线程池配置

executor.core-pool-size=10
executor.max-pool-size=20
executor.queue-capacity=200
executor.keep-alive-seconds=60
executor.thread-name-prefix=taskExecutor-
executor.wait-for-tasks-to-complete-on-shutdown=true
executor.await-termination-seconds=60

##定时任务开关配置
order.insurance.email.scheduling.enabled=true

import org.springframework.boot.context.properties.ConfigurationProperties;

定时任务

@Configuration
public class OrderInsuranceEmailConfiguration {

    @Configuration
    @ConditionalOnProperty("order.insurance.email.scheduling.enabled")
    public static class Scheduling {
        private final Logger logger = LoggerFactory.getLogger(getClass());

        }
    }
}

动态定时任务

    @Autowired

                .getStatus())).fetchOne();
            if (notice == null) {
                logger.info("未设置运单运费贷通知提醒执行计划");
                return;
            }
            String cron = "0 minute hour * * ?";
            cron = cron.replace("minute", notice.getRemindMinute() + "").replace("hour", notice.getRemindHour() + "");
//            String cron = "* * * * * ?";
            taskRegistrar.setTaskScheduler(taskScheduler);
            taskRegistrar.getScheduler().schedule(new MyRunnable(), new CronTrigger(cron));
            logger.info("初始化运单运费贷通知提醒执行计划完成");
        } catch (Exception e) {
            logger.error("运单运费贷通知提醒执行计划异常", e);
        }
    }

    private class MyRunnable implements Runnable {

        @Override
