About the Javaweb Project SSM framework start a Tomcat server and start a socket service at the same time

1. Create a Listener class

Import Javax.servlet.ServletContext;
Import javax.servlet.ServletContextEvent;
Import Javax.servlet.ServletContextListener;

/**
* Boot the socket service with Tomcat
* @author Huajian
*/
public class Socketserviceloader implements servletcontextlistener{
Socket Server Thread
Private Socketthread Socketthread;

@Override
public void contextdestroyed (Servletcontextevent arg0) {
if (Null!=socketthread &&!socketthread.isinterrupted ())
{
Socketthread.closesocketserver ();
Socketthread.interrupt ();
}
}

@Override
public void contextinitialized (Servletcontextevent arg0) {
TODO auto-generated Method Stub
if (Null==socketthread)
{
New Thread class
Socketthread=new socketthread (NULL);
Start thread
Socketthread.start ();
}
}
}

2. Create a production socket thread class:

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

Import Javax.servlet.ServletContext;

/**
* Socket Thread Class
* @author Huajian
*/
public class Socketthread extends thread{
Private ServerSocket serversocket = null;

Public Socketthread (ServerSocket serverscoket) {
try {
if (null = = ServerSocket) {
This.serversocket = new ServerSocket (4700);
SYSTEM.OUT.PRINTLN ("socket start");
}
} catch (Exception e) {
System.out.println ("Socketthread Creating socket Service error");
E.printstacktrace ();
}

}

public void Run () {
while (!this.isinterrupted ()) {
try {
Socket socket = serversocket.accept ();

if (null! = Socket &&!socket.isclosed ()) {
Processing the accepted data
New Socketoperate (socket). Start ();
}
Socket.setsotimeout (30000);

}catch (Exception e) {
E.printstacktrace ();
}
}
}

public void Closesocketserver () {
try {
if (Null!=serversocket &&!serversocket.isclosed ())
{
Serversocket.close ();
}
} catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
}

3. Create a class that handles client-sent messages:

Import Java.io.BufferedReader;
Import java.io.IOException;
Import Java.io.InputStream;
Import Java.io.InputStreamReader;
Import Java.io.PrintWriter;
Import Java.net.Socket;

Import Javax.servlet.ServletContext;

/**
* Multithreading processing the data received by the socket
* @author Huajian
*
*/
public class Socketoperate extends thread{
private socket socket;

Public socketoperate (socket socket) {
This.socket=socket;
}
@SuppressWarnings ("unused")
public void Run ()
{
try{

InputStream in= Socket.getinputstream ();

PrintWriter out=new PrintWriter (Socket.getoutputstream ());

BufferedReader wt = new BufferedReader (new InputStreamReader (system.in));

while (true) {
Read the information sent by the client
String strxml = "";
byte[] temp = new byte[1024];
int length = 0;
while (length = in.read (temp))! =-1) {
Strxml + = new String (temp,0,length);
}
if ("End". Equals (Strxml)) {
System.out.println ("Ready to close socket");
Break
}
if ("". Equals (Strxml))
Continue

SYSTEM.OUT.PRINTLN ("Client sent to:" +strxml.tostring ());

Methodhandler MH = new Methodhandler (Readxml.readxml (strxml.tostring ()));
String resultxml = Mh.getresultxml ();
System.out.println ("Return:" +resultxml.tostring ());

if (! "". Equals (Resultxml)) {
Out.print (Resultxml);
Out.flush ();
Out.close ();
// }


}
Socket.close ();
SYSTEM.OUT.PRINTLN ("Socket stop ...");

}catch (IOException ex) {

}finally{

}
}
}

4. Configuring monitoring in Web. config

<listener>
<listener-class>com.novolion.wateriot.server.SocketServiceLoader</listener-class>
</listener>
