\#需要调度的服务层

package com.haiyi.service;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    public class QuartzService {
        public void Print(){
           Date date = new Date();  
           SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
           System.out.println("任务执行时间为: " + sf.format(date));  
        }
    }

\#任务调度执行类

package com.haiyi.bean;
    
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    import org.springframework.scheduling.quartz.QuartzJobBean;
    import org.springframework.stereotype.Component;
    
    import com.haiyi.service.QuartzService;
    
    @Component(value="printInfoJob")
    public class PrintInfoJob extends QuartzJobBean{
    	private QuartzService quartzService;
    	
    	public QuartzService getQuartzService() {
    		return quartzService;
    	}
    	
    	public void setQuartzService(QuartzService quartzService) {
    		this.quartzService = quartzService;
    	}
    
    	@Override
    	protected void executeInternal(JobExecutionContext arg0)
    			throws JobExecutionException {
    		// TODO Auto-generated method stub
    		this.quartzService.Print();
    	}
    }

\#简单测试类

package com.haiyi.test;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import com.haiyi.service.QuartzService;
    
    public class Test {
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		System.out.println("测试开始......");
    		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
    		System.out.println("测试结束......");
    	}
    
    }
