如何防止使用JPA和Hibernate进行SQL注入?

问题描述：

我正在使用休眠模式开发应用程序.当我尝试创建登录页面时，出现Sql注入问题. 我有以下代码:

I am developing an application using hibernate. When I try to create a Login page, The problem of Sql Injection arises. I have the following code:

@Component
@Transactional(propagation = Propagation.SUPPORTS)
public class LoginInfoDAOImpl implements LoginInfoDAO{

@Autowired
private SessionFactory sessionFactory;      
@Override
public LoginInfo getLoginInfo(String userName,String password){
    List<LoginInfo> loginList = sessionFactory.getCurrentSession().createQuery("from LoginInfo where userName='"+userName+"' and password='"+password+"'").list();
    if(loginList!=null )
        return loginList.get(0);
    else return null;   
          }
      }

在这种情况下如何防止Sql注入?loginInfo表的创建表语法如下:

How will i prevent Sql Injection in this scenario ?The create table syntax of loginInfo table is as follows:

create table login_info
  (user_name varchar(16) not null primary key,
  pass_word varchar(16) not null);

答

Query q = sessionFactory.getCurrentSession().createQuery("from LoginInfo where userName = :name");
q.setParameter("name", userName);
List<LoginInfo> loginList = q.list();
