MyFeignConfiguration.java

@Configuration
public class MyFeignConfiguration {
    // TODO: generify MyApiClient 
    @Bean
    public <T extends MyApiClient.Api> T apiClient(final Class<T> api) {
        ...
        
        // How to generify MyApiClient ?
        ApiClient client = new MyApiClient();
        
        ...
    }
    
    // TODO: generify MyApiClient 
    @Bean
    public <T extends MyApiClient.Api> ErrorDecoder getGenericErrorDecoder(final Class<T> api) {
        return AnnotationErrorDecoder
                .builderFor(api)
                .withResponseBodyDecoder(decoder)
                .build();
