I'm doing an application to show data from some gps on the web, but I'm not clear about the topic of capturing the frames
I would like to make a socket in java but I'm not sure how to do it, so that it runs in the background and I capture the data of the gps.
I would do it this way:
package ejemplo.com;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.ServerSocket;
import java.net.Socket;
public class ServidorEscucha {
public ServidorEscucha() throws Exception{
InetAddress hostIp;
hostIp = InetAddress.getByName("127.0.0.1"); // O la que necesites
ServerSocket escuchar = new ServerSocket(1234, 1000, hostIp); // Puerto 1234 o el que requieras abrir
try {
while (true) {
new AtenderCliente(escuchar.accept()).start();
}
} finally {
escuchar.close();
}
}
private static class AtenderCliente extends Thread {
private Socket socket;
public AtenderCliente(Socket socket) {
this.socket = socket;
}
public void run() {
try {
// Preparamos el buffer para leer la data de los GPS
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
// Leeemos linea a linea lo que envíe el GPS
while (true) {
String TramaEntrante = in.readLine();
if (TramaEntrante == null) {
break;
}
// Procesar la trama entrada como se requiera
// *** PARSEAR / ALMACENAR EN DB ***********
}
} catch (IOException e) {
System.out.println("Error en cliente: " + e.getMessage());
} finally {
try {
socket.close();
} catch (IOException e) {
System.out.println("No se pudo cerrar el puerto: " + e.getMessage());
}
System.out.println("Conexión con cliente cerrada.");
}
}
}
}
