即时通讯软件的离线消息获取

[jayqean]

做一个IM,采用的smack.jar/smackx.jar两个jar包
连接服务器端成功后,无法获取离线消息

OfflineMessageManager offlineManager = new OfflineMessageManager(conn); Iterator<org.jivesoftware.smack.packet.Message> it = offlineManager.getMessages(); 
while(it.hasNext()){ 
org.jivesoftware.smack.packet.Message message = it.next(); System.out.println("收到离线消息, Received from 【" + message.getFrom() + "】 message: " + message.getBody()); 
}

首先已经确定服务器端能在客户端上线后发送了离线消息.
有做过的童鞋,可以指点下麽

offlineManager.getMessageCount() 打印出来是0
想用gmail的邮箱测试,奈何公司的网络很差
有哪位好心人帮我测试下就好,用两个gmail邮箱 在对方离线的时候发送条消息 在用下面的代码登录离线的那个帐号,测试有没有收到

import java.util.Iterator;

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Presence;
import org.jivesoftware.smackx.OfflineMessageManager;

public class Test {
    
    public static XMPPConnection getConn() {
        ConnectionConfiguration conf = new ConnectionConfiguration("gmail.com",
                5222);
        conf.setSASLAuthenticationEnabled(false);// gtalk不支持SASL验证，设置为false
        conf.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
        conf.setCompressionEnabled(false);
        XMPPConnection conn = new XMPPConnection(conf);
        return conn;
    }
    
    public static void main(String[] args) {
        XMPPConnection conn = getConn();
        try {
            conn.connect();
            conn.login("username", "password");
            Presence presence = new Presence(Presence.Type.available);
            conn.sendPacket(presence);
            OfflineMessageManager offlineManager = new OfflineMessageManager(conn);
            System.out.println(offlineManager.getMessageCount());
            Iterator<org.jivesoftware.smack.packet.Message> it = offlineManager.getMessages();
            while(it.hasNext()){
                org.jivesoftware.smack.packet.Message message = it.next();
                System.out.println("收到离线消息, Received from 【" + message.getFrom() + "】 message: " + message.getBody());
            }
        } catch (XMPPException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }
}

相关jar包可以从http://www.igniterealtime.org/downloads/index.jsp上获取

解决了最好贴个解决方案 以后如果别人有同样问题就搜索的到答案了~

连接gmail邮箱,
更正下

public static XMPPConnection getConn() {
        ConnectionConfiguration conf = new ConnectionConfiguration("gstalk.guoshi.com",
                5222);
        XMPPConnection conn = new XMPPConnection(conf);
        return conn;
    }

另外离线消息的获取,是服务器在你客户端上线后主动发送过来的,你可以想监听正常情况下聊天消息一样,监听得到离线消息
如果发现你写的测试代码没有获取得到,将主线程sleep段时间吧

我使用OfflineMessageManager这个类没有获取成功,Thread.sleep(10000);也没收到
