Spring ultimate basics: What are Spring Beans and what is the Spring Container?

Рет қаралды 180,528

2 жыл бұрын

Before you start with Spring it is a must have that you understand what Spring beans are. In my opinion this is explained in a too complicated way in most resources out there. I really aim to make it as simple as possible.
In short:
Spring bean: an instance of a class managed by the Spring Container
Spring (IoC) Container: the core part of Spring that is responsible for managing all the beans
In this video I will explain that (after a general introduction to Spring) and I will show you a code demo to show you how and what Spring beans get instantiated.

I wish you had continued, or for you to continue, making Spring tutorials. This one is, I believe, the best on the platform on the topic of Spring Boot and beans. If you have the time and you still want to do it ofc, you will quickly consistently rank 100k to 200k views a video. It is perhaps less than if you were tackling OOP or basic topics, as Spring is more of an enterprise tech and so has a relatively smaller size audience, but the big thing is that there is a real lack of quality Spring video tutorials. You will quickly reap in the benefits! Again, thank you for the great video! Well done!

Please please please keep this level of "explaining for dummies" and keep making Spring Boot tutorials. I'd love to learn from you more about other very common Spring Boot annotations as well as some very simple examples explained regarding securing a rest api, connecting databases, perhaps cover a very simple example of jwt token exchange with spring boot...learning from you will be most helpful.

@@BrightBoost I’ve seen alot of basic spring boot projects that span 30 mins to 3 hours. Some with micro services. Many don’t explain in detail what’s actually happening. It’s not hard to make the project but they don’t go into detail what all is happening. Like they just write pom.xml or application properties and give basic statements. A simple explanation that is easy to forget if we don’t understand what’s happening under the hood. What is hibernate and why we need it. How resttemplate works or Jpa repository. I mean I understand it (I think) but your way of showing it, is much better. Or how configuration works etc. Hoping you make a full micro services playlist
