How to block your own notifications

I am trying to learn how to build a forum from an available source. However the problem I have is the function to reply to comments and answer questions. When I reply to my question or comment, notify me that "vkhacbao answered vkhacbao's question" (vkhacbao is the account I log into). How can I block or set the condition so that when I comment, it's not sent to myself. Please help me, I tried everything for 3 days but with no success. Thanks very much
Code:

CommentController.java

@Controller
public class CommentController {
@Resource
private UserMapper userMapper;
@Resource
private CommentMapper commentMapper;
@Resource
private QuestionMapper questionMapper;
@Resource
private NotificationMapper notificationMapper;
@ResponseBody
@RequestMapping(value = "/comment",method = RequestMethod.POST)
public Object post(@RequestBody CommentCreateDto commentCreateDto,
HttpServletRequest request){
//把User写进session
Cookie[] cookies = request.getCookies();
if (cookies == null) {
return "login";
}
User user = null;
for (Cookie cookie : cookies) {
if (cookie.getName().equals("token")) {
String token = cookie.getValue();
user = userMapper.findBytoken(token);
if (user != null) {
request.getSession().setAttribute("user", user);
//获取未读的消息数量
int unreadnum=notificationMapper.getunreadcount(user.getId());
request.getSession().setAttribute("unreadnum",unreadnum);
}
break;
}
}
//把评论插入数据库
Comment comment=new Comment();
comment.setParent_id(commentCreateDto.getParent_id());
comment.setContent(commentCreateDto.getContent());
comment.setType(commentCreateDto.getType());
comment.setCreatetime(System.currentTimeMillis());
comment.setCommentor(user.getId());
commentMapper.insert(comment);
if (commentCreateDto.getType()==2){
//把回复评论的通知插入数据库
Notification notification=new Notification();
notification.setNotifier(comment.getCommentor());
Comment comment2=commentMapper.getparentbyid(commentCreateDto.getParent_id());
notification.setReceiver(comment2.getCommentor());
notification.setOuterid(commentCreateDto.getParent_id());
notification.setType(notificationEnum.NOTIFICATION_COMMENT.getType());
notification.setCreatetime(System.currentTimeMillis());
notification.setStatus(NotificationStatusEnum.UNREAD.getStatus());
notificationMapper.inserts(notification);
//增加评论数
commentMapper.updatecommentcount(commentCreateDto.getParent_id());
}
else {
//把回复问题的通知插入数据库
Question question=questionMapper.getbyId(commentCreateDto.getParent_id());
Notification notification=new Notification();
notification.setNotifier(user.getId());
notification.setReceiver(question.getCreateid());
notification.setOuterid(commentCreateDto.getParent_id());
notification.setType(notificationEnum.NOTIFICATION_QUESTION.getType());
notification.setCreatetime(System.currentTimeMillis());
notification.setStatus(NotificationStatusEnum.UNREAD.getStatus());
notificationMapper.inserts(notification);
//增加问题回复量
questionMapper.updatecomment(commentCreateDto.getParent_id());
}
ResultDto resultDto=new ResultDto();
return resultDto.success();
}
@ResponseBody
@RequestMapping(value = "/comment/{id}",method = RequestMethod.GET)
public ResultDto<List<CommentDto>> comments(@PathVariable(name = "id") int id,
HttpServletRequest request){
//查找type=2，即是回复评论的评论
List<Comment> comments = commentMapper.getCommentByid(id,2);
List<CommentDto> commentDto=new ArrayList<>();
//找到User
Cookie[] cookies = request.getCookies();
User user = null;
for (Cookie cookie : cookies) {
if (cookie.getName().equals("token")) {
String token = cookie.getValue();
user = userMapper.findBytoken(token);
break;
}
}
//把二级评论和对应的User写进每个CommentDto集合中
for (Comment comment:comments){
CommentDto dto=new CommentDto();
BeanUtils.copyProperties(comment,dto);
dto.setUser(user);
commentDto.add(dto);
}
ResultDto resultDto=new ResultDto();
//返回数据给前端
return resultDto.success(commentDto);
}
}

NotificationController.java

@Controller
public class NotificationController {
@Resource
private NotificationMapper notificationMapper;
@Resource
private CommentMapper commentMapper;
@GetMapping("/notification/{action}")
public String notification(@PathVariable("action")int id,
HttpServletRequest request){
//将通知设置为已读
notificationMapper.updatestatus(id);
//获取type，检验是回复评论还是回复问题
int type=notificationMapper.gettypebyid(id);
int outerid=notificationMapper.getouteridbyid(id);
int questionid;
if(type== notificationEnum.NOTIFICATION_QUESTION.getType()){
questionid=outerid;
}else {
questionid=commentMapper.getparentidbyid(id);
}
return "redirect:/question/"+questionid;
}
}

QuestionController.java

@Controller
public class QuestionController {
@Resource
private QuestionService questionService;
@Resource
private UserMapper userMapper;
@Resource
private CommentService commentService;
@Resource
private NotificationMapper notificationMapper;
@GetMapping("/question/{id}")
public String question(@PathVariable(name = "id")int id,
Model model,
HttpServletRequest request){
//查找cookies，观察是否有token存在
Cookie[] cookies = request.getCookies();
if (cookies == null) {
return "login";
}
User user = null;
for (Cookie cookie : cookies) {
if (cookie.getName().equals("token")) {
String token = cookie.getValue();
user = userMapper.findBytoken(token);
if (user != null) {
request.getSession().setAttribute("user", user);
//获取未读的消息数量
int unreadnum=notificationMapper.getunreadcount(user.getId());
request.getSession().setAttribute("unreadnum",unreadnum);
}
break;
}
}
Questiondto questiondto=questionService.getbyid(id);
//增加阅读数
questionService.increaseview(id);
model.addAttribute("questionDto",questiondto);
//展示回复数据
List<CommentDto> comments=commentService.getByid(id);
model.addAttribute("comments",comments);
//相关问题
String[] tags=questiondto.getTag().split(",");
StringBuilder msg=new StringBuilder();
for (String tag:tags){
msg.append(tag);
msg.append("|");
}
String result=msg.substring(0,msg.length()-1);
List<Question> relativequestion =questionService.getbytag(id,result);
model.addAttribute("relativequestion",relativequestion);
return "question";
}
}

Assuming the owners of the original message and the commenter are in the CommentController class, it would be this section

if (commentCreateDto.getType()==2){
    Comment comment2=commentMapper.getparentbyid(commentCreateDto.getParent_id());
       
    if ( !comment2.getCommentor().equals(comment.getCommentor()) ) {
        Notification notification=new Notification();
        notification.setNotifier(comment.getCommentor());
        notification.setReceiver(comment2.getCommentor());
        notification.setOuterid(commentCreateDto.getParent_id());
        notification.setType(notificationEnum.NOTIFICATION_COMMENT.getType());
        notification.setCreatetime(System.currentTimeMillis());
        notification.setStatus(NotificationStatusEnum.UNREAD.getStatus());
        notificationMapper.inserts(notification);
        commentMapper.updatecommentcount(commentCreateDto.getParent_id());
    }
}

Unfortunately, if that doesn't work for you, you'll need to learn more about the language and the code to determine where to make the change.
