github action or jenkins which is more demand 2025????as fresher which one learn to standout in company???????????
There is nothing like demanding in IT. Companies use these technologies as per their convenience. So you can learn any one ci/cd tech and you can able to use other ones as well, as all are same, its all about writing ci/cd scripts. Like in GitHub we create workflows, which is nothing but yml file, similiary in bamboo(bitbucket) also, we uses yml file. In jenkins, we use jenkins script. And regarding other features, all are having same features. Talking about what most companies are using, so if the project is stored in GitHub they use GitHub action, if projects stored in Bitbucket, they use Bamboo, if projects stored in GitLab, they use GitLab pipeline. And for legacy projects companies use Jenkins. Talking about what to learn to standout as a fresher, so I would recommend pick one cicd framework like GitHub action and understand how it works. How we create steps and jobs. And once you mastered it. Try other frameworks as well.
So nice ,to much knowlegable
Please make video on Abstract design pattern..
Sure.. will plan it.. meanwhile you can enjoy my design pattern playlist
Bro make a video on JWt and Oauth 2.0
Jaldi aayegi 🤞
Chandan please make a dedicated video on Resilience4j, i have an interview on Saturday it would be a good for me. Thanks
Yes, my next video or probably next to next video will be on resilience4j. But it will take time. Currently I'm busy with other stuff so don't have time to create more videos. But if you have interview scheduled for coming Saturday, maybe you can check other creators videos on RUclips. Hope that will help you 🙂 and all the best for your interview 🫂
Nice explanation
Please continue the series your explanation is very good
Lightstreamer ka viedio bna skte ho ...koi viedio nhi h youtube pe
I can try but can't commit because currently I'm busy and many other topics are lined up.. but noted that, will make a video on this in futurr
Bhaiya, Please make a video on using containers, k8s and actions together
Yes. I've planned for it. But it will take time.. currently busy with other stuffs
Oh, I got to tell you, it was perfect. Perfect! Everything, down to the last, minute details.
can you please create a video and explain how to implement shared DB and separate Schema architecture using Spring boot, Postgres, hibernate, JPA repository, migration using Liquibase
How to publish it bro…pls make a video
Video is already there for publishing it to maven central using ossrh and using GitHub. Please check the playlist
Thanks bro. Very helpful
It would be nice. If u explained in English
Crisp and to the point explanation with a great PPT. Keep doing this work. All The Best!
Thank you ♥️
you mentioned that you have taken so many interviews, please share some interview questions as well related to spring boot and microservices
Yes, I've planned that interview series. Stay tune!
Useful series, please plan to make video only on JWT and OAuth security as well. EHCache par bhi.
Could you make videos on spring security with a project which is used like in a company?
Yup!! It's on my list. Meanwhile, if you want to explore something around spring security, I already have created one video explaining the concept with an example. You can check that video in my rest APIs playlist... A full dedicated video will come soon!!
Hello, I have a doubt You are mentioning the query annotations and the sql query init explicitly but while using jpa repository we can directly use the named methods to get the data like geyEmployeeByAdress without mentioning the query explicitly right? Correct me if i am wrong
Good catch!! Yes you are partially correct. While using JPA we don't have in built methods like getEmployeeByAddress. However we only have getEmployeeById becoz Id is our primary key. But can use jpa conventions for method name like, public interface EmployeeRepository extends JpaRepository<Employee, Long> { Employee findByAddress(String address); } And also we can achieve the same using @query annotations. It's up to you. I prefer @query annotation because it gives us flexibility to modify the query and update the methods as per our need if needed
@proofofconceptcode thank you for the explaination
thank you to explain slowly and morely
Keep it up Chandan,always be happy,.
Very nicely explained
I have updated dependency in pom file and added plugin as well and mentioned liquibase properties file path and created liquibase properties and mentioned everything in liquibase properties file and changelog.sql as well but it's is not working. Getting error the database url has not been specified either as a parameter or in a properties file. Can you please help here.
Here I am using SQL server
Can you share your GitHub link? I'll check. Please share further details in email attached in description
Yes bro, please make video on spring security and input validation too for apis
Thank you so much.🙌🙌
Thank you bhaiya for the video.❤️❤️ Just one suggestion hai ki please keep the videos in a order for playlist else thodaa dikhat hota hai ki kaha se start kare is playlist ko sare videos start kar ke dekhna padta hai else creation date dekhna padta hai🙏🙏
Ok.. noted 👍
Thank you so much, more power to you from Dublin ie
So very nice vidoes,knowledgeable,good efforts by Chandan.Examplelarey
Good efforts by Chandan,very nice keep it up.
Can we handle exceptions in other methods as well using controller advice? Or it is captured only Excetptoions thrown by controller
You have to eventually throw exception from child to parent and at the end it should land on controller. Let say if you throw exception in service layer it should come to controller. And controller advice works for exception throws from all the controllers you have created in your application
I visited ur channel yesterday, really doing great work with this playlist ❤🎉, very helpful, Thanks for ur efforts😊
Thanks for your kind words ♥️
Clear your throat before making a video, It is really annoying.
Nice way of explaining ..👏🏻👏🏻
👏🏻👏🏻
Thanks 🔥
