Quartz regular tasks implemented by spring

Quartz introduction:

Quartz is OpenSymphony open source organization and an open source project in Job scheduling field, it can be combined with J2EE and J2SE applications can also be used alone. Quartz can be used to create simple or run ten, one hundred, or even tens of thousands of Jobs such a complex program. And we write Java programs often write some regular tasks to perform, such as a month to perform a few numbers thing, do something every day in the morning, or what method is performed once a day, then I put a simple, entry Quartz examples put to, it can be run directly, are additions and deletions to change search the Quartz series, can for beginners, there is a general understanding.

QuartzManager (CRUD method):

package com.joyce.quartz;
 
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;

	/**

	@SuppressWarnings("rawtypes")
	public static void addJob(String jobName, Class cls, String time) {

		}
	}
	/**

	/**
	 * 移除一个任务(使用默认的任务组名，触发器名，触发器组名)
	 * @param jobName
	 */
	public static void removeJob(String jobName) {

		} catch (Exception e) {

	/**
	 * 启动所有定时任务
	 */
	public static void startJobs() {

QuartzJob (task execution classes):

package com.joyce.quartz;
 
import java.text.SimpleDateFormat;
import java.util.Date;
 
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
 
/**
 * 任务执行类
 */
public class QuartzJob implements Job {
 
	@Override
	public void execute(JobExecutionContext content) throws JobExecutionException {
		System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())+ "★★★★★★★★★★★");  
		String jobName = content.getJobDetail().getName();
		JobDataMap dataMap = content.getJobDetail().getJobDataMap();
		String param = dataMap.getString("param");
		System.out.println("传递的参数是="+param +"任务名字是="+jobName);
	}
}

QuartzTest (scheduled task test class):

package com.joyce.quartz.main;
 
import java.text.SimpleDateFormat;
import java.util.Date;
 
import com.joyce.quartz.QuartzJob;
import com.joyce.quartz.QuartzManager;
 
public class QuartzTest {
	public static void main(String[] args) {
		try {
			String job_name = "动态任务调度";
			System.out.println("【任务启动】开始(每10秒输出一次)...");  
			QuartzManager.addJob(job_name, QuartzJob.class, "0/10 * * * * ?");
			Thread.sleep(5000);
			System.out.println("【修改时间】开始(每2秒输出一次)...");  
			QuartzManager.modifyJobTime(job_name, "10/2 * * * * ?");  
			Thread.sleep(6000);  
			System.out.println("【移除定时】开始...");  
			QuartzManager.removeJob(job_name);  
			System.out.println("【移除定时】成功");  
			System.out.println("【再次添加定时任务】开始(每10秒输出一次)...");  
			QuartzManager.addJob(job_name, QuartzJob.class, "*/10 * * * * ?");  
			Thread.sleep(60000);  
			System.out.println("【移除定时】开始...");  
			QuartzManager.removeJob(job_name);  
			System.out.println("【移除定时】成功");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public static String formatDateByPattern(Date date,String dateFormat){  
        SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);  
        String formatTimeStr = null;  
        if (date != null) {  
            formatTimeStr = sdf.format(date);  
        }  
        return formatTimeStr;  
    }  
	public static String getCron(java.util.Date  date){  
	    String dateFormat="ss mm HH dd MM ? yyyy";  
	    return formatDateByPattern(date, dateFormat);  
	 }
