我正在使用骆驼版本 2.15.2

我有一个端点

final String endpoint = "sftp://myUsername@$myHost:22/test-dir/?connectTimeout=5000&password=MySuperSecretPassword&ignoreFileNotFoundOrPermissionError=false&fileName=FABT_Index_DE.xls&delete=false&localWorkDirectory=/test-dir/

我执行以下操作从 SFTP 获取命名文件

  @Autowired
  private CamelContext camelContext;

  ...some Stuff...

  private Exchange fetchFile(final String enpoint, final long timeout) {
        final ConsumerTemplate consumer = camelContext.createConsumerTemplate();
        return consumer.receive(endpoint, timeout);
  }

当我在我的电脑（OS = windows）上启动我的应用程序时......一切都很好。该文件从 SFTP 获取。如果应用程序在另一台机器上运行，我认为测试是个好主意......所以我将我的 jar 复制到 SFTP（OS = linux）并在那里运行......（它是文件所在的同一台机器放置）

现在我得到以下异常：

谁能告诉我为什么我得到这个异常 - 而不是从 SFTP 获取文件？

我发现了以下内容：

我为端点和本地工作目录使用了相同的 String test-dir。经过一些实验，似乎对于端点定义

  • final String endpoint = "sftp://myUsername@$myHost:22/test-dir/?connect ...

这test-dir是一个相对路径。例如，此目录位于/vol/usr/home/MyTestUser/test-dir并且/vol/usr/home/myUsername/是 SFTP 用户的主目录（或您通过 ssh 登录时获得的目录） - 可以定义端点/test-dir/

但是对于选项localWorkDirectory

  • final String endpoint = " ... &localWorkDirectory=/test-dir/ ..."

似乎这test-dir是一条绝对路径。因为我尝试在 SFTP 上运行应用程序，所以我没有写入绝对目录的权限，/test-dir/所以我将此目录更改为/vol/usr/home/myUsername/MyTempDirectory/并添加选项&stepwise=false。现在它起作用了。端点现在是：

final String endpoint = "sftp://myUsername@myHost:22/test-dir/connectTimeout=5000&password=MySuperSecretPassword&ignoreFileNotFoundOrPermissionError=false&fileName=FABT_Index_DE.xls&delete=false&localWorkDirectory=/vol/usr/home/myUsername/MyTempDirectory/&stepwise=false";

也许有人可以更准确地澄清它......
