematurely");
totalBytesRcvd += bytesRcvd;
}
clientSocket .close(); // Close the socket and its streams
请帮我解决这个问题,从上周开始我就被困在这个问题上。
谢谢!!!!
