springboot之定时任务（elaticjob）

springboot之定时任务（elaticjob）

1.导入所依赖的jar包
          <dependency>
            <groupId>com.dangdang</groupId>
            <artifactId>elastic-job-lite-spring</artifactId>
            <version>2.1.5</version>
            </exclusions>
        </dependency>
2.在配置文件（application.yml）中设置定时任务执行策略

elaticjob:
  daycron : 0 */30 * 1 * ?
  monthcron : 0 */30 * 1 * ?
  transferCron : 0 */30 * 1 * ?
  shardingTotalCount : 1
  shardingItemParameters : 0=A
  dayJobName: demo-etl-day-task
  monthJobName: demo-etl-month-task
  riskOriginalHisJobName:demo-roiginalHis-day-task
  zookeeper:
    namespace: job-demo-local
    server-lists: 127.0.0.1:8080
    sessiontimeout: 30000 

3.配置监听器

/**
 * ElasticJob监听器配置类
 */
@Slf4j
public class EasticJobListenerDemo implements ElasticJobListener {

    @Override
    public void beforeJobExecuted(ShardingContexts shardingContexts) {
        long beginTime = System.currentTimeMillis();
        log.info(“===>{} JOB BEGIN TIME: {} <===”, shardingContexts.getJobName(),
                ToolUtils.timeStamp2Date(beginTime + “”, “”));
    }

    @Override
    public void afterJobExecuted(ShardingContexts shardingContexts) {
        long endTime = System.currentTimeMillis();
        log.info(“===>{} JOB END TIME: {},TOTAL CAST: {} <===”, shardingContexts.getJobName(),
                ToolUtils.timeStamp2Date(endTime + “”, “”));
    }

}

4.配置ElasticJobConfig，设置监听器

/**
 * ElasticJob定时任务配置类
 */
@Configuration
public class ElasticJobConfig {

    @Value(“${elaticjob.dayJobName}”)
    private String                  dayJobName;

    @Value(“${elaticjob.monthJobName}”)
    private String                  monthJobName;

    @Value(“${elaticjob.riskOriginalHisJobName}”)
    private String                  riskOriginalHisJobName;

    @Inject
    private ZookeeperRegistryCenter regCenter;

    /**
     * 配置任务监听器
     * 
     * @return
     */
    @Bean
    public ElasticJobListener elasticJobListener() {
        return new EasticJobListenerDemo ();
    }

    /**
     * 配置任务详细信息
     * 
     * @param jobClass
     * @param cron
     * @param shardingTotalCount
     * @param shardingItemParameters
     * @return
     */
    private LiteJobConfiguration getLiteJobConfiguration(final Class<? extends SimpleJob> jobClass,
            final String cron,
            final int shardingTotalCount,
            final String shardingItemParameters,
            final String jobName) {
        return LiteJobConfiguration.newBuilder(new SimpleJobConfiguration(
                JobCoreConfiguration.newBuilder(jobName, cron, shardingTotalCount)
                        .shardingItemParameters(shardingItemParameters).build(),
                jobClass.getCanonicalName())).overwrite(true).build();
    }

    @Bean(initMethod = “init”)
    public JobScheduler simpleJobScheduler(final CountryRiskIndexDayJob simpleJob,
            @Value(“${elaticjob.daycron}”) final String cron,
            @Value(“${elaticjob.shardingTotalCount}”) final int shardingTotalCount,
            @Value(“${elaticjob.shardingItemParameters}”) final String shardingItemParameters) {
        EasticJobListenerDemo elasticJobListener = new EasticJobListenerDemo ();
        return new SpringJobScheduler(simpleJob, regCenter,
                getLiteJobConfiguration(CountryRiskIndexDayJob.class, cron, shardingTotalCount, shardingItemParameters,
                        dayJobName),
                elasticJobListener);
    }

    @Bean(initMethod = “init”)
    public JobScheduler simpleJobScheduler2(final CountryRiskIndexMonthJob simpleJob,
            @Value(“${elaticjob.monthcron}”) final String cron,
            @Value(“${elaticjob.shardingTotalCount}”) final int shardingTotalCount,
            @Value(“${elaticjob.shardingItemParameters}”) final String shardingItemParameters) {
        EasticJobListenerDemo  elasticJobListener = new EasticJobListenerDemo ();
        return new SpringJobScheduler(simpleJob, regCenter,
                getLiteJobConfiguration(CountryRiskIndexMonthJob.class, cron, shardingTotalCount,
                        shardingItemParameters,
                        monthJobName),
                elasticJobListener);
    }

    @Bean(initMethod = “init”)
    public JobScheduler simpleJobScheduler3(final RiskOriginalDataHisJob simpleJob,
            @Value(“${elaticjob.transferCron}”) final String cron,
            @Value(“${elaticjob.shardingTotalCount}”) final int shardingTotalCount,
            @Value(“${elaticjob.shardingItemParameters}”) final String shardingItemParameters) {
        EasticJobListenerDemo elasticJobListener = new EasticJobListenerDemo ();
        return new SpringJobScheduler(simpleJob, regCenter,
                getLiteJobConfiguration(RiskOriginalDataHisJob.class, cron, shardingTotalCount, shardingItemParameters,
                        riskOriginalHisJobName),
                elasticJobListener);
    }
}
