问题描述
使用Spring Integration SFTP功能和入站通道适配器，可以下载远程文件进行处理。
虽然我使用以下启动和停止例程来启动/停止入站通道适配器。
public void startInboundAdapter() throws ApplicationException {
SourcePollingChannelAdapter streamInboundAdapter = appContext.getBean("streamInboundAdapter",SourcePollingChannelAdapter.class);
streamInboundAdapter.start();
}
public void stopInboundAdapter() throws ApplicationException {
SourcePollingChannelAdapter streamInboundAdapter = appContext.getBean("streamInboundAdapter",SourcePollingChannelAdapter.class);
streamInboundAdapter.stop();
}
但是在所有文件处理完成之后，调用stop inbound adapter之后观察到异常。我被困在这里，正在寻找解决方案，请提出建议。
