**quartz.properties用于存放quart的配置  
job.xml 用于存放定时任务job**  
将这两个文件放在com.zte.quartzTest目录底下即可

**pom.xml**

**HelloJob.java**

package com.zte.quartzTest;

    		Date date = new Date();
    	    SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    	    System.out.println("现在的时间:"+ sf.format(date));
    	    
    	    JobDetail jobDetail = jobExecutionContext.getJobDetail();  
            JobKey jobKey = jobDetail.getKey();  
            String jobName = jobKey.getName();  
            String jobGroup = jobKey.getGroup();
            
            System.out.println(jobName);
            System.out.println(jobGroup);
    	}
    }

**Test.java**

    		try

    			StdSchedulerFactory schedulerFactory = new StdSchedulerFactory();
    			schedulerFactory.initialize("quartz.properties");
                Scheduler scheduler = schedulerFactory.getScheduler();  
                
                scheduler.start();  
                System.out.println(scheduler.getJobGroupNames());
    // Thread.sleep(5L * 1000L); 
    // scheduler.shutdown(true); 
            }
    		catch (Exception e)
    		{   
                e.printStackTrace();  
            } 
    
    
    	}
    }
