Spring Batch如何配置失败作业的重试周期

@Bean
public Job myJob(Step myStep) {
    return jobBuilderFactory.get("myJob")
            .start(myStep)
            .build();
}

@Bean
public Step myStep(ItemReader<String> reader, ItemProcessor<String, String> processor, ItemWriter<String> writer) {
    return stepBuilderFactory.get("myStep")
            .<String, String>chunk(10)
            .reader(reader)
            .processor(processor)
            .writer(writer)
            .faultTolerant()
            .retry(SimpleRetryPolicy())
            .build();
}

@Bean
public RetryPolicy simpleRetryPolicy() {
    SimpleRetryPolicy retryPolicy = new SimpleRetryPolicy();
    retryPolicy.setMaxAttempts(3);
    retryPolicy.setRetryableExceptions(Arrays.asList(IOException.class));
    return retryPolicy;
}
