Quartz 使用

package s.simple;
import org.quartz.*;
import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @Title: HelloJob
 * @ProjectName quartz
 * @date 2019/6/2513:52
 * 实现任务逻辑的接口Job

public class HelloJob implements Job {

        String format = sfd.format(date);
        System.out.println("当前系统时间: "+ format);

        // 值获取2种方式
        // 1.获取jobDetailMap 和 TriggerDataMap
        JobDataMap jobDataMap = jobExecutionContext.getTrigger().getJobDataMap();
        JobDataMap jobDataMap1 = jobExecutionContext.getJobDetail().getJobDataMap();
        // 合并后的Map Trgger会覆盖Detail中的key
        JobDataMap mergedJobDataMap = jobExecutionContext.getMergedJobDataMap();
        String message1 = mergedJobDataMap.getString("message");
        // 2.传值方式也可以通过属性方式,需要定义set方法
        System.out.println(testParam);

        // 获取开始和结束时间
        Trigger trigger = jobExecutionContext.getTrigger();
        Date startTime = trigger.getStartTime();
