Would be nice to have an example for OAuth2Token to feign client.

[@raamch]

Great and simple explanation.

How we can use autowire for quizinterface because it is an interface , In java we can't create the object for an interface right?

[@yuuta-8506]

Yes, in Java it is not possible to create an instance of an Interface, but Spring Boot uses Dependency Injection technique to create and manage Beans using Spring Context. When using Autowired (or Constructor Injection), Spring automatically injects those Beans. and FeignClient is also one of them, similar to @Component, @Service,... Normally Spring Context will try to find classes that implement interfaces if those Annotations are marked on the interface. It's possible that FeignClient will create its implementation class(s) at runtime.

[@karthiksvraja]

Hi, I faced one error. For the Feign Client interface, the bean is not created. I used SB 3.2.3 version. For trail, I change the interface to class with commented @FeignClient line then bean is created. Can you help me

[@manassharma7698]

You can create it's bean in your main class so it will created at the time of the startup of the application and you won't face that error.
