Means a lot to us Man. 🙂🙂 thanks 👍👍

[@priteshbohrade8]

Very nicely explain as always😍... Plz continue this.. add security ,j unit ,central exception handling, as well as spring actuator.. this playlist single handedly can be able to get ppl all the concept cleared practically.. thank you so much..🙏🙂.

[@CodeDecode]

That's a very nice suggestion Pritesh, I will surely follow this approach if that's best for people 👍thanks 🙏

[@BaluKompalli]

Very useful. This is first time, i know how to use this responseEntity and advantages of the status types usage.

[@CodeDecode]

Thanks for writting back Balu 👍👍. It helps 🙏

[@psmondal123]

Eagerly waiting for the upcoming videos. Thank you so much for explaining the toughest topics in the easiest way.

[@CodeDecode]

You are Welcome....😊

[@punit41290]

Very informative and quick learning. There are couple of points which you should follow to make it more interesting. 1. In update you should take 200. 2. You should also implement rsql for pagination and search 3. Exception handling which you already mentioned 4. Auditing and logging... if possible take an AOP Concept as well.

[@CodeDecode]

Very nice topics. In This video we have just covered simple crud. We will slowly cover all these topics very soon in upcoming videos. Thanks for writing back to us. 👍👍

[@venkatasaikrishnak6984]

It's nice, requesting to create a video on Unit test cases for all layers like Controller, Service, Repository, etc with JUnit and Mockito. Very much needed.

[@CodeDecode]

Sure 👍👍

[@komalsingla6032]

Hello, thank you for making these videos. Please make CRUD videos for REST API using database along with Response Entity features. Also please make videos on validations provided in spring framework and how to create our own validations.

[@amarthyaseshu683]

Thanks for sharing, it's also recommended using another dto than directly using Employee(As it's an entity) in the controller I guess.

[@CodeDecode]

Yes that's true. I have said this in video that we use DTO s and not entities in real scenerios. But since it's just a CRUD, we are using entities directly. But since entities denotes real rows in DB, in real time projects, use DTOs.

[@amarthyaseshu683]

@@CodeDecodethanks, if possible can u create on spring security also jwt with Authorization!

[@CodeDecode]

Yes, we were about to, but didn't get good response on the video, so we thought it's not the priority for viewers. But thanks for letting us know that it's required, once done with multi threading part, we will restart security part

Hi, Thank you for such detailed explanation. I have a little problem related to the Auto generated id. After the rows 1and 2, the id is getting generated from 52 instead of 3. Is there a way to fix it or do I have to post manual id's instead to fix it?

[@sunilsinha6556]

How we will get user define value from multiple joins in a quary without mapping in entity it means custom data fetching using jpa repository

[@jigarthakkar5518]

Hello, good video. I was following your code and similarly doing in my eclipse. When I was inserting an entry from postman , what I observed that name value was not getting mapped with employee.name parameter when this request came to Controller. Due to this , In db records are getting inserted having name value as null. It would be good if you can let me know where I was wrong.

[@CodeDecode]

What the error that u are facing?

[@ayushdxt]

Can you please tell why do autowire the interface and not the service class?

[@CodeDecode]

That's one of the best practices. You know that we can call a method by either the class or it's parent reference. Relate it will kind of dynamic polymorphism then You will be able to understand that we are just calling child class method using parent reference. M I clear or should I explain more

[@ankitkatiyar82]

We are following Dependency Injection principle of SLOID here by providing interface reference.

Mam i have a doubt please clear .. why aren't we using @pathvariable in update .. we need to pass the ID of respective Entity to make it updated and get input only then .. operation could be performed... why are we manually doing this i.e sesrchind id in json format and then updating

[@007arek]

That method is wrong. You should have @pathvariable, and only if object doesn't exist you can crate it and return 201, otherwise you should return 200 or 204. You can check if id from the json and path are the same or use DTO.
