Mry淡忘 2015-10-15 10:10:16
Sessionfactory.getCurrentSession.save()无法添加数据,具体配置及Dao层代码如下:

</beans>


Dao层java代码
package com.izhuyh.Dao.impl;

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

import com.izhuyh.Dao.UserDao;
import com.izhuyh.Entity.User;

@Repository
public class UserDaoImpl implements UserDao{


@Autowired
private SessionFactory sf;

@Override
public boolean addUser(User u) {
// TODO Auto-generated method stub
boolean flag=false;
try {
Session s = sf.getCurrentSession();
System.out.println("是否已经获得Session:"+s.isOpen());
s.saveOrUpdate(u);
flag = true;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}finally{
sf.close();
}

return flag;
}

}

运行结果没有报错,后台输出
是否已经获得Session:true
Hibernate: select user_.uuid, user_.userid as userid2_0_, user_.name as name3_0_, user_.age as age4_0_ from user user_ where user_.uuid=?
true
