QUESTION
I have a service I want to access using Feign client. The problem is that it requires authorization using OAuth2, password
(as said in the Authorize
page of Swagger and flow: password
is set).
In the Swagger
page of the service I can get the access to the methods by simply clicking on the Authorize
and inputing my login
and password
, choosing request body
and leaving client_id
and client_secret
fields as they were default, but how do I do that using Feign client now?
I tried following this guide but it describes how to do it with grant type client_credentials
so it didn't work for me, it was expectedly giving errors and not accesing the method of the service. I checked the api of the service just to be sure, grant type is in fact password
. When sending a request it was doing it with "Bearer null".

Answered 2022-Mar-10 at 12:10Grant type "password" would mean that your resource server sends userid and password to the authentication server (oauth 2 server). This would mean you would send data tied to an actual user of your application over the wire. This is not something you want do anymore and this grant type is deprecated.
When you say you input client id and client secret in swagger, you are actually using grant type "client credentials" and not grant type "password". The data you are sending "over the wire" identifies an application or client, hence CLIENT id and CLIENT secret.
The userid and password you are entering is not sent to the authorization server. It might be some kind of BASIC authentication you have in front of your swagger mask.
Stick to your Bealdung guide, its exactly what you want to do. Setup all the beans you can see under 4.2 and provide the needed configuration. Afterwards you should be able to autowire the configured feignclient bean and use it anywhere.
QUESTION
I'm trying to implement OAuth2 password grant type with feign client. I followed this guide (only the feign client part). I do it in the separate project (let's call it feign
) and then use it as dependency in the other project
(let's call it like this). The problem is that if I do everything like in the guide, the javax.ws.rs.core.Response
class in the project becomes different from what it was, so one method just disappers. My pom.xml
of feign
if I follow the guide fully (the source code of the guide)
