我正在使用Maven,Spring和Hibernate进行基于Web的项目。我遇到了一个问题。问题是每当我使用sessionFactory.getCurrentSession()它显示错误并且错误是
对于SessionFactory
类型,未定义getCurrentSession()方法
这是我的pom.xml

以下是有问题的DAO类:
package com.mahin.daos;
import java.util.List;
import org.apache.cxf.service.invoker.SessionFactory;
import org.hibernate.Session;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.mahin.models.Users;
@Repository
public class usersDAO implements WebChatDAOs{
@Autowired
private SessionFactory sessionFactory;
private Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
@Override
public void addUser(Users user) {
getCurrentSession().save(user);
}
@Override
public void updateUser(Users user) {
// TODO Auto-generated method stub
}
@Override
public Users getUser(int id) {
// TODO Auto-generated method stub
return null;
}
@Override
public void deleteUser(int id) {
// TODO Auto-generated method stub
}
@Override
public List<Users> getUsers() {
// TODO Auto-generated method stub
return null;
}
}
谁能说出问题是什么?
答案 0 :(得分:2)
您似乎导入了错误的SessionFactory
。使用:
import org.hibernate.SessionFactory;
而不是:
import org.apache.cxf.service.invoker.SessionFactory;
