Answer 1

I had the same issue, it turned out to be caused by a controller method which I used to map all endpoints to something else ie:

@GetMapping("**")

Resolved the issue with changing the all-matching endpoint to:

@GetMapping("/dev/**")

Answer 2

My Problem got solved after adding the dependency below:

  @Bean
    public FrameworkEndpointHandlerMapping endpointHandlerMapping() {
        return new FrameworkEndpointHandlerMapping();
    }

Answer 3

The TokenEndpoint bean has a list of allowed HttpMethods. The default is now just HttpMethod.POST. Somehow calling the setAllowedRequestMethods after the TokenEndpoint bean has been created will fix this. I did this to fix it in a project:

@Configuration
public class OAuth2ProviderTokenGetAllowedBackwardsCompatible implements InitializingBean
{
    @Autowired
    private TokenEndpoint tokenEndpoint;

    @Override
    public void afterPropertiesSet() {
        tokenEndpoint.setAllowedRequestMethods(new HashSet<HttpMethod>() {{
            add(HttpMethod.GET);
            add(HttpMethod.POST);
        }});
    }
}
