Spriongboot+quartz定时任务

y需求: 需要一个定时任务,比如 2019-5-10 10:00   执行一次期初库存推送的功能~

Spring自带的@Schedule() 的cron表达式不支持年份,所以考虑一下quartz定时任务.

1.pom文件

  <!-- 定时任务-->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.1</version>
        </dependency>

2.Job

import org.qua

rtz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

/**
 * 实现Job接口
 *
 *
 */
public class SchedulerQuartzJob1 implements Job {
    private void before(){
        System.out.println("任务开始执行");
    }

    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        before();
        System.out.println("开始："+System.currentTimeMillis());
        // TODO 业务

        System.out.println("quartz定时任务往这里写~~~~~~~~~~");

        System.out.println("结束："+System.currentTimeMillis());
        after();
    }

    private void after(){
        System.out.println("任务开始执行");
    }

}

3.任务调用处理
