springboot实现apollo中quartz动态配置的两种实现方式

第一种实现方式:

关于如何实现在apollo上动态开启或关闭定时任务
直接上代码:

@Slf4j
@Configuration
public class QuartzConfig {
     
    @Resource
    //获取配置文件属性的类,这里有多种方式,用你喜欢的方式即可
    private QuartzPropertiesUntil quartzPropertiesUntil;


    @Resource
    private Scheduler scheduler;

    private static final String PREFIX = "quartz.";

    @ApolloConfigChangeListener("1000")//quartz在appolo中的namespace
    private void onRefresh(ConfigChangeEvent changeEvent) {
     
        refreshKeys(changeEvent);
    }

    private void refreshKeys(ConfigChangeEvent changeEvent) {
     
        for (String key : changeEvent.changedKeys()) {
     
            if (StringUtils.startsWithIgnoreCase(key, PREFIX)) {
     
                log.error("changed value {} ", changeEvent.getChange(key));
                String newValue = changeEvent.getChange(key).getNewValue();
                switch (key){
     
                    case "quartz.enabled":
                        boolean enabled = Boolean.parseBoolean(newValue);
                        isEnabled(enabled);
                        break;
                    case "quartz.enabled-job1":
                        boolean enabledJob1 = Boolean.parseBoolean(newValue);
                        isEnabledJob1(enabledJob1);
                        break;
                    case "quartz.enabled-job2":
                        boolean enabledJob2 = Boolean.parseBoolean(newValue);
                        isEnabledJob2(enabledJob2);
                        break;
                    default:
                        break;
                }
            }
        }
    }
	
	//定时任务总开关
    private void isEnabled(boolean enabled) {
     
        if (enabled) {
     
            try {
     
                scheduler.resumeAll();
            } catch (SchedulerException e) {
     
                log.error("enabledSchedule start failed:" + e.getMessage());
            }
        } else {
     
            try {
     
                scheduler.pauseAll();
            } catch (SchedulerException e) {
     
                log.error("enabledSchedule pauseAll failed:" + e.getMessage());
            }
        }
    }

    @Bean
    void enabledSchedule() {
     
        Boolean enabled = quartzPropertiesUntil.getEnabled();
        isEnabled(enabled);
    }

    @Bean
    void enabledJob1() {
     
        Boolean enabledJob1 = quartzPropertiesUntil.getEnabledJob1();
        isEnabledJob1(enabledJob1);
    }
	//任务job1开关
    private void isEnabledJob1(Boolean enabledJob1) {
     
        JobKey jobKey = new JobKey(CacheConst.JOB1_TASK);//定时任务Job1标识常量
        if (enabledeJob1) {
     
            try {
     
                scheduler.resumeJob(jobKey);
            } catch (SchedulerException e) {
     
                log.error("resumeJob1 failed:" + e.getMessage());
            }
        } else {
     
            try {
     
                scheduler.pauseJob(jobKey);
            } catch (SchedulerException e) {
     
                log.error("pauseJob1 failed:" + e.getMessage());
            }
        }
    }

    @Bean
    void enabledJob2() {
     
        Boolean enabledJob2 = quartzPropertiesUntil.getEnabledJob2();
        isEnabledJob2(enabledJob2);
    }
	//任务job2开关
    private void isEnabledJob2(Boolean enabledJob2) {
     
        JobKey jobKey = new JobKey(CacheConst.JOB2_TASK);//定时任务Job2标识常量
        if (enabledJob2) {
     
            try {
     
                scheduler.resumeJob(jobKey);
            } catch (SchedulerException e) {
     
                log.error("resumeJob2 failed:" + e.getMessage());
            }
        } else {
     
            try {
     
                scheduler.pauseJob(jobKey);
            } catch (SchedulerException e) {
     
                log.error("pauseJob2 failed:" + e.getMessage());
            }
        }
    }

}

第二中实现方式:

关于如何实现在apollo上动态设置cron表达式
直接上代码:

@Slf4j
@Component(CacheConst.JOB1_TASK)//定时任务Job1标识常量
public class JOB1Task implements SchedulingConfigurer, Ordered {
     
    @Resource
    private QuartzPropertiesUntil quartzPropertiesUntil;

    @Resource
    private IService iService;//业务接口

    @Override
    public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
     
        Runnable runnable = () -> {
     
            log.info("Job1Task-------- {}", DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss"));
            iService.serviceMethod();//业务方法
        };

        Trigger trigger = triggerContext -> {
     
            CronTrigger cronTrigger = new CronTrigger(quartzPropertiesUntil.getJob1Cron());
            return cronTrigger.nextExecutionTime(triggerContext);
        };
        scheduledTaskRegistrar.addTriggerTask(runnable, trigger);
    }

    @Override
    public int getOrder() {
     
        return LOWEST_PRECEDENCE;
    }
}

apollo是很好的分布式配置工具,个人觉得比spring自带的config要好用,好用是好用,但是有些配置修改是不能直接生效的,需要重启服务才能生效,这就失去了apollo的动态配置的作用,这个时候我们需要在项目代码中添加配置类来动态刷新配置,来弥补这个缺陷,quartz定时任务的配置就是一个例子。
在我们开发项目的时候,开发环境和生产环境所需要的日志输出级别一般是不一样的,而日志的输出级别在apollo中的配置也无法动态刷新,所以需要配置动态刷新类,下一篇发文我们来谈谈springboot结合apollo如何动态刷新日志级别
