I have the following Document entity:
import io.jooby.FileUpload;
public class Document {
private String name;
private FileUpload file;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public FileUpload getFile() {
return file;
}
public void setFile(FileUpload file) {
this.file = file;
}
}Controller:
import io.jooby.annotations.Consumes;
import io.jooby.annotations.FormParam;
import io.jooby.annotations.POST;
import io.jooby.annotations.Path;
@Path("/")
public class Controller {
@POST("/documents")
@Consumes("multipart/form-data")
public void uploadTest(@FormParam Document document) {
System.out.println("name: " + document.getName());
System.out.println("file: " + document.getFile().getFileName());
}
}I try to upload the form:
curl --request POST 'localhost:8080/documents' --form 'name="My Document"' --form file=@"any-file-here"
And in logs I have an error:
name: My Document

The name field is set correctly but the file is missing. A workaround I see is to use an 'all-args-constructor'
