Question

@GetMapping
    public List<menu> findAll() {
        return userService.list();
    }
public class UserService extends ServiceImpl<UserMapper, menu> {
    public boolean savemenu(menu menu) {
//        if(menu.getDishID() == null){
//            save = (menu);//mybatis-plus提供的方法，表示插入数据
//        }else{
//            return updateBatchById(menu);
//        }
        return saveOrUpdate(menu);
    }
