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

I was wondering if it is possible to move or download a file from FTP server to a local directory using the apache camel endpoints properties?

I already searched this topic and couldn't find anything that could help me. Also, I'm not certain of its feasibility.

The endpoints URI=

sftp://user@ftp.com/outgoingFolder?password=*****&throwExceptionOnConnectFailed=true&maximumReconnectAttempts=0&stepwise=false&fastExistsCheck=true&disconnect=true&consumer.delay=300000&passiveMode=true

I used "&move=C:\\folder" as property but it didn't work and I get the following error

WARN - [SftpConsumer:213] Consumer Consumer[sftp://user@ftp.com/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://user@ftp.com/outgoingFolder?consumer.delay=300000&disconnect=true&fastExistsCheck=true&maximumReconnectAttempts=0&move=C%3A%5C%5Cfolder&passiveMode=true&password=xxxxxx&stepwise=false&throwExceptionOnConnectFailed=true]. Will try again at next poll.

No, &move option is intended for moving file in scope of remote filesystem.

Use this instead:

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