使用Bean组件处理骆驼消息

Question

I have a Camel route with FTP and Bean component which processes the message. This message is a file on FTP and I would like to get the filename of each file processed. I know how to get files with parameter String, but then I cannot get the filename. Thanks for the answer.

Answer 1

The Camel FTP component extends the File component, the File Component adds the following headers when consuming a file:

• CamelFileName : Name of the consumed file as a relative file path with offset from the starting directory configured on the endpoint.
• CamelFileNameOnly : Only the file name (the name with no leading paths).

You can check out the other available headers in the "File consumer only" section of the File2 documentation page .

In a bean method, you can pass a specific header as a parameter using the @Simple annotation giving it the value "header.<header name>" . For example:

public void processFile(@Body String fileContent, @Simple("header.CamelFileNameOnly") String fileName){
  // your method implementation
}
