我認爲在for循環中爲每個通知創建一個新的arrylist對象並添加通知所以它給出了唯一的最後通知

你可以試試這個

公衆的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); 

    if(isNew) 
    { 

     mv.addObject("loginsuccess" ,li); 

    }else 
    { 
     mv.addObject("loginsuccess" ,"There is no New Notifications"); 

    } 


} 

    return mv; 



}
