Question

我在sessionFactory.getCurrentSession（）中得到错误nullpointerexception;

Spring Framework 4.0
Glassfish 4.1
hibernate 4.3.6.Final

当我调用Session session = sessionFactory.getCurrentSession（）;我在glassfish服务器日志中遇到错误，但是SetSessionFactory是由Spring设置的。我的代码有什么问题。请帮忙！：）

它是Spring @Component

package service;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ApplicationScoped;

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

import model.Payments;

@Component
@ManagedBean(name = "paymentsService")
@ApplicationScoped
@Repository
public class PaymentsService {


    private SessionFactory sessionFactory ;

    public PaymentsService()
    {

    }


    public PaymentsService(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    @Autowired
    public void setSessionFactory( SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

   // @Transactional
    public void register(){

        Session session = sessionFactory.getCurrentSession();

    }
}

它的主要成员@ManagedBean

package backbean;

import java.io.Serializable;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.context.FacesContext;
import javax.faces.bean.SessionScoped;

import model.Payments;
import service.PaymentsService;


@ManagedBean
@ApplicationScoped
public class Paymentsbeen implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 7719279452314113041L;


    public String register() {

        paymentsService.register();


    }

}

它的Spring配置文件
