I have been using Openfire server 4.6.2, and the REST API plugin was version 1.10.2. I made some code modifications by adding an interface for the server to send messages to users. The main changes include modifying the MessageService with the addition of “Code 1”. The relevant class is SendMsgComponet, where the “Code 2” segment is involved. Due to a vulnerability, I decided to upgrade Openfire to version 4.7.5. However, after upgrading Openfire and uploading the plugin, it seems not to be working, and the error message is as follows. How can I fix this?
code 1
@POST
@Path("/send")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public String sendMessage(MessageEntityToSomeBody messageEntityToSomeBody) {
Message msg = new Message();
Logger Log = LoggerFactory.getLogger(MessageService.class);
Log.debug("body:" + messageEntityToSomeBody.getBody() + " fromJid:" + messageEntityToSomeBody.getFromJid() + " toJid:" + messageEntityToSomeBody.getToJid());
msg.setBody(messageEntityToSomeBody.getBody());
msg.setFrom(messageEntityToSomeBody.getFromJid());//发信人
msg.setTo(messageEntityToSomeBody.getToJid());//接收人
msg.setType(Message.Type.chat);//为聊天信息
msg.setSubject(messageEntityToSomeBody.getSubject());
if (messageEntityToSomeBody.getMsgBodyType() != null && !messageEntityToSomeBody.getMsgBodyType().isEmpty()) {
msg.addChildElement("msgBodyType","").setText(messageEntityToSomeBody.getMsgBodyType());
}
SendMsgComponet sendMsgComponet = new SendMsgComponet();
sendMsgComponet.SendMsg(msg);
return "";
}
