dao层BaseDaoImpl

package com.minde.dao;import java.io.Serializable;import java.util.List;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;public class BaseDaoImpl implements IBaseDao {private SessionFactory sessionFactory;
//设置获取注入的sessionFactory
 public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}//列表@Overridepublic List findAll(String hql) {Session session = this.sessionFactory.openSession();Query q = session.createQuery(hql);List list = q.list();session.close();return list;}@Overridepublic void save(Object obj) {Session session = this.sessionFactory.openSession();session.beginTransaction();session.save(obj);session.getTransaction().commit();session.close();}@Overridepublic void update(Object obj) {Session session = this.sessionFactory.openSession();session.beginTransaction();session.merge(obj);session.getTransaction().commit();session.close();}@Overridepublic Object findObjectById(Class clazz, Serializable id) {Session session = this.sessionFactory.openSession();Object obj = session.get(clazz, id);session.close();return obj;}@Overridepublic void delete(Object obj) {Session session = this.sessionFactory.openSession();session.beginTransaction();session.delete(obj);session.getTransaction().commit();session.close();}}

在action类中的dao对象一定要加入JavaBean(get和set)不然无法获取到注入的sessionFactory
