FFJ4 is a feature flags/toggles solution built in Java with full support and integration with Spring boot. FF4J is rich in features having: Feature Toggles, Role-Based Toggling, Strategy Based Toggling(White/Black Lists, Time Based, Expressions, even has integration with Drools), AOP-Driven Toggling, Features monitoring, Audit Trail, REST API, +20 Databases support, Properties via Spring, Archaius, commons-config or even consul and more.  FF4J has an interesting UI where we can see the toggles and switch them on or off. So today I made a simple video going through the code and also running the UI. So Let's get started!
