即使在成功之后，Spring Batch也会重复块大小为1的步骤

Question

摘要：即使读取器/处理器/写入器成功，作业也会重新启动/重试。

我的步骤定义如下：

        return stepBuilder.get("job.transaction-export.step1")
            // .startLimit(stepStartLimit)
            .<AfxEntity, AfxEntity> chunk(chunkSize)
            .reader(reader)
            .processor(processor)
            .writer(writer)
            // .faultTolerant()
            // .backOffPolicy(exponentialRandomBackOffPolicy)
            // .retry(HttpServerErrorException.class)
            // .retry(UnknownHttpStatusCodeException.class)
            // .retry(ResourceAccessException.class)
            // .noRetry(HttpClientErrorException.class)
            .build();
