You can modify @jakub-kopřiva solution to implement only authorization server with below code.

 @Configuration
 @Order(Integer.MIN_VALUE)
 public class AuthorizationServerSecurityConfiguration
    extends org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerSecurityConfiguration {

      @Autowired
      JsonToUrlEncodedAuthenticationFilter jsonFilter;

      @Override
      protected void configure(HttpSecurity httpSecurity) throws Exception {
             httpSecurity
                   .addFilterBefore(jsonFilter, ChannelProcessingFilter.class);
             super.configure(httpSecurity);
      }

}
