Smack4.1.1 聊天推送

基于openfire_3_10_0、smack_4_1_1 的聊天推送demo.
前提：在最新版本中通过smack类库实现聊天内容的推送方式和旧版本变化有点大。
《注意》
在导入smack本身的jar包之外，还需要以下第三方库的支持,请事先准备下载：
1. commons-logging-1.2.jar
2. httpclient-4.4.jar
3. jxmpp-core-0.4.1.jar
4. jxmpp-util-cache-0.4.1.jar
5. minidns-0.1.1.jar
6. xpp3-1.1.4.jar

如需要自定义扩展聊天内容可参照 MessageExtension类实现

AbstractXMPPConnection conn = null;
try {
Builder builder = XMPPTCPConnectionConfiguration.builder();
builder.setSecurityMode(SecurityMode.disabled);
XMPPTCPConnectionConfiguration config = builder
.setUsernameAndPassword("admin","12345678")
.setServiceName("192.168.1.118").setHost("192.168.1.118")
.setPort(5222).build();

conn = new XMPPTCPConnection(config);

conn.connect();
conn.login();
Message msg = new Message();
msg.setTo("feng123@192.168.1.118");
msg.setBody("admin给 feng123发消息1112=====");
// 自定义扩展message
MessageExtension ext = new MessageExtension();
ext.setProperty("qstId","aac18a578d1c4c1fb88101a43fb92bdc");
ext.setProperty("messageType","0");
msg.addExtension(ext);
conn.sendStanza(msg);



} catch (Exception e) {
e.printStackTrace();
} finally {
if (conn != null) {
try {
conn.disconnect();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
