问题描述

首先我遇到了以下错误: GenericFileOperationFailedException - Cannot change directory to: ..] 我已经通过添加stepwise=false到端点字符串来修复它:

sftp://sales.data.com:22/data/100?fileName=20190410.dat.gz&password=xxxxxx&stepwise=false&username=UserName

之后它因以下错误而失败,我找不到任何有关解决此问题的相关信息。什么可能导致这里的问题?

解决方案


在你的消费者上使用 readLock,让它等到文件完全被 FTP 编辑。在ftp 的 Camel 文档中,查找此选项:

  • 读锁改变

这个想法是:告诉 Camel 在看到文件时不要读取它,而是继续检查它是否在变大。只要它继续增长,骆驼就会等待。您可以更改相关选项以确定等待多长时间等。在该页面中搜索所有提及“readLock”以查找更多信息。
