Smack Client Configuration for Instant Messaging

Prior to learning through Openfire+spark+smack mode to complete our instant Messenger software, the last time we have completed the installation and configuration of OpenFire, this time we continue to complete our client section.

1. First we use Baidu smack to download the jar package we need, import the downloaded jar package into our project, create a tool class Xmpptool:

Package Com.xmpp.client.util;import Org.jivesoftware.smack.connectionconfiguration;import Org.jivesoftware.smack.xmppconnection;import Org.jivesoftware.smack.xmppexception;import Org.json.JSONArray;    public class Xmpptool {private static xmppconnection con = null;             private static void OpenConnection (string url, string pcname) {try {//URL, port, can also be set to connect server name, address, port, user. Connectionconfiguration connconfig = new Connectionconfiguration ("192.168.2.113", 5222, "J            Erehedu ");            con = new Xmppconnection (connconfig);        Con.connect ();        } catch (Xmppexception Xe) {xe.printstacktrace (); }} private static void Openoffconnection (string url, string pcname) {try {Connectionconfigurati            On connconfig = new Connectionconfiguration (URL, 5222, pcname);            Connconfig.setsendpresence (FALSE);            con = new Xmppconnection (connconfig); Con.connect ();        } catch (Xmppexception Xe) {xe.printstacktrace ();            }} public static xmppconnection getoffconnection (string url, string pcname) {if (con = = null) {        Openoffconnection (URL, pcname);    } return con; public static xmppconnection getconnection (string url, string pcname) {if (con = = null) {Openconn        Ection (URL, pcname);    } return con;        } public static void CloseConnection () {con.disconnect ();    con = null; }}

Tool Class Xmpptool

Mainly through the connectionconfiguration to connect to the server, passing in three parameters (address, port, user name)

There are a lot of classes that come with our own, and we just have to implement it.
