Struts2.3.4+Hibernate3.6+Spring3.0.5框架整合(新手看看)

工欲善其事，必先利其器，相关的下载就不多说，数据库是MySql5.1

新建一个WEB工程，将如下的包导入工程的WEB-INF/lib目录下，

导入包的说明：struts2.3.4中因为使用c3p0连接数据库所以导入了c3p0.jar，其它的就是struts2.3.4的基本的包的导入，上图中的slf4j-nop-1.6.1.jar导不导入影响不大，然后导入Hibernate的核心包，以及Spring中dist目录下的所有包，去掉重复的包，保留较高的版本，结果如上图所示，如果你想使用struts2，Hibernate以及Spring的更多的功能，请导入相关的包。

下面是web.xml文件的配置

web.xml

数据库Dao 接口：UserDao

package cn.zj.qiao.interfaces;

import cn.zj.qiao.entity.vo.User;


public interface UserDao {
    public Long addUser(User user);

}

Dao的实现类：UserDaoimpl

package cn.zj.qiao.spring.dao.userimpl;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;

import cn.zj.qiao.entity.vo.User;
import cn.zj.qiao.interfaces.UserDao;

public class UserDaoImpl implements UserDao {
    
    private HibernateTemplate ht = null;
    private SessionFactory sessionFactory;
    
    public void setSessionFactory(SessionFactory sessionFactory){
        this.sessionFactory = sessionFactory;
    }
    public SessionFactory getSessionFactory(){
        return sessionFactory;
    }
    
    public HibernateTemplate getHibernateTemplate(){
        if(ht == null){
            ht = new HibernateTemplate(sessionFactory);
        }
        return ht;
    }
    @Override
    public Long addUser(User user) {
        return (Long)getHibernateTemplate().save(user);
    }
}
