Very common question in java interview: what is @AutoConfiguration, @SpringBootApplication, @ComponentScan.. Before this I had to always memorize what @AutoConfiguration does, tried several times to understand it, but couldn't really done justice to that. But now I know why it came to picture, now I know the source, so hopefully won't have to memorize again.. As always, thank you Shrayansh! I am sure we'll uncover many intricacies in this Springboot course!
You might not trust me, but I have written a fully fledged microservice in springboot from scratch (by referring to other microservices code in my org) and it's running in production for almost a year. But I didn't knew any internals like what is difference between spring mvc vs spring boot. Difference between certain annotations(like @component vs @service) etc but watching this video makes me curious to know more about the internals. Thanks a lot for your hard work, really enjoyed it. Will again create a new spring boot service from scratch and this time won't copy paste from other existing code and will really understand and learn it.
previously had a partial understanding about mvc, but now its clear why we are using spring boot, thanks and please continue this series and upload atleast 2 videos per week. thanks a lot
Thank you for this video. It's quite good, it goes deep enough into details and what I liked the most is that you kind of arranged the sequence of events, like a kind of chronology of the development of Java web technology. From Classic-Old Servlets, through Spring MVC, all the way to Spring Boot. Perfect. All the best bro ! 🇷🇸 🇮🇳
Really the best video for beginners who are starting to learn the spring boot. It clearly depicts the era of servlets and now why spring boot. Thank you for such videos.
I started your playlist after my friend suggested.I will watch the whole playlist and will share with friends as well. Also I will evaluate your content and give the honest feedbacks whenever required.
Thank you so much for your effort in this video! You solved my doubts around which problems solved spring boot showing concrete examples with code snippets and the old web.xml I really appreciate that because you are not only talking about theory you are showing concrete examples to explain the concepts. I am going to watch your next videos. Regards from Perú 🇵🇪
Sir .... I just a few days back completed Java.... After that everyone says learn spring boot, frameworks and all...., but when I am seeing some videos on spring boot i didn't understand actually what it is.... After I seen your first video now... I am ready to see the entire playlist and I am confident on myself I can learn spring boot
@@ConceptandCoding thanks you are doing a awesome job i have was earlier following another channel and Now I am thinking i just wasted my time over there but thanks to you shreyansh for bringing such good content i usually have the habit of scrolling throughout the mobile but while watching your channel I just put my mobile phone aside and just listened what you taught and it was very much helpful
Hey thanks for putting together this playlist! I've been really looking forward to it. Do you have any plans to create videos about microservices, gRPC, and Kafka? I think those topics would be super interesting to dive into!
Oh man till now I was thinking java might be the worst language for web development due to its verbose nature but spring boot really makes your life easier, you don’t have to worry about any dependency issue (believe me it’s the pain for node developers that’s why we keep lock version) and in short we can say spring boot is just a wrapper around spring with additional capabilities like dependency management, auto configuration and embedded server similar to what express do for node guys(I know lot of you will correct me I am just saying in terms usage terminology otherwise I know node is run time and spring is framework and both are super different) but I really like the embedded server thing even in our wrapper (express) we still need to create a server. I think I have to learn spring boot as well it looks interesting 😎🙌
Advantages of spring boot 1. Easy dependency management 2. Easy to configure. No need to create DispatcherServlet class etc. 3. Has embedded server. No need to deploy WAR to servlet container
Just one correction all the controller class are initialised early when the ioc container starts for eager initialisation. By default eager and singleton is used.
Sir thank you so much 🫶 One request please come to spring boot advance concepts like security and all faster and much in depth Again thankyou this is so much helpful GOATED lectures on spring boot 👏👌
hi shreyansh spring wont create any mock mockito framweork will take care of that mock and one more thing is here if you initialize @mock then ioc container dont touch that object to create or serve this is what my understanding and from my experience
This video content quality and delivery is really great. I just want to highlight or ask one thing I have created spring boot applications but I have not created class for DispatcherServlet in any of my services. I guess it is not mandatory, if yes. Then what specific purposes it solves?
