java - Spring Integration SFTP出站网关mget -R问题

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。不幸的是，我们得到了不同的例外：

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" />

最佳答案

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。

但是，无法通配更高级别的目录。

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）。
