File Upload Using Feign - multipart/form-data

For spring boot 2 and spring-cloud-starter-openfeign use this code:

@PostMapping(value="/upload", consumes = "multipart/form-data" )
QtiPackageBasicInfo upload(@RequestPart("package") MultipartFile package);

You need to change @RequestParam to @RequestPart in the feign client call to make it work, and also add consumes to the @PostMapping.

No, you don't. You just need to define a kind of proxy interface method, specify the content-type as: multipart/form-data and other info such as parameters required by the remote API. Here is an example:

public interface FileUploadResource {

    @RequestLine("POST /upload")
    @Headers("Content-Type: multipart/form-data")
    Response uploadFile(@Param("name") String name, @Param("file") File file);

}
