问题描述
我写了一个简单的服务器和客户端示例,如下所示。
I wrote a simple server and client example as below .
客户端:
- 打开连接
- 获取outputstream,写入流并关闭输出流
-
获取inputstream并从流中读取。此时获取异常
- Open a connection
- Get outputstream , write to stream and close the output stream
Get inputstream and read from the stream. Getting exception at this point
public class DateServer {
public static void main(String[] args) throws InterruptedException {
ServerSocket serverSocket = null;
Socket client = null;
try {
serverSocket = new ServerSocket(6013);
while (true) {
client = serverSocket.accept();
OutputStream outputStream = client.getOutputStream();
InputStream inputStream = client.getInputStream();
System.out.println("" + outputStream + "-" + inputStream);
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(inputStream));
String line = null;
while ((line = bufferedReader.readLine()) != null) {
System.out
.println("Message recieved from client ::" + line);
}
PrintWriter printWriter = new PrintWriter(outputStream, true);
printWriter.println(new java.util.Date().toString());
client.close();
}
} catch (IOException exception) {
exception.printStackTrace();
System.err.println(exception);
}
}
}
客户:
public class DateClient {
public static void main(String[] args) throws UnknownHostException,
IOException, InterruptedException {
Socket sock = new Socket("127.0.0.1", 6013);
OutputStream outputStream = sock.getOutputStream();
InputStream inputStream = sock.getInputStream();
System.out.println("" + outputStream + "-" + inputStream);
PrintWriter printWriter = new PrintWriter(outputStream, true);
printWriter.println("Hi Server");
outputStream.close();
System.out.println(sock.isConnected());
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null) { // Exception
System.out.println(line);
}
}
}
在客户端获取下面的套接字关闭异常。
Getting below socket closed exception in Client . Could you please let me know what would be the reason.
Exception in thread "main" java.net.SocketException: Socket closed

推荐答案
java.net.SocketException套接字已关闭
此异常表示您已关闭插座,然后继续尝试使用它。
java.net.SocketException socket is closedThis exception means that you closed the socket, and then continued to try to use it.
os.close();
您在这里关闭了它。关闭套接字的输入或输出流会同时关闭另一个流和套接字。
And you closed it here. Closing either the input or the output stream of a Socket closes the other stream and the Socket.
