我认为在 for 循环中为每个通知创建一个新的 arrylist 对象并添加通知，以便它提供唯一的最后一个通知

你可以试试这个

公共 ModelAndView getNotifications(int id){

    System.out.println("Method ios called");
    Session session = usermanagementSessionFactory.openSession();
    ArrayList li =null;
    System.out.println("after Getting Session");
    int  id1  = id;
    System.out.println(id1);
    Query query=(Query) session.getNamedQuery("getNotification");
    query.setInteger("userId",id1);

    List<Message> list1= query.list();
    ArryList li = new ArrayList();
    ModelAndView mv = new ModelAndView("notifications");
    for(Message userData:list1)
    {

        String notifications=userData.getNotification();
        boolean isNew=(boolean) userData.isNew();


        li.add(notifications);


        //li.add(mname1);
