Java 冬眠+；春元'；不要保存记录

我试图在数据库中添加记录，但没有保存任何内容。我想找到一些解决办法，但什么都没用。当我试图从数据库中删除用户时，它不起作用。谁能告诉我怎么了

@Transactional
public void addUser(User user) {
    userDao.addUser(user);
}   @Transactional
public List getAllUsers() {
    return userDao.getAllUsers();
}
@Autowired 
private UserDao userDao;

控制器

@RequestMapping(value = "/Users")
public String goUsers(Map <String,Object> map)
{
    User user= new User();
    map.put("user",user);
    map.put("AllUsers",UserS.getAllUsers());
    return "Users";
}

@RequestMapping(value = "/SuppUser",method=RequestMethod.POST)
public String goUsers(@ModelAttribute User user,BindingResult result,@RequestParam String action,Map<String,Object> map) 
{
    User userResult = new User();
    switch(action.toLowerCase()){
    case "Ajouter":
        UserS.addUser(user);
        userResult= user;
        break;
    case "Rechercher":
        User userSearch = UserS.serachUserByLogin(user.getIdUser()) ;
        userResult= userSearch != null ? userSearch : new User();
        break;
    case "Supprimer":
        UserS.deleteUser(user.getIdUser());
        userResult= user;
        break;
    }
    map.put("user", userResult);
    map.put("AllUsers", UserS.getAllUsers());
    return "Users"; 
}
