        JobCoreConfiguration.Builder builder = JobCoreConfiguration.newBuilder(serviceMonitor.getClass().getName()
                , cron, shardingTotalCount);
        JobCoreConfiguration jobCoreConfiguration = builder
                .shardingItemParameters(shardingItemParameters)
                .description(jobDescription)
                .jobParameter(jobParameter)
