Question

@SuppressWarnings("unchecked")
    @Override
    public StudentCredential getStudentDetailsByUnameAndPassword(String uname,String password){
        Session session;
        DetachedCriteria detachedCriteria =  DetachedCriteria.forClass(StudentCredential.class);
        detachedCriteria.add(Restrictions.eq("uname", uname));
        detachedCriteria.add(Restrictions.eq("password", password));
        List<StudentCredential> findByCriteria = (List<StudentCredential>)Hibernate template .findByCriteria(detachedCriteria);
        if(findByCriteria !=null && findByCriteria.size()>0)
        return findByCriteria.get(0);
        else
            return null;
    }

我有此代码，并想使用HIbernateTemplate的findByCriteria对数据进行评估现在，我该如何使用会话条件查询或任何其他方法代替Hibernate Template来验证电子邮件和密码此代码有助于保存验证数据库中的电子邮件和密码。

package com.infotech.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.criterion.DetachedCriteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;

import com.infotech.dao.StudentCredentialDao;
import com.infotech.model.Student;
import com.infotech.model.StudentCredential;

@Repository("StudentCredentialDAO")
public class StudentCredentialDaoImpl implements StudentCredentialDao {

    @Autowired
    private SessionFactory sessionFactory;


    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @Override
    public boolean saveStudentCred(StudentCredential stuCred) {
        Session session = this.sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        session.save(stuCred);
        tx.commit();
        session.close();
         return true;
    }

现在保存代码后使用Hibernate模板，但这对我不起作用，我可以做什么来验证代码

@SuppressWarnings("unchecked")
        @Override
        public StudentCredential getStudentDetailsByUnameAndPassword(String uname,String password){
            DetachedCriteria detachedCriteria =  DetachedCriteria.forClass(StudentCredential.class);
            detachedCriteria.add(Restrictions.eq("uname", uname));
            detachedCriteria.add(Restrictions.eq("password", password));
            List<StudentCredential> findByCriteria = (List<StudentCredential>)session.getIdentifier(detachedCriteria);
            if(findByCriteria !=null && Hibernate template .size()>0)
            return findByCriteria.get(0);
            else
                return null;
        }
    }

这是我的DAO文件的完整代码，我不想使用Hibernate Template，因为它与Oracle数据库有关。因此，使用会话。

在Spring Hibernate中使用Session方法使用findByCriteria
