IM读取联系人

【IT168技术文档】

  最近在做IM读取联系人的工作，主要包括MSN和Gtalk，研究了以下smack和jml的文档，发现还是比较容易的，虽然代码很少，但是却颇费了一般周折
  代码如下：

package com.ruby.service.contacts;
import java.util.ArrayList;
import java.util.List;
import net.sf.jml.MsnContact;
import net.sf.jml.MsnList;
import net.sf.jml.MsnMessenger;
import net.sf.jml.MsnUserStatus;
import net.sf.jml.event.MsnContactListAdapter;
import net.sf.jml.impl.MsnMessengerFactory;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
public class IMRosterService {
private String user;
private String password;
private String type;
public IMRosterService(String user, String password, String type) {
this.user = user;
this.password = password;
this.type = type;
}
public List<ContactFriend> getContactList() {
if(type.equals("msn"))
return getMsnRoster();
return getGtalkRoster();
}
private List<ContactFriend> getMsnRoster() {
MsnMessenger messenger = null;
final List<ContactFriend> list = new ArrayList<ContactFriend>();
try {
messenger = MsnMessengerFactory.createMsnMessenger(user, password);
messenger.getOwner().setInitStatus(MsnUserStatus.BUSY);
messenger.addContactListListener(new MsnContactListAdapter() {
public void contactListInitCompleted(MsnMessenger messenger) {
MsnContact[] contacts = messenger.getContactList().getContactsInList(MsnList.AL);
for (int i = 0; i != contacts.length; i++) {
String email = contacts[i].getEmail().getEmailAddress();
String name  = contacts[i].getDisplayName();
list.add(new ContactFriend(email, name));
}
}
});
messenger.login();
// must wait until result
Thread.sleep(5000);
} catch (Exception e) {
e.printStackTrace();
} finally {
messenger.logout();
}
return list;
}
private List<ContactFriend> getGtalkRoster() {
List<ContactFriend> list = new ArrayList<ContactFriend>();
ConnectionConfiguration connectionConfig = new ConnectionConfiguration("talk.google.com", 5222, "gmail.com");
XMPPConnection connection = new XMPPConnection(connectionConfig);
try {
connection.connect();
connection.login(user, password);
Roster roster = connection.getRoster();
if(roster != null) {
for (RosterEntry entry : roster.getEntries()) {
String email = entry.getUser();
String name = entry.getName();
if(name==null) {
name = email;
}
ContactFriend friend = new ContactFriend(email, name);
list.add(friend);
}
}
} catch (XMPPException e) {
e.printStackTrace();
} finally {
if(connection.isConnected())
connection.disconnect();
}
return list;
}
}
