How To Use WebFlux with Spring Boot
Using WebFlux with Spring Boot is straightforward and may not require changes when moving from Spring MVC. We will still use the same set of annotations like RestController and RequestMapping, to name a few. However, we use WebFlux to tap
Create Email in Spring Boot using Apache FreeMarker
Suppose our application needs to email in text or HTML format; how can we do that without changing a lot of codes? We use templates! Spring Boot makes it a lot easier working with Apache FreeMarker with FreeMarker Starter POMs.
KrakenD API Gateway – Quick Start With Docker
