playing around with spring boot 2.0 webflux aka "reactive" and project-reactor

webflux playground

Note: this is just quick and dirty playground

• https://www.infoq.com/articles/reactor-by-example

findings

• springfox swagger currently does not work with webflux, since it has dependencies to mvc

  Caused by: java.lang.NoClassDefFoundError: org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerAdapter at springfox.documentation.spring.web.ObjectMapperConfigurer.postProcessBeforeInitialization(ObjectMapperConfigurer.java:45) ~[springfox-spring-web-2.6.1.jar:2.6.1]

    it requires: import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;
  

todo: try to include mvc, but factory spring boot with webflux ????

• I created a feature request: springfox/springfox#1809

gradle modules

• common: some shared code (example)
• rest-service-classic: (reactive) mvc-style restcontroller example
• rest-service: (reactive) functional-style router example
