错误：MySQLSyntaxErrorException - 拒绝用户选择命令

Question

我正在使用 hibernate 和 spring 框架从我的 web 应用程序连接到远程 MySQL 数据库

当我尝试从数据库中获取元素时，由于缺乏权限，它不起作用。

 public Medecin getMedecinByLoginPassword(String login, String password) {
    System.out.println(login);
    System.out.println(password);
    List list;
    list = getSessionFactory().getCurrentSession()
       .createQuery("from Medecin where login= :login and password= :password")
       .setString("login", login).setString("password", password).list();
    return (Medecin) list.get(0);
}

只有 Native sql 可以从远程数据库中获取数据，否则我会收到此错误

错误

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: SELECT command denied to user 'tunisie_tunisie'@'196.203.218.102' for table 'medecin'

这清楚地表明，您尝试使用主机 ip 196.203.218.102 上的用户名 tunisie_tunisie 连接的数据库无权使用此表。检查您是否具有访问此数据库的正确权限。
