Hibernate 带参数查询的两种方式

1、使用？通配符

public User validate(String userName, String password) {
        String hql = "from User u where u.userName = ? and u.password = ?";
        User user = null;
         List<User> list = ht.find(hql, new Object[]{userName, password});
        if (list.size()!=0){
            user = list.get(0);
        }
        return user;
    }

2、使用键值对应

public User validate(String userName, String password) {
        String hql = "from User where userName =:userName and password =:password";
        User user = null;
        Object[] values = {userName, password};
        String[] paramNames = {"userName", "password"};
        List<User> list = ht.findByNamedParam(hql, paramNames, values);
        if (list.size()!=0){
            user = list.get(0);
        }
        return user;
    }
