MyService api = Feign.builder().client(RibbonClient.create()).target(MyService.class, "https://myAppProd");

yangguang001 commented 6 years ago 
public DynamicIntProperty(String propName, int defaultValue) {
        super(propName, Integer.valueOf(defaultValue));
    }

should be

public DynamicIntProperty(String propName, int defaultValue) {
        public super(propName, Integer.valueOf(defaultValue));
    }

This appears to be a dependency resolution problem in your project. If you do not want to use the version of Ribbon referenced by Feign, exclude it or override it.
