org.hibernate.hql.internal.ast.QuerySyntaxException：意外的標記：*近線1

我有登陸我的網站org.hibernate.hql.internal.ast.QuerySyntaxException：意外的標記：*近線1

<form method="post" action="login"> 
    <input type="text" placeholder="Email" name="email"> 
    <input type="password" placeholder="Password" name="password"> 
    <button type="submit">Login</button> 
</form>

在控制器我有

@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"; 
     } 

    }

和UserService我getUserByEmail（）作爲

當我嘗試登錄我得到

如何爲getUserByEmail（）編寫正確的查詢，以便我可以擺脫此異常。

你必須忽略SELECT *部分，它是隱：

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

好擺脫了這一點，但遇到其他的是當我輸入電子郵件地址和密碼，我得到'java.lang.IllegalArgumentException異常：參數與名稱[[email protected]]不存在'，爲什麼會發生 –

我想這是不正確的：'.setParameter（email，「Not Found」）;'。嘗試使用'.setParameter（「email」，email）;'。第一個參數是查詢中參數的名稱;第二個參數是該參數的值。 – BackSlash

好，但很抱歉說有其他異常'java.lang.ClassCastException：$ Proxy41不能轉換爲com.rhcloud.giveme.entity.User'在'return（User）em.createQuery（「FROM User u WHERE u.email =：email「）。setParameter（」email「，email）;'。 –
