Java SFTP :: Apache Camel RemoteFileProducer 忽略异常

如何解决Java SFTP :: Apache Camel RemoteFileProducer 忽略异常

我有一个 Java 应用程序，在 WildFly 服务器上运行，该服务器使用 Apache Camel 3.7.3 连接到远程 SFTP 服务器。此应用程序将文件发送到 SFTP 服务器。 当我手动测试我的应用程序并将 50 个文件发送到远程服务器时，有时会丢失 1 个文件。

我做了一些调试，发现了以下方法，该方法由camel-ftp库中的RemoteFileProducer使用。

@Override
    public void handleFailedWrite(Exchange exchange,Exception exception) throws Exception {
        loggedIn = false;
        if (isstopping() || isstopped()) {
            // if we are stopping then ignore any exception during a poll
            LOG.debug("Exception occurred during stopping: {}",exception.getMessage());
        } else {
            LOG.warn("Writing file Failed with: {}",exception.getMessage());
            try {
                disconnect();
            } catch (Exception e) {
                // ignore exception
                LOG.debug("Ignored exception during disconnect: {}",e.getMessage());
            }
            // rethrow the original exception*/
            throw exception;
        }
    }

我无法到达 SFTP 服务器的文件生成了一个异常，其中包含以下堆栈跟踪：

由于某种原因，文件传输管道在目录的 ls() 方法期间关闭。 问题是 RemoteFileProducer 的 isstopped() 方法返回 true，它只记录异常消息但不抛出它。我不知道这是怎么来的。 因此，我的应用程序认为文件已成功传输，但事实并非如此。 所以我希望是否可以做一些类似重试机制的事情，以便在管道损坏时再次尝试发送文件，并且在重试 x 次后，我想抛出异常。
