我正在开发一个spring-mvc项目,该项目使用JSP文件添加注释。现在,所有CRUD操作都在项目中工作。唯一的问题是在数据库中看到更新的信息,我每次都要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,我觉得没有用。我发布我的控制器代码和JSP代码。任何想法,我需要点击刷新。
P.S:删除功能不需要刷新,是的,我尝试将重定向用于其他功能。
COntroller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));
}

答案 0 :(得分:1)
所以我最终通过在/ note / add函数的末尾调用return“redirect:/ note / listing”来解决它。

要完全清楚这个答案,只需创建:
ModelAndView
控制器,在控制器的末尾,请添加:
ModelAndView mv = new ModelAndView("redirect:/note/listing");
return mv;
