Great! Please continue with Spring Boot Live Demo series. I request you to show some live demo on microservices with types.

[venkatasaikrishnak]

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.

[komalsingla]

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.

[punit]

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.

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?

[abirchaudhary]

could not able to see inserted rows in DB. But Postman showing 201 created with empty json response. Since Data is not saved in DB its not able to fetch findById() and giving 404. Need help to set up the DB where i can monitor the records

Good video. Cover all topics and for MySQL installation also show all steps how to install and connect because some new beginner won't be able to setup project

[paswini]

Great create a vedio on Exception Handling in Spring Boot

[aadiraj]

Direct fetching via Spring Data using findById()
Direct fetching via EntityManager using find()
Direct fetching via Hibernate Session.load()

In real time, which one is preferred ma'm?

[dinelikarunathilaka]

Love your videos. Helps to understand the toughest subject matters quite easily. Appreciate if you can do a tutorial on writing test cases for the above services using Junit. Keep up the good work. All the best!
