Spring Batch重试FixedBackOffPolicy无法正常运行

Question

我正在研究 Spring Batch Retry机制。我已经实现了以下代码，并将FixedBackOffPolicy设置为每10秒启动一次重试机制。

但是，当我对此进行测试时，发现下面的FixedBackOffPolicy backOffPolicy.setBackOffPeriod((Long.valueOf(retryPeriod) * 1000))代码无法正常工作。它没有考虑回退超时（我假设这是两次重试计数之间的持续时间）。

public class ConnectionRetryCallback implements RetryCallback {
    private static Logger logger = Logger.getLogger(ConnectionRetryCallback.class);

    @Autowired
    private ABCBatchFilesTasklet tasklet;


    private Set<String> abcFileNames;
    private ChunkContext paramChunkContext; 

    public ConnectionRetryCallback(Set<String> abcFileNames, ABCBatchFilesTasklet tasklet, ChunkContext paramChunkContext) {
        this.abcFileNames = abcFileNames;
        this.tasklet = tasklet;
        this.paramChunkContext = paramChunkContext;
    }

    @Override
    public Object doWithRetry(RetryContext retryContext) throws Throwable {
        logger.debug("ConnectionRetryCallback | doWithRetry");
        return tasklet.executeShellScript(abcFileNames, paramChunkContext);
    }
}

从status = 2开始的位置，调用以下逻辑。在我的情况下，status = 2，假定为失败并调用重试机制。

retryCount++;

ConnectionRetryCallback callback = new ConnectionRetryCallback(abcFileNames, this, paramChunkContext);
try {
    long lStartTime = System.nanoTime();
    if(retryCount <= Integer.valueOf(retryshellscriptExeCount)) {
        logger.info("Retry Mechanism to be applied ="+!MapUtils.isEmpty(fileSendStatusMap));
        logger.info("Retry toABC File, Retry Count = " + retryCount+", Retry to send these files ="+abcFileNames);

        final FixedBackOffPolicy backOffPolicy = new FixedBackOffPolicy();
        backOffPolicy.setBackOffPeriod((Long.valueOf(retryPeriod) * 1000)); // 1 sec = 1000 millisec

        retryTemplate.setBackOffPolicy(backOffPolicy);
        retryTemplate.execute(callback);
    }else {
        logger.info("Retry Consumed");
    }
} catch (Throwable e) {
    logger.error(e.getMessage());
}
