What is the Spring framework really all about?

[@kumar29nov]

Nice video, thanks, but I’ve always wondered why you need an instance? Why not just static methods for services?

[@Java.Brains]

Good question! Static methods are difficult to test and mock, so are generally avoided.

[@jpnoyola]

That works for classes that only provide services, but not for classes that create data transfer objects; you can't save multiple sets of data in one set of class variables. For the same reason, if a class needs to save multiple configurations, it needs to produce configurable objects. I hope that helps.

[@Thepankaz1]

@@jpnoyola whats the problem when static methods creat DTO

[@srk96]

static concept destroys object oriented programming. that's why scala and kotlin don't use static but singleton object.

[@shankhamandal9707]

Overriding is not possible

1. Managing objects & Lifecycle dependencies by providing Application context and dependency injection 2. Data access 3. Spring MVC

[@djanupamdas]

Please do not stop creating Videos. Your teaching is very very useful for us.

[@Bharat60425]

Oh Man!!!! just in a matter of few minutes I actually understood the significance of Singleton approach. As the example you gave in regards to AccountService Class. I used to ask many people about actual real-time use of Singleton pattern in java application. I got the essence today. you are just marvelous. Thanks! a lot.

[@progtom7585]

Finally... someone who ACTUALLY explains what spring does in a simple way!! Thanks heaps!

[@cafeta]

Love Spring framework, I think I have not seen a more simple and clean explanation like this, Thanks for this video.

[@whimsicalkins5585]

This was the thing I needed for the entire day ! What spring is actually about ? I got a very intuitive answer from this video. Thanks so much.

[@rahulkala2885]

Thank you Sir by studying your tutorials of Rest and Spring I cracked the Java interviews of many companies. Thank You very much May God Bless You

[@wilfredomendez3450]

Every time a have a question on any Java topic, I come to your channel looking for answers, thanks a lot.

[@carsonmiller2701]

I would also like to request that you make a video or a series of videos on spring security. Your tutorials are much better than other ones online and I think that would be a good topic

[@zeeshannaqvi4091]

This is such a great video. Thank you for all the effort you put into making these.

[@godnonamesleft]

This was presented very well. My work has been trying to get me to learn spring but the material they gave me was a muddled mess. You have given me a much better conceptual understanding.

[@VOGTLANDOUTDOORS]

YOU are one of the BEST PRESENTERS I've come across since Al Gore INVENTED The Internet ;-) --- KEEP MAKING VIDEOS !!!

[@parvezahmed5287]

[@ashvinshetty5582]

Really good video with clear explanations!

[@jnfrle]

A friend recommended your spring playlist and they've been very helpful in filling in the knowledge gap while I use SpringBoot and SpringSecurity at a java web dev boot camp. Thank so much! - Jen

[@jaydeep5112]

I like the way how u deal with concepts in a practical manner. I'm not even watched of the video yet, and I couldn't resist hitting like button for the way u explained the dependency injection without actually using the term itself... please don't stop making videos bro.. thanks a ton!

[@martinhoransky1816]

Absolutely amazing video. Im looking forward to watch others !

[@zilenthunderz]

You're the only one who can explain Spring framework well

[@daleprather3026]

Excellent explanation. One of the clearest. Thanks!

[@daniellemizrachi8166]

I just found your channel today and your videos/explanations are some of the best I have seen! Very excited about it :)

[@thomasmunguya2207]

Awesome video. I was told to learn spring MVC by somebody but I never really understood what its all about and why I needed it in the first place. This video has made everything very clear now!

[@adnanhossain8795]

This was a treat to the eye and mind

[@mBaron29]

Excellent introduction to the Spring framework!

[@ericfricke4512]

Great teacher. Thanks for sharing your knowledge and teaching talent!

[@jiajianhwa4776]

Great job sir. Appreciate your good work. 👏 Been trying to understand spring and by far this is the best explanation.

[@abalgaebroccoli2323]

I owe so much of my knowledge and understanding to you, thank you.

[@chrisnorahloftin]

Hi asmaa can we study together im looking for few study prtners

Thanks very much! Your old video just helped me understand what I'm learning exactly at school.

[@Eiston14]

Very nice! Easy to understand the basic concept... Cheers!

I gave you a thumb up when I red to dependency injection... first video to explain greatly

[@camilovasquez8530]

Thank you, a very easy and positive way of reaching out when you want to learn something new, very good! Please continue with it!

[@Raja-lz3dl]

Apart from learning the content, i think one should learn how to really express and break down a concept and explain it like you do. I have never seen a spring explanation that doesnt bring in the jargons of DI, IOC until as late as 7th minute, exactly what i was looking for. That really helped thanks.

[@satyaprakashsahoo7772]

Your way of presentation is hats off..

[@RafaelDuarte]

Thank you a lot! I'm starting to learn Spring Boot but i wanted to get a clear image on what Spring is all about.

[@amritraj2303]

Koushik.. really a great admirer of your tutorials.Could you please videos on Spring Security especially OAuth2.0 and JWT.

I think you're slowly making me not have java with your simple explanation. You've just summed up a 4h lecture in a much more memorable and useful way.

Thank you. short but informative

[@devendrak353]

Please make video on spring security and server side data validation

[@blasttrash]

I second this. Spring Security I feel is one of the most complicated modules in Spring Framework which has less tutorials online. It would be great to have a good series of tutorials that talk about this in depth including how to connect with various datastores like sql, nosql, ldap, active directory etc. Also various protocols like basic auth, oauth2, open id connect etc.
