我们可以使用 apache Camel 端点将文件从 FTP 服务器移动到本地目录吗？

Question

我想知道是否可以使用 apache Camel 端点属性将文件从 FTP 服务器移动或下载到本地目录？

我已经搜索过这个主题，但找不到任何可以帮助我的东西。另外，我不确定其可行性。

端点 URI=

sftp://[email protected]/outgoingFolder?password=*****&throwExceptionOnConnectFailed=true&maximumReconnectAttempts=0&stepwise=false&fastExistsCheck=true&disconnect=true&consumer.delay=300000&passiveMode=true

我使用“&move=C: old”作为属性，但它不起作用，并且出现以下错误

WARN - [SftpConsumer:213] Consumer Consumer[sftp://[email protected]/outgoingFolder?consumer.delay=300000&disconnect=true&fastExistsCheck=true&maximumReconnectAttempts=0&move=C%3A%5C%5Cfolders&passiveMode=true&password=xxxxxx&stepwise=false&throwExceptionOnConnectFailed=true] failed polling endpoint: Endpoint[sftp://[email protected]/outgoingFolder?consumer.delay=300000&disconnect=true&fastExistsCheck=true&maximumReconnectAttempts=0&move=C%3A%5C%5Cfolder&passiveMode=true&password=xxxxxx&stepwise=false&throwExceptionOnConnectFailed=true].

Answer 1

不，&move 选项用于在远程文件系统范围内移动文件。

用这个代替：

from("sftp://[email protected]/outgoingFolder?password=*****&throwExceptionOnConnectFailed=true&maximumReconnectAttempts=0&stepwise=false&fastExistsCheck=true&disconnect=true&consumer.delay=300000&passiveMode=true")
.to("file:C:\\folder");

Answer 2

您需要先将文件下载到本地目录，然后再移动它。

from("sftp://[email protected]/outgoingFolder?password=*****")
.to("file:D:\\folder");
