Unable to upload file to azure blob container on new file creation using apache camel-CodePudding

I want to upload files created in hello directory to azure blob container. I was able to upload the exact file name within route URL. But, when i place a placeholder to read the filename it was not working.

Working:

.to("azure-storage-blob://accName/container?blobName=text.txt&operation=uploadBlockBlob&serviceClient=#serviceClient")

Not Working:

.to("azure-storage-blob://accName/container?blobName=${header.CamelFileName}&operation=uploadBlockBlob&serviceClient=#serviceClient")

Here is the code:

  @Service
    public class SftpWatcherRoute extends RouteBuilder {
    
    
      @Override
      public void configure() {
    
    
        from("file-watch:hello?events=CREATE&antInclude=**/*.txt&recursive=true")
            .routeId("fileWatch")
            .log("File Name: ${header.CamelFileName}")
            .to("direct:uploadFileToBlob")
            .end();
    
        from("direct:uploadFileToBlob")
            .routeId("uploadFile")
            .log("Azure Blob Triggered: ${header.CamelFileName}")
            .to("azure-storage-blob://accName/container?blobName=${header.CamelFileName}&operation=uploadBlockBlob&serviceClient=#serviceClient")
            .log("Blob Upload Successful")
            .log("${body}")
            .end();
    
      }
    }

I want to read the files created and upload it to azure blob container can someone help me on this ?

CodePudding user response：

Try with using the simple expression and recipient list pattern

with this it is easy to dynamically construct a URI based on a message header value

Examples:

.to("freemarker://templateHome/${body.templateName}.ftl")//It is in valid

To fix the above problem we can use either toD or recipientList.

Using toD

.toD("freemarker://templateHome/${body.templateName}.ftl")

Using the recipientList

.recipientList(simple("freemarker://templateHome/${body.templateName}.ftl"))
