Spring-MVC模型只在页面刷新后更新

Question

我正在使用JSP文件添加注释的spring-mvc项目。目前，所有CRUD操作都在该项目中运行。唯一的问题是要查看数据库中的更新信息，我必须每次都点击刷新浏览器按钮。我检查了flashattributes，但由于我没有重定向，只是返回对象，所以我觉得没有用。我将我的控制器代码和JSP代码一起发布。任何想法，为什么我需要刷新。

P.S：刷新不是必要的删除功能，是的，我尝试使用其他功能已经重定向。

控制器代码：

@RequestMapping(value= "/note/add") 
    public String addNote(@ModelAttribute("notices") Notes p,Model model) { 
     Person person = personService.getCurrentlyAuthenticatedUser(); 
     model.addAttribute("notices", new Notes()); 
     model.addAttribute("listNotes",this.notesService.listNotes()); 
     model.addAttribute("listNotes", this.notesService.listNotePerson(person)); 
     model.addAttribute("section1",this.notesService.listNotesBySectionId(1,person)); 
     model.addAttribute("section2",this.notesService.listNotesBySectionId(2,person)); 
     model.addAttribute("section3",this.notesService.listNotesBySectionId(3,person)); 
} 
@RequestMapping("/editnote/{id}") 
    public String editNote(@PathVariable("id") Integer id, Model model){ 
     Person person = personService.getCurrentlyAuthenticatedUser(); 
     model.addAttribute("notices", this.notesService.getNoteById(id)); 
     model.addAttribute("section1",this.notesService.listNotesBySectionId(1,person)); 
     model.addAttribute("section2",this.notesService.listNotesBySectionId(2,person)); 
     model.addAttribute("section3",this.notesService.listNotesBySectionId(3,person)); 
} 
@RequestMapping(value = "/note/listing", method=RequestMethod.GET) 
    public String listNotices(Model model) { 

     Person person = personService.getCurrentlyAuthenticatedUser(); 
     model.addAttribute("notices",new Notes()); 
     model.addAttribute("listNotes", this.notesService.listNotePerson(person)); 
     model.addAttribute("section1",this.notesService.listNotesBySectionId(1,person)); 
     model.addAttribute("section2",this.notesService.listNotesBySectionId(2,person)); 
     model.addAttribute("section3",this.notesService.listNotesBySectionId(3,person)); 
} 

JSP代码：

Answer 1

所以我能够通过调用回终于解决它 “重定向：/笔记/列表”，在结束/ note/add功能。

Answer 2

要对这个答案完全清楚，只需创建：

ModelAndView控制器，并在控制器结束后，请加：

ModelAndView mv = new ModelAndView("redirect:/note/listing"); 
return mv;