The flow is not right (default mode, singleton) Actually the beans created when the application started. But you showed it when we send the request the second thing is creating instance :)
Its is handled through Scope. I havent covered the scope yet (singleton or not), Flow is this only, whether to create new object or not, that internal logic you can say, it will invoke method to create an instance, and if scope is not defined or its singleton, that method will itself return the same object. Hope that clarifies, any doubt pls let me know.
Hi Shreyansh, can you please make a video in hibernet , jpa and jdbc like how it's work with spring boot application, i used jpa but do not know the details like how these are working internally and what are the key features of these frameworks
@@ConceptandCoding Actually sir in your diagram it's servlet container that's why I am asking So is spring container also uses servlet container internally?
sir i have a small doubt , I don't have much knowledge of JAVA but I am well aware about C++ , and i wanted to start spring boot now , so is it necessary to learn java 1st or its ok that i know C++ so it work as the basic syntax and logic remains the same irrespective of the language. please guide me.
Hi Shrayansh, It is great work that you are doing in here, I recently bought your LLD course in Udemy. I am very interested in joining your channel too, Can you please help me with the below points. 1. If I join YT, are all courses available here, or will you publish some courses in Udemy only but not in YT? 2. Wherever the course is, are you planning to give notes to the people who are joining? Because I believe that is really important to revise concepts whenever needed. You deserve the payment in some way for sure because of the great work you do, I am just checking which would be a good thing for me. How much gap between each video can we expect for this Spring boot course and how many videos can we expect for this course roughly, Thanks :)
1. YT will always have the latest one. I am little less active on Udemy. 2. Notes i already upload in description section, if for any video, notes are not added, actually i missed those notes. thats why i could not add it.
@@ConceptandCoding Yes, But I want to know how DispatcherServlet internally manage thousand of mapping efficiently ? If you can cover in upcoming session
Great explanation!! What is the name of the architecture which we generally use in Spring Boot apps with CONTROLLER, SERVICE & REPO Layers. Is this called n tier architecture?
Sir the MOCK and the unit test part wasn't clear, like how does the Spring handles it, if I am not wrong, when test is ran, the spring container creates an instance and then injects it, how does this is not calling of method of User class. Can you please elaborate on this?
in Mock framework, we can instruct spring to create Mock object instead of creating new instance. i will cover Unit test cases in depth in later part of the series
Hi @shrayansh, when request comes to controller, why ioc container needs to create object of controller class , as the request can directly access the controller class respective methods ???
when a request comes to a controller, the IoC (Inversion of Control) container, also known as the Spring container, needs to create an object (bean) of the controller class to manage its lifecycle
You should've mentioned that@@ConceptandCoding . Is it a deliberate play of words above? Because it's grossly misleading! Good Marketing but Bad Business! I regret taking membership of your channel.
You don't need to reimburse me; rather, what you could do is, mention the specifics in the bio of the videos so that it's articulate.@@ConceptandCoding

awesome man
Question
Sir its servlet container or spring container
When it comes to speing mvc and spring boot ?
Spring MVC and Spring Boot use the Spring container.
@@ConceptandCoding
Actually sir in your diagram it's servlet container that's why I am asking
So is spring container also uses servlet container internally?
@@gauravsrivastava17 Yes thats my understanding, Spring container internally uses a servlet container for handling HTTP requests in web applications.
@@ConceptandCoding okay sir thanks
sir i have a small doubt , I don't have much knowledge of JAVA but I am well aware about C++ , and i wanted to start spring boot now , so is it necessary to learn java 1st or its ok that i know C++ so it work as the basic syntax and logic remains the same irrespective of the language. please guide me.
Spring boot is Java framework,my suggestion would be to learn Java first, you can check out Java basics to advance playlist.
@async annotations and completable futures both can be used in a same method? In springboot bhayia?????

2. Wherever the course is, are you planning to give notes to the people who are joining?
Because I believe that is really important to revise concepts whenever needed.

best videos sir , can you please share notes also
why you are miss the bean configuration spring and spring boot ? it's very important. spring manage the bean xml file but spring boot is not .

Hi Shrayansh, please suggest some projects for spring boot to add in resume.
