In this video, I delve deep into the world of Spring annotations, breaking down the top 10 must-knows for developers. Starting with @Component, @Service, @Repository to @Controller and more, I explain their importance and usage inside a Spring application. The video aims to equip developers with the know-how of annotations like @Autowired, @Value, @Configuration, @Bean, and @Transactional that enhance the development process. Also ranked are the @RestController, Request Mapping Family, and most importantly the @SpringBootApplication. Join me as we explore these critical elements of Spring and unravel how they impact your code, development process, and overall application performance making your coding cleaner, easier to read, and maintain.

A note on @Autowired since this is coming up a lot. Yes, constructor injection (and NOT using annotation-based wiring) is the recommended approach if it works for you.
But @Autowired is still an important annotation to learn about because of two things - First, it gives you more control with things like qualifiers in scenarios where construction injection doesn't work. Second, there is a good chance you WILL see it in the code and you should know what it does.

I have around 10 years of experience in The IT Industry - mostly as a Software Web Developer. Many years ago - I guess around 2010 or 2011 approx. - I decided to learn Spring Framework. And yours was the first channel I subscribed to and watched ALL of your videos on Spring framework. You introduced me to the world of Spring Framework, And I will always be thankful to you for that! I still follow your channel - mainly to revise my concepts. Thank you for the awesome work you have been doing since more than a decade! 🙌🙏💫

Great to have all these most important spring annotations in one video perfectly precise and concisely explained. Thank you for all your efforts and videos. All are just great.

Quality content, as usual. Here are a few annotations in my opinion that could be frequently used:
@Qualifier - Specifies the bean to be injected when multiple beans of the same type are present
@Primary - Indicates that a bean should be given precedence when multiple beans of the same type are present
@EnableCaching - Enables Spring's annotation-driven caching capability (Application.java)
@Cacheable - Indicates that a method's result should be cached
@EnableAsync - Enables Spring's asynchronous method execution capability (Application.java)
@Async - Indicates that a method should be executed asynchronously
@Scheduled - Specifies methods to be executed on a regular schedule for cron jobs

I leart the spring from you long back in 2011. You have been the only teacher for me for a long time. I love you.

[leithold]

Knew all these, but hearing you explain it solidifies it and fills in gaps in my knowledge. Thanks so much!

[venkatasandeepgurram]

Greatly explained koushik . Even though i used all these annotations before i got to know more about them . Thanks for the videos .

[er.sahilmd]

Wow i am so happy to see Koushik being back with some knowledge sharing again

[ramonwest]

Great video! I’m back in the job market and taking time to audit my knowledge base, this was very affirming and helped clarify a few unknowns.

Wow this is great. This is what I was telling you last week. Thank you so much for getting this done. Please do consider doing YouTube shorts for most used annotations in the spring framework which you couldn't cover in this video.
