<div class="col-12 col-sm-6">
                                        <div class="form-group">
                                            <label>识别码(6位数)label>

controller页面内容：

@RequestMapping("/StudentsInsert")
    public Object StudentsInsert(PostsAdm postsAdm,Model model){
        int number=postsAdmService.PostsAdmCount();
        postsAdm.setAdmId(AdmId.Randomstr(6)+(number+1));
        postsAdm.setAdmPassword(DigestUtils.md5Hex(postsAdm.getAdmPassword()));
        postsAdm.setAdmIdentificationCode(DigestUtils.md5Hex(postsAdm.getAdmIdentificationCode()));
        postsAdm.setAdmSecondaryPassword(DigestUtils.md5Hex(postsAdm.getAdmSecondaryPassword()));
        System.out.println(postsAdm);
        int num=postsAdmService.PostsAdmInsert(postsAdm);
        if (num>0){
            model.addAttribute("msg",1);
            return "add_student";
        }else {
            model.addAttribute("msg",0);
            return "add_student";
        }
    }

在前台引入了thymleaf的依赖包吧？后台没有报错吧
