org.hibernate.hql.internal.ast.QuerySyntaxException：意外令牌：*靠近第1行

我必须登录我的网站

   Login  

在控制器中我有

 @RequestMapping(value="/login",method=RequestMethod.POST) public String loginUser(@RequestParam("email") String email, @RequestParam("password") String password,Model model,HttpSession session){ User persistedUser = userService.getUserByEmail(email); if(persistedUser!=null && persistedUser.getPassword().equals(password)){ session.setAttribute("user", persistedUser); return "home"; }else{ model.addAttribute("error", "Incorrect username or password, Please try again!"); return "login"; } } 

在UserService中我将getUserByEmail（）作为

 public User getUserByEmail(String email) { return (User) em.createQuery("SELECT * FROM User u WHERE u.email = :email").setParameter(email, "Not Found"); } 

当我尝试登录时，我得到了

如何为getUserByEmail（）编写正确的查询，以便我可以摆脱这个exception。

Answer 1

您必须省略SELECT *部分，它是隐式的：

 return (User) em.createQuery("FROM User u WHERE u.email = :email").setParameter(email, "Not Found");
