openfire自定义发送消息

加入以下类：

这个是xml格式的，解析时可以将xml转成map，参数可自由定义

import org.jivesoftware.smack.packet.PacketExtension;
 
/**
 * 为Message扩展信息
 */
public class ChatInfo implements PacketExtension{
 
    //元素名称小写，便于xml转map时取值
    //聊天信息元素名称
    private static String elementName = "chatinfo";
    //病例id元素名称
    private static String caseIdElement = "caseid";
    //消息类型：1文字2语音3图片4视频5就医建议
    private static String zTypeElement = "ztype";
    //发送人身份：1医生2患者
    private static String identityElement = "identity";
    //长度

消息发送时将自定义的消息带上（示例用的是smack）

public static void SendMsg(String username, String pass, String content, String toUser, String type, String caseId, String identity, String filePath, String realPath
            , String senderId, String sendeeId
            ) throws XMPPException {
        Connection con = login(username, pass);
        Chat mychat = con.getChatManager()
                .createChat(toUser + "@" + "192.168.1.254", // 接收端的JID，JID是要加域的  zsmy-of-test
                new MessageListener() {
                    @Override
                    public void processMessage(Chat chat, Message message) {
                        String messageBody = message.getBody();
                        Constant.MY_LOG.debug("收到信息：" + messageBody + " " + message.getFrom());
                    }
                });
 
        Message msg = new Message();
        ChatInfo chatInfo = new ChatInfo();
        chatInfo.setCaseId(caseId);
        chatInfo.setIdentity(identity);
        chatInfo.setzType(type);
        chatInfo.setSenderid(senderId);
        chatInfo.setSendeeid(sendeeId);
        if ("3".equals(type)) {
            chatInfo.setMsglength("0");
            msg.setBody(filePath);
        } else {
            chatInfo.setMsglength(content.length() + "");
            msg.setBody(content);
            // mychat.sendMessage(content);
        }
        msg.addExtension(chatInfo); // 添加扩展内容
        mychat.sendMessage(msg);
        // con.disconnect(); // 断开连接
    }
