[英]Spring Integeration SFTP outbound gateway mget -R issue
we are trying to connect to SFTP server using spring integration [SFTP outbound-gateway] to download all files with the following directory expression '/*/*/foo/' . 我们正在尝试使用spring集成[SFTP outbound-gateway]连接到SFTP服务器,以下载具有以下目录表达式'/ * / * / foo /'的所有文件。 unfortunately we are getting different exceptions :
不幸的是,我们得到了不同的例外:

we are using the following : 我们正在使用以下内容:
<int-sftp:outbound-gateway session-factory="sftpFactory" request-channel="download"
command="mget" command-options="-R" expression="'/*/*/foo/'" remote-file-separator="/"
local-directory-expression="'${local.dir}'+ #remoteDirectory" reply-channel="outputChannel"
auto-create-local-directory="true" />
Only simple wildcards are supported, such as /foo/*
- meaning fetch recursively from /foo
- the *
is actually not needed in this case, /foo/
will do the same thing. 仅支持简单的通配符,例如
/foo/*
-表示从/foo
递归获取-在这种情况下实际上不需要*
, /foo/
将执行相同的操作。
But, there's no way to wild-card higher level directories. 但是,无法通配更高级别的目录。
Depending on how complex your tree is, you might be able to use a custom filter instead - the filter is invoked during each recursion (where each directory is listed, filter applied, then files fetched). 根据您的树的复杂程度,您可能可以改用自定义过滤器-每次递归时都会调用该过滤器(列出每个目录,应用过滤器,然后提取文件)。
