springBoot整合quartz实现定时任务

写在前面的话:在工作中遇见了几次这个需要定时进行特定操作的需求,就做个记录方便参考。本文仅作参考。

SpringBoot

导入包

        <!-- spring boot - quartz -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

启动类添加扫描注释

@EnableScheduling

job代码


/**
 * <b>创建人:</b>surfingCat<br>
 * <b>类描述:</b><br>
 * <b>创建时间:</b>2021/3/01 16:10<br>
 */
@Component
public class PunchCardJob implements SchedulingConfigurer, Runnable, Trigger {

    private final Logger log = LoggerFactory.getLogger(getClass());

    @Autowired
    private PunchCardJobService punchCardJobService;

// 读取配置
    @Value("${job.interval}")
    public String cronString;

    @Override
    public void run() {
        try{
// 执行的任务逻辑
            punchCardJobService.upDatePunchCardTaskStatus();
        }catch (Exception e){
            log.error("定时job任务时出错",e);
        }
    }

    @Override
    public Date nextExecutionTime(TriggerContext triggerContext) {
        log.debug("定时job任务CronTrigger设定={}", cronString);
        return new CronTrigger(cronString).nextExecutionTime(triggerContext);
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
        scheduledTaskRegistrar.addTriggerTask(this, this);
    }
}

附Spring配置

导入包

		<dependency>
			<groupId>org.quartz-scheduler</groupId>
			<artifactId>quartz</artifactId>
			<version>2.2.1</version>
		</dependency>
		<dependency>
			<groupId>org.quartz-scheduler</groupId>
			<artifactId>quartz-jobs</artifactId>
			<version>2.2.1</version>
		</dependency>

spring-mvc配置

    <!-- job配置 -->
    <task:annotation-driven scheduler="qbScheduler" mode="proxy"/>
    <task:scheduler id="qbScheduler" pool-size="10"/>

job(多实例部署时提供一个任务抢占模式)

/**
 * <b>创建人:</b>surfingCat<br>
 * <b>类描述:</b>Job<br>
 * <b>创建时间:</b>2020-03-30 15:24<br>
 */
@Service("com.web.job.DeleteLogsJob")
@DisallowConcurrentExecution
public class DeleteLogsJob implements SchedulingConfigurer, Runnable, Trigger {

    private static final String DELETE_JOB_KEY = "asjcxvywjehq81etjs!@#e7dae1k2i(*&23qkj9";
    private final Logger log = LoggerFactory.getLogger(getClass());

    @Autowired
    @Qualifier("redisTemplate")
    private RedisTemplate<String, Object> jedisTemplate;

    @Resource
    private SysFlatDictBmo sysFlatDictBmo;

    @Resource
    private DeleteLogsJobBmoImpl deleteLogsJobBmo;

    @Override
    public void run() {
        boolean monopolyMode = false;
        try {
            // 抢占模式,并标记为true=已独占
            Boolean b = (Boolean) jedisTemplate.opsForValue().getAndSet(DELETE_JOB_KEY, true);
            monopolyMode = b != null && b.booleanValue();
        } catch (Exception ignore) {
            // ignore
        }
        // 若原值为true,则抢占失败,表示已被其他人独占
        if (monopolyMode) {
            log.debug("已被其他任务独占");
            return;
        }
        try {
            log.debug("系统定时-开始");
//            deleteLogsJobBmo.deleteOverdueLogs();
            log.debug("系统定时-结束");
        } catch (Exception e) {
            log.error("系统定时-异常", e);
        }
        try {
            // 独占模式释放,让其他人可以抢占
            jedisTemplate.opsForValue().getAndSet(DELETE_JOB_KEY, false);
        } catch (Exception ignore) {
            // ignore
        }
    }

    @Override
    public Date nextExecutionTime(TriggerContext triggerContext) {
        String cronString = sysFlatDictBmo.getter().DeleteLogsJobTime();
        log.debug("job任务CronTrigger设定={}", cronString);
        return new CronTrigger(cronString).nextExecutionTime(triggerContext);
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.addTriggerTask(this, this);
    }
