File to http upload file in apache camel

I've found the solution to transfer files from specific folder to HTTP API service by using 4.10.5 camel version

dependencies to import in the project:

implementation group: 'org.apache.camel', name: 'camel-http', version: '4.10.5'
implementation("org.apache.httpcomponents.core5:httpcore5:5.3.4")

Route example:

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;

import com.bh.fileservice.processors.FileProcessor;

@Component(value = "fileToHttpMultipart")
public class FileToHttpMultipart extends RouteBuilder  {

    @Override
    public void configure() throws Exception {
        from("file:C:\\tmp\\input?delay=5000&delete=true").threads(3, 4)
        .process(new FileProcessor())
        .log("Body: ${body}")
        .to("http://localhost:8081/v1/handler/camel/uploadFile?httpMethod=POST").routeId("uploadFile").end();
    }
    
}

Processor example:

import java.io.File;
import java.io.FileInputStream;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.commons.io.FileUtils;
import org.apache.hc.client5.http.entity.mime.MultipartEntityBuilder;
import org.apache.hc.core5.http.ContentType;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Component;


public class FileProcessor implements Processor {

    private static final Logger LOGGER = LogManager.getLogger(FileProcessor.class);

    @Override
    public void process(Exchange exchange) throws Exception {
        
        File file = exchange.getIn().getBody(File.class);
        
        exchange.getIn().setBody(MultipartEntityBuilder.create().addBinaryBody("file", file, ContentType.MULTIPART_FORM_DATA, file.getName()).build());                 
    }
}

**

API Service** and Multipart config example:

@Bean
MultipartConfigElement multipartConfigElement() {
 MultipartConfigFactory factory = new MultipartConfigFactory();
 factory.setMaxFileSize(DataSize.ofMegabytes(900L));
 factory.setMaxRequestSize(DataSize.ofMegabytes(900L));
 return factory.createMultipartConfig();
 }

@RequestMapping(value = "/uploadFile", method = RequestMethod.POST, consumes = { MediaType.MULTIPART_FORM_DATA_VALUE })
    @ResponseBody
    public ResponseEntity<?> uploadFile(@RequestParam("file") MultipartFile file) {
    
    try {
        String name = file.getOriginalFilename();
        long size = file.getSize();
        LOGGER.info("fileName: " +name +" file size: " + size );
        
        
    }
    catch (Exception e) {
        return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
    }

    return new ResponseEntity<>(HttpStatus.OK);
    }
