duplicated mapping key - support for different content types on the same path & method

Opened this issue · 8 comments

Robbilie commented

currently when writing a controller with different methods for the same path but different content-types the resulting openapi.yml is invalid since it will generate two entries of the same method instead of reusing the same method and just adding the second content type.

example:
expected result:

openapi: 3.0.0

That should be easy to fix. But I do not have the time to do it myself right now.
If you can fix it yourself, I will be happy to accept the PR.

jskov-jyskebank-dk commented

@Robbilie This may be fixed by @bkratz 's changes in 1.1.5
If so, please close this issue. Ta!

m4h3 commented

hitting this problem with 1.1.5.
AFAIK @bkratz changes were related to expanding @Consumes/@produces for 1 method.
Here there is multiple methods, one for each content type.

bkratz commented

@Robbilie Could you provide some sample code. Since it is a difference, whether you have "different methods for the same path but different content-types" (as stated in your description) or one method for two different content-types (as also stated in your description).
For the first case, the actual result is absolutely correct, since you have one path and 2 'get' definitions with different 'operationId' representing the different methods.

Robbilie commented

"absolutely correct" in what sense? Certainly not in the sense of "valid open API yaml" :)

OK, I take back my sentence stating that the generated yaml is correct.

But the to be able to help you, could you provide some sample code of your controller.
You seem to have 2 controller methods for the path "/hello/world", one named "sayHelloV1" and one named "sayHelloV2".
Maybe this is helpful, especially the comment from Damon Sutherland.
Also have a look here.
