我有一个连接三个表的hib原生sql查询，我正尝试从结果中检索3列

public void doTestQuery() {

try (Session session = HibernateUtilities.getSessionFactory().openSession()) {
    transaction = session.beginTransaction();

    String sql = "SELECT\r\n"
            + " users.username, \r\n"
            + " user_roles.role_name, \r\n"
            + " address.address\r\n"
            + "FROM\r\n"
            + " address\r\n"
            + " INNER JOIN\r\n"
            + " users\r\n"
            + " ON \r\n"
            + "     address.iduser = users.iduser\r\n"
            + " INNER JOIN\r\n"
            + " user_roles\r\n"
            + " ON \r\n"
            + " users.iduser = user_roles.iduser";
    NativeQuery query = session.createNativeQuery(sql);

    List<Object[]> results = query.list();
    
    for (Object[] arr : results) {

System.out.println(arr[0].toString() +" "+ arr[1].toString() +" "+ arr[2].toString());
    }
    
    transaction.commit();

}

如果我用下面的代码替换System.out.println，它会给我一个错误。有没有办法从这类休眠查询中转换对象？

Users user = (Users) arr[0];
            UserRoles userRole = (UserRoles) arr[1];
            Address _address = (Address) arr[2];    
            System.out.println(user.getUsername() + userRole.getRolename() + _address.getAddress());
