Quartz任务调度

结合Spring、Quartz等框架，以注解的方式实现任务调度。
在作业四（Spring整合Hibernate）基础上添加任务调度的功能，实现在每周2凌晨1点统计数据库中蛋糕总数的功能。
将统计结果输出到控制台。
要求提交相关配置文件和类文件。
提示：任务调度相关的dao方法中，打开session使用：sessionFactory.openSession();

CakeCountDao.java：

package com.lrf.cakeonline.quartz.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.query.Query;
import org.springframework.stereotype.Repository;

@Repository
public class CakeCountDao {

	@Resource
	private SessionFactory sessionFactory;
	
	public int countCake() {
		Session session = this.sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();
		Query query = session.createQuery("select count(*) from cake");
		transaction.commit();
		int count = ((Number)query.uniqueResult()).intValue();
		session.close();
		return count;
	}
	
}

CakeCountService.java：

package com.lrf.cakeonline.quartz.service;

import javax.annotation.Resource;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

import com.lrf.cakeonline.quartz.dao.CakeCountDao;

@Service
public class CakeCountService {

	@Resource
	private CakeCountDao cakeCountDao;
	
	@Scheduled(cron = "0 0 1 ? * TUE")
	public void cakeCount() {
		int cakeNum = this.cakeCountDao.countCake();
		System.out.println(cakeNum);
	}
	
}
