无法从 apache camel 中的 sftp 下载文件，也没有打印失败日志

Question

我正在尝试使用 sftp 连接到 ftp 服务器，但似乎无法连接。 连接或凭据没有错误

骆驼上下文.xml

    <route>
<from id="_from1" uri="sftp://user@localhost:22/data/test/user?noop=true&amp;password=XXXXXX"/>
     <log id="_log1" message="downloading ${file:name}"/>
     <to id="_to1" uri="file:ftpclient"/>
</route>

我已经添加了依赖：

 <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-ftp</artifactId>
      </dependency>

日志如下：

任何帮助将不胜感激。

编辑：

当我将 JSCH 日志级别设置为它提供的信息时：

[ Blueprint Event Dispatcher: 1] SftpOperations                 INFO  JSCH -> Connection established

SFTP camel 采用相对于主/用户文件夹的路径，而不是绝对路径。搜索此路径“data/test/user”是否存在于 home/user 文件夹中的某个位置，这将是它从中挑选文件的位置。您始终可以在运行代码时启用调试日志记录，以便更好地了解正在发生的事情。 https://camel.apache.org/manual/latest/faq/how-do-i-enable-debug-logging.html
