Multithreaded +socket for Java

Client:

Package Com.wulala;

Import Java.io.FileOutputStream;
Import java.io.IOException;
Import Java.io.InputStream;
Import Java.io.OutputStream;
Import Java.net.Socket;
Import java.net.UnknownHostException;

public class Client {
public static void Main (string[] args) {
Client client = new Client ();
Client.run ();

}

public void Run () {
Socket client;
try {
Client = new Socket ("127.0.0.1", 9999);
2. Open the flow information for the socket and prepare the following actions
OutputStream OS = Client.getoutputstream ();
3. Write a message
Os.write (("xxxxasdf12233"). GetBytes ());

}
} catch (Unknownhostexception e) {
TODO auto-generated Catch block
E.printstacktrace ();
} catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
}

Parentheses may not be complete and unimportant.

The client has nothing to say, is to open a target server an IP, followed the port, and then outputsteam some things into, analog back STM32 through the GPRS connection server through the serial port through the transmission of data.

Server-side:

Package Com.wulala;

Import java.io.IOException;
Import Java.io.InputStream;
Import Java.net.ServerSocket;
Import Java.net.Socket;

public class Multisocketserver {
public static void Main (String args[]) {
Multisocketserver multisocketserver = new Multisocketserver ();
try {
Multisocketserver.startserver ();
} catch (Exception ex) {

System.out.println (Ex.getmessage ());
}

}

public void StartServer () throws IOException {
ServerSocket SS = null;
try {
SS = new ServerSocket (9999);
} catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
while (true) {
1. Open the Socket connection
Waiting for a client request
Final Socket server = Ss.accept ();

SYSTEM.OUT.PRINTLN ("Service-----------request starts start");

2. Open the flow information for the socket and prepare the following actions
Final InputStream is = Server.getinputstream ();
byte b[] = new byte[1024];

int readcount = Is.read (b);

String str = new string (b);

str = Str.trim ();

Final String serverfilename = str;

if (Readcount > 0) {
New Thread () {

@Override
public void Run () {

SYSTEM.OUT.PRINTLN ("Thread" + thread.currentthread (). GetName () + "start");
3. Stream information for read and write operations
SYSTEM.OUT.PRINTLN ("The message sent by the client is:" + serverfilename);

Executedml edml = new Executedml ();
try {
Edml.initparam ("Dbconfig.properties");
} catch (Exception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
int insertresult = 0;

String DeviceID = "";
int activate = 0;
if (Serverfilename.length () > 9) {
DeviceID = serverfilename.substring (0, 8);
activate = Integer.valueof (serverfilename.substring (8));
}
try {
Insertresult = Edml.insertwxdata ("AAAA", 113);
Insertresult = Edml.insertwxdata (DeviceID, activate);
SYSTEM.OUT.PRINTLN ("Total" +insertresult+ "result been changed");
} catch (Exception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
try {
Is.close ();
Server.close ();
} catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}

Return
}
}.start ();
}

SYSTEM.OUT.PRINTLN ("Service-----------request end over");
}
}
}

To put it simply, a thread is used when the data comes up, and in this project, a string is usually sent over, and the first 8 bits of the string are the device name, followed by the number of activations. or something.

In the future to receive data validation, analysis of what, the late reconstruction bar.
