在前面Struts2和Hibernate4的整合基础上，对Spring4进行整合，网上参考的大概都是Spring4+Hibernate3或者基于MyEclispe的，这里把自己研究后的配置和大家分享一下。

本次相关的版本如下：

Spring ： spring-framework-4.0.1.RELEASE

1.将相关的jar包导入：

1.1libs目录下包含所有的jar包（不需要复制结尾为sources和javadoc的jar包）到SSHProject项目的lib目录

技术分享

1.2 Hibernate内lib/optional/c3p0下的c3p0-0.9.2.1.jar复制到lib不目下

技术分享

2.添加Spring的配置信息，放在WEB-INF下（都为Spring4的配置和Spring3的参数不同，大家注意一下相应的class名字）。

applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

        </property>
    </bean>

    <!-- more bean definitions go here -->

</beans>

3.删除Hibernate的配置文件Hibernate.cfg.xml和工厂类HibernateSesseionFactory类。他们的工作已经交给Spring去做，已经不再有用。

4.修改相应的类

接口类BaseDao.java:

package com.tiny.ssh.dao;

import org.hibernate.HibernateException;

public interface BaseDao {

    public void saveObject(Object obj) throws HibernateException;

}

实现类UserDao.java (注意这里不一样的地方，由于Hibernate4不在有getCurrentSession()方法，要用openSession()来代替):

package com.tiny.ssh.daoImpl;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

import com.tiny.ssh.dao.BaseDao;

public class UserDao implements BaseDao {
    
    private SessionFactory sessionFactory;  
      
    public SessionFactory getSessionFactory() {  
        return sessionFactory;  
    }  
  
    @Autowired  
    public void setSessionFactory(SessionFactory sessionFactory) {  
        this.sessionFactory = sessionFactory;  
    }  
  
    private Session getCurrentSession() {  
        return sessionFactory.openSession();  // 需要用openSession()
    }
    
    @Override
    public void saveObject(Object obj) throws HibernateException {
        this.getCurrentSession().save(obj);  
    }

}

业务逻辑实现类UserManagerImpl.java：

package com.tiny.ssh.serviceImp;

import org.hibernate.HibernateException;
import org.springframework.beans.BeanUtils;

import com.tiny.ssh.beans.User;
import com.tiny.ssh.dao.BaseDao;
import com.tiny.ssh.forms.UserForm;
import com.tiny.ssh.service.UserManager;

public class UserManagerImpl implements UserManager {

    private BaseDao dao;

    public void setDao(BaseDao dao) {
        this.dao = dao;
    }

    @Override
    public void regUser(UserForm userForm) throws HibernateException {
        User user = new User();
        BeanUtils.copyProperties(userForm, user);
        dao.saveObject(user);
    }

}

用户注册Action类RegisterAction.java :

package com.tiny.ssh.action;

import com.opensymphony.xwork2.ActionSupport;
import com.tiny.ssh.forms.UserForm;
import com.tiny.ssh.service.UserManager;

public class RegisterAction extends ActionSupport {

    private static final long serialVersionUID = 1L;

    private UserForm user;

    private UserManager userManager;

    public UserForm getUser() {
        return user;
    }

    public void setUser(UserForm user) {
        this.user = user;
    }

    public void setUserManager(UserManager userManager) {
        this.userManager = userManager;
    }

    public String execute() {
        try {
            userManager.regUser(user);
            return SUCCESS;

        } catch (Exception e) {
            e.printStackTrace();
            return ERROR;
        }
    }

}

加入Listener后的web.xml

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
