SpringBoot 整合 Quartz
先说为什么会用Quartz吧, 业务需求是在一个时间段比如 12:00---16:00,开始前一个小时需要提醒一次用户,结束前一个小时需要用户,12:00整的时候也需要提醒一次用户,并且可能多个存在多个这样相同的任务.(所以就需要一个任务时间不会错乱的,timertask可能会导致任务时间错乱,所以首先就排除,quartz每一个任务都是一个新的线程,因为使用到了线程池+时间轮),整合如下:
1.导入依赖
org.springframework.boot
spring-boot-starter-quartz
2.6.6
因为这里我选择了把任务持久化到数据库,防止宕机过后任务丢失(记得更换自己的数据库账号密码)

# I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

} 这里再提供一个 Date类型转换Cron表达式的工具类,这样就能自定义时间了.
package com.ruoyi.system.util;
import java.text.SimpleDateFormat;
import java.util.Date;
public class TimeUtil {
private static String formatDateByPattern(Date date, String dateFormat){
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
String formatTimeStr = null;
if (date != null) {
formatTimeStr = sdf.format(date);
}
return formatTimeStr;
}
/**
* Date转为cron表达式
* @param date
* @return
*/
public static String getCron(java.util.Date date){
String dateFormat="ss mm HH dd MM ? yyyy";
return formatDateByPattern(date, dateFormat);
}
}
接下来只需要在你使用的地方注入service调用方法即可
@Autowired
private QuartzService quartzService;
quartzService.addJob(Msmjob.class.getName(),Msmjob.class.getName(),
"duanxin", TimeUtil.getCron(hsBuildingTask.getStartTime()),null);
数据库也有了
