我是在做spring3.2.1与hibernate4.2Final整合的时候出的这个bug，在网上找了很多资料仍然解决不了
我的这个项目只是想测试在Service层上加上一事务，当向数据库存入一个User的时候，在log里面加上记录
下面给出我的相关代码，实体类User、Logo以及相应的接口类UserDAO与LogDAO就不给出了，对于逻辑没有什么影响：
用于处理User的DAO层的类UserDAOImpl：
package com.edu.hpu.impl;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;
import com.edu.hpu.dao.UserDAO;
import com.edu.hpu.model.User;
@Component(value="u")
public class UserDAOImpl implements UserDAO {
private SessionFactory sessionFactory;
public void save(User user) {
Session s = sessionFactory.getCurrentSession();
s.save(user);
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Resource(name="sessionFactory")
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
}
用于处理Log的DAO层的类LogDAOImpl：
package com.edu.hpu.impl;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;
import com.edu.hpu.dao.LogDAO;
import com.edu.hpu.model.Log;
@Component(value="logDAO")
public class LogDAOImpl implements LogDAO {
private SessionFactory sessionFactory;
@Override
public void save(Log log) {
Session s = sessionFactory.getCurrentSession();
s.save(log);
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Resource
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
}
用于联合处理User与Log的Service层次的类UserService类：
package com.edu.hpu.service;
import javax.annotation.Resource;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.edu.hpu.dao.LogDAO;
import com.edu.hpu.dao.UserDAO;
import com.edu.hpu.model.Log;
import com.edu.hpu.model.User;
@Component(value="userService")
@Scope(value="singleton")
public class UserService {
private UserDAO userDAO;
private LogDAO logDAO;
@Transactional
public void save(User user) {
userDAO.save(user);
Log log = new Log();
log.setMsg("a user been add into database");
logDAO.save(log);
}
public UserDAO getUserDAO() {
return userDAO;
}
@Resource(name="u")
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public LogDAO getLogDAO() {
return logDAO;
}
@Resource(name="logDAO")
public void setLogDAO(LogDAO logDAO) {
this.logDAO = logDAO;
}
}
beans.xml里面的配置信息：

用于测试的Junit类：
package com.edu.hpu.sevice;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.edu.hpu.model.User;
import com.edu.hpu.service.UserService;
public class TestUser {
@Test
public void testSave() {
ApplicationContext acx = new ClassPathXmlApplicationContext("beans.xml");
UserService service = (UserService)acx.getBean("userService");
service.save(new User());
}
}

出现bug的地点，是在getCurrentSession()这个地方。。求指教。。。
