Question

我们尝试使用spring integration [SFTP outbound-gateway]连接到SFTP服务器，以使用以下目录表达式“/ * / * / foo /”下载所有文件。不幸的是，我们有不同的例外：

我们使用以下内容：

<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" />

Answer 1

仅支持简单的通配符，例如/foo/* - 意味着从/foo递归获取 - 在这种情况下实际上不需要*，/foo/将执行相同的操作的事情。

但是，没有办法通过更高级别的目录。

根据树的复杂程度，您可能可以使用自定义过滤器 - 在每次递归期间调用过滤器（列出每个目录，应用过滤器，然后获取文件）。
