[@commonman8540]

[@rohanyadav7327]

Why do we need to create 2 different or more than 2 application context for spring application? Can you share any usecase of that ? 1:38:10

[@priyanshu4016]

2:14 in case of sessionscope , if i try to sent the request from curl command every time new object is creating . but from browser its working as expected

[@unnaipoloruvan98]

Bro you are awesome... Please create a playlist zero to advanced for spring / spring boot... I dont know where to start

[@praveen000singh]

1:24:44 we made the School class as an abstract class and making bean out of it. Is it possible because we cant instantiate the abstract class

[@aswinkamath1395]

Good explanation of concepts. Please come up with more Spring Framework tutorials.

[@priyasahu5295]

really awesome.God bless you always as you helping so many people by doing this... :) You are great

[@dharanivelvicky6057]

Your way of teaching is awesome

[@ramanandkumar7780]

Very nice explanation...you have covered a very important question that is asked frequently

[@rashmi-l5t]

Hi... Could you please reply to my query? I have a query at 1:55:23 The Testcontroller class is annotated with @controller annotation so it is now a singleton bean . If we use @autowired on MyBean object , then will it create only one instance of MyBean class? Spring creates singleton bean only once and if autowire is used on MyBean then will it create the MyBean object with Testcontroller only once and use the same MyBean object for different requests?

[@aneksingh4496]

wow ...great analysis ...very informative video

[@lets___explore]

Your way of teaching is best but I like that music also which makes the learing more exciting....

[@nikita-shamrai]

Great explanation, thank you!

[@sathishkumark6682]

Thank you so much Abhilash for the great video. Learned a lot from your videos.. 😇

[@rahulnambiar3181]

Thanks for all your lectures and giving us deep insight to java concepts.

[@shubhi2648]

How abstract class got instantiated..?(when we tried @lookup and made school class abstract)

[@vikrantharne9345]

at 1:23:19 u hv marked class as abstract then now that can be instantiated ?????

[@rohitsharma-xt8qe]

Awesome content and representation. Appreciate your hard work.

[@dharmasastha1150]

Hi Abhilash, It was a wonderful session ! Assignment 01: While printing out two School objects, got Proxy Object as output. Unable to find the reason behind it. Is it because the prototype bean generated as proxy by CGLib, singleton object too created by CGLib ?

[@deeproy2719]

around 01:26:00 q, I think the school class is subclassed by cglib that's why you are getting this. But the student bean injected here is a real bean and not a prototype bean. Try making the School class as final you will get error regarding subclassing not allowed. This was similar to proxyMode added in Student class, here also the proxy object was created by cglib and gave me error of i try to make it as final (complaining that sub-classing is not allowed)

[@smishra9691]

Superb finally i completed 3 hrs video within 8 hrs but feel very positive thanks sir ... please upload 2nd part of scope websocket and use of scope where to use what.. am waiting . . Lots of respect from odisha sir😊

[@handev1234]

Amazing video!!!

[@rushikeshjadhav6228]

Great content bro!🙌🏻 Thanks alot!🙏🏻

[@gennadyshevchenko7940]

Can you show pom o provide link to github? I've got an error "The matching wildcard is strict, but no declaration can be found for element 'context:annotation-config'." I don't know how to fix it.

[@umaparvathi606]

Ji sooper ji really excellent after watching your classes i love coding please update webservices and spring boot microservices

[@dhaivatpatel3208]

What is the scope of object created by a bean. I want to use a bean of an object which uses init method once and then that bean object is shared among the whole application. My init method calls s3 and imports a file. I don't want to do that on every instance.

[@SriHariChukka1210]

Worth watching 👍🙏

[@mcq2427]

Bro, Explain Microservises

[@manjunathakontham5232]

Can we create an instance for abstract component in case of prototype bean scope ?

[@Paradise-kv7fn]

How to share applicationcontext between threads?basically i am using a distributed cache and each thread would need access to a bean created at startup…but I get an illegalstate exception…the exception makes sense because the child threads dont have the application context but how to get around this problem? One way that i found was to replicate that bean in my cache’s instance but was wondering if there are any better ways to do this

[@tuberhsieh34]

Application scope object is not created until we need it, then why @Autowired not fail? Does Spring ignore @Autowired check for property that depends on application scope component class?

[@jayantagarwal6339]

thanks! Just a query- @1:06:00 if we make the Student class as "singleton", then also, will the multiple objects be given thru the proxyMode?

[@BirajaRoutNalini]

no it won't it will give one student object... but internally first proxy object will be created and that will get a real student object(this part remains same)

[@maan9011]

U super duper spring Master

[@khayalian]

Thanks for the great lecture, I'm also interested to build a custom Scope, how i can achieve it, any information could be great, Thanks.

[@sumitpatil291]

Hi Abhilash Please do post videos on spring batch.

[@lakshmie450]

Great job!!!

[@shubhi2648]

Hi sir, Can you also explain difference now between 'gang of 4 singleton' class and spring's '@applicationScope' class Thanks for awesome explanation as always. No one can do it better than you do.. !

[@sudheerbommisetti1116]

Hi Abhilash dude, When we are coding back to LOVE CALCULATOR project ? Many students are waiting for the database(spring JDBC) connection for that project. Kindly give update if possible 🙏. & Thanks a lot for the efforts.

[@sahilkaul6199]

God bless you brother

[@mohammadmutawe9783]

Thanks a lot for sharing.. 👏

[@mohdharish9834]

[@umaparvathi606]

Thanks a lot please update spring boot tutorial and web services

[@JobiJose-v8v]

Abstract classes cannot be instantiated. Then if we make the School class as Abstract, how can we create objects for the School class and it doesn't show any error here. Why?

[@drakezen]

What are some real world application of having to have multiple dispatcher servlets in one application?

[@chamanjain9843]

Hi singleton are not per jvm they are per class loader If i create my custom class loader can create multiple object

[@str6622]

waiting for realtime uses of scopes and also please explain briefly when to use dependency injection and new keyword while creating objects in realtime.

[@rahulwarule6377]

It's really helpful, tnx Abhilash 😊

[@tabishrizwan9137]

Hi abhilash, by using proxymode=scopedproxymode.TARGET_CLASS student constructor also called but using @lookup student constructor didn't call during school objection creation. could you please have a look on it.

[@vrmupparaju]

how to destroy beans if the scope is prototype??

[@yurii2713]

Hi! Thank you for the video. One more thing about your microphone, sometimes it is to loud to hear you, sometimes is too quiet. Just want you to know it

[@neerajchavan9760]

On a tight schedule, Sudheer. Looking forward to post soon.

[@chinthanathennakoon6065]

This is great!!! If I make Student class as final, CGLIB giving error that Student class cannot be subclassed :D :D D

[@a.s.raghuwanshi7028]

Sir excellent 👍👍👍❤️❤️❤️ love u sir

[@devidasdixit3988]

Please get video java 8 with example

[@chamanjain9843]

Also, we can create multiple Spring singleton scope beans of the same class, just with different names, because they are stored in a ConcurrentHashMap with the name, and each time you access them by name, you will get the same object.

[@mikhailpalagashvili5693]

Hey can u please do spring boot

[@anudeepgrandhi4988]

[@priyasharma-ss5fb]
