Webflux demo project

How to get it running

Clone this GIT project.
Make sure it is a Gradle project and Gradle is executed to load dependencies.
This project demonstrates several aspects of Spring Webflux:
- for WebClient usage the ReactiveVsClassicClientTest and its classes in package de.bsi.webflux.backend can just be used.
- for Mono and Flux demonstration the ReactiveServiceTest and ReactiveEmployeeController can also just be used.
- for reactive MongoDB interaction a running MongoDB is required. Database connection is configured in application.properties. If you have Docker installed a MongoDB container can be started like this: docker run -d -p 27017:27017 --name mongodb mongo Then classes in package de.bsi.webflux.database and the JUnit test ReactiveEmployeePersistenceControllerTest will run properly.
About GeoApiClientTest this demonstrates how to use OAuth2 secured REST APIs with Spring 5. The API which I am calling is from tmforum, so you can see how it is done, but you have to provide own endpoints and credentials in application.properties file. Here are details about the API, which I use: https://www.tmforum.org/resources/specification/tmf673-geographic-address-management-api-user-guide-v4-0-0/
Caching with Redis is done in classes inside de.bsi.webflux.cache package. You can start Redis inside a Docker container like this:
- docker run -d -p 6379:6379 redis redis-server --requirepass "geheim"
