Best video on this topic till date, big thanks to you, request you to please make video on internals of spring-boot as well, like @EnableAutoConfiguration, or why do we need a main method in a spring-boot-app, please if you can, will be very helpful for beginners
nice explanation dude... can you plz do a example for flattening concept for below collection Map map=new HashMap(); to do different operations on Employee object
