刚刚开始搭建架构.以前代码没有带.求BaseDao代码以做参考!

今天下午没人回.我自己来回复

可以考虑自己写哈，那个什么BaseDao也是别人写的，只是封装了一些常用的方法而已。
如果实在需要可以考虑用Hibernate自带的HibernateTemplate类或者HibernateSupportDao类，不知道类名有没有拼错！有段时间没用Hibernate了。

哎。。弄出来了

package com.cls.dao;

public interface BaseDao<T,S> {
    public void save(T entity);

    public void deleteById(S PK);

    public void delete(T entity);
   
    public void update(T entity);
   
    public T findById(S PK);
}

        this.sessionFactory = (SessionFactory) apc.getBean("sessionFactory");
    }

    public void delete(T entity) {
        Session session = sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        session.delete(entity);
        session.close();

    }

    public void deleteById(S PK) {
        Session session = sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        T t = (T) session.get(this.entityClass, PK);
        session.delete(t);
        ();
    }

    public T findById(S PK) {
        Session session = sessionFactory.openSession();
        Transaction tx = session.beginTransaction();

你这个BaseDao功能挺少的。。。
