smack +openfire 聊天开发（二）连接，注册用户、发送单聊

连接XMPP服务

/**
     * 连接XMPP服务
     * 
     * @return
     * @throws XmppStringprepException
     */
    private AbstractXMPPConnection getXmpptcpConnection() throws XmppStringprepException {
        XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder().setXmppDomain(openfireServer)
                .setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled)
                .setUsernameAndPassword("admin", "admin").setHost(openfireServer).setDebuggerEnabled(false).build();
        AbstractXMPPConnection con = new XMPPTCPConnection(config);
//        SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
//        SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
//        SASLAuthentication.blacklistSASLMechanism("CRAM-MD5");
        xmppConnection = con;
        return con;
    }

注册用户

public void register(String userName,String openid) throws InterruptedException, XmppStringprepException {
	
                
		HashMap<String, Object> map = new HashMap<>();
		map.put("openid", openid);
		List<ChatGroup> list = chatGroupService.selectByMap(map);
		if (list.size() > 0)// 如果已经注册过，不做任何操作
		{
			return;
		}
		AbstractXMPPConnection con = getXmpptcpConnection();
		try {
			// 连接服务
			con.connect();
			if (con.isConnected()) {
				{
					HashMap<String, String> attributes = new HashMap<String, String>();
					attributes.put("name", userName);
					AccountManager.sensitiveOperationOverInsecureConnectionDefault(true);
					Localpart usernameL = Localpart.from(userName);
					AccountManager.getInstance(con).createAccount(usernameL, "123456", attributes);

					
				}
			}

		} catch (SmackException | IOException | XMPPException e) {
			e.printStackTrace();
		} finally {
//			con.disconnect();// 断开连接
		}
	}

单聊发送

/**
 * 单聊发消息
 * 
 * @param receive
 * @param body
 * @throws Exception
 */
@RequestMapping("/sendMsg")
public void sendChatMessage(String name, String receive, String body) throws Exception {

	AbstractXMPPConnection connection = ConnectionMap.get(name);
	if (connection == null) {
		if (name.equals("admin")) {
			connection = getXmpptcpConnection("admin", "admin");
		} else {
			connection = getXmpptcpConnection(name, "123456");
		}
		// 拼凑jid
		connection.connect();
		if (!connection.isAuthenticated()) {
			connection.login();
			ConnectionMap.put(name, connection);
		}
	}
	mChatManager = ChatManager.getInstanceFor(connection);
	EntityBareJid jid = JidCreate.entityBareFrom(receive + "@" + openfireServer);
	Chat chat = mChatManager.chatWith(jid);
	Message message = new Message();
	message.setType(Message.Type.chat);
	// 发送消息格式需要处理
	message.setBody(body);
	chat.send(message);
