嗨,我是 Java 新手。它给了我很大的压力。我需要与 smack api 和 openfire 服务器聊天。为此,我的java代码如下
import java.util.*;
import java.io.*;
import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;
public class RunJabberSmackAPI implements MessageListener{
XMPPConnection connection;
public void login(String userName, String password) throws XMPPException {
ConnectionConfiguration config = new ConnectionConfiguration("127.0.0.1 ",5222,"localhost");
connection = new XMPPConnection(config);
connection.connect();
connection.login(userName, password);
}
public void sendMessage(String message, String to) throws XMPPException {
Chat chat = connection.getChatManager().createChat(to, this);
chat.sendMessage(message);
}
public void displayBuddyList()
{
Roster roster = connection.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
System.out.println("\n\n" + entries.size() + " buddy(ies):");
for(RosterEntry r:entries) {
System.out.println(r.getUser());
}
}
public void disconnect() {
connection.disconnect();
}
public void processMessage(Chat chat, Message message) {
if(message.getType() == Message.Type.chat)
System.out.println(chat.getParticipant() + " says: " + message.getBody());
}
public static void main(String args[]) throws XMPPException, IOException {
// declare variables
RunJabberSmackAPI c = new RunJabberSmackAPI();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String msg;
// turn on the enhanced debugger
XMPPConnection.DEBUG_ENABLED = true;
// Enter your login information here
c.login("admin", "admin"); // I created this user with openfire.
c.displayBuddyList();
System.out.println("-----");
System.out.println("Who do you want to talk to? - Type contacts full email address:");
String talkTo = br.readLine();
System.out.println("-----");
System.out.println("All messages will be sent to " + talkTo);
System.out.println("Enter your message in the console:");
System.out.println("-----\n");
while( !(msg=br.readLine()).equals("bye")) {
c.sendMessage(msg, talkTo);
}
c.disconnect();
System.exit(0);
}
}
我在我的电脑上运行此代码两次。每个用于单个用户。我通过添加公鸡将这两个用户添加为openfire中的朋友。但是,当他们通过运行上面的 java 代码登录时,他们会在那里发送存在 as available 。但是他们不能将他们的存在发送给彼此可用。相反,他们从好友那里收到两条错误消息。

我不知道我的代码有什么问题。我真的需要尽快解决这个问题。我也在其他论坛发布了这个问题,但找不到任何答案。因此,如果任何人都可以有任何解决方案,那将是一个很大的帮助。谢谢你。
