使用Mapper接口方式整合MyBatis-Spring图书管理系统源代码

//跳转到修改图书信息页面 @RequestMapping("/toUserEdit") public String toUserEdit(Integer user_id, Model model){ //放进model User user = userService.findUserById(user_id); model.addAttribute("user", user); // model.addAttribute("user_id",user_id); //到视图:jsp页面 return "/jsp/user/useredit"; } //修改图书信息 @RequestMapping("/userEdit") public String userEdit(User user, BindingResult bindingResult,Model model){ if(bindingResult.hasErrors()){ err(bindingResult,model); return "/jsp/user/useredit"; }else { userService.updateUser(user); return "redirect:toUserList"; } } //删除 @RequestMapping("/userDelete") public String userDelete(Integer user_id,Model model) { userService.deleteUser(user_id); return "redirect:toUserList"; }
