If tables are not creating automatically in postgres or anyother db. Without configuring spring.jpa.hibernate.ddl-auto=update,Hibernate will not automatically handle the creation or updating of database tables based on your entity classes. In the case of H2, the tables are created automatically due to Spring Boot's embedded database-friendly defaults. However, with PostgreSQL, you need to be more explicit in configuring how the schema should be managed to avoid unintended consequences in a production environment.
This playlist is very good... you are explaining the things in very good example and it's more understanding for me. playlist is going very intresting. looking ahead for more videos
Are we gonna get the details of queries in the console only when we executed them with Postman? Because currently I don't have a postman and I am executing queries from the H2 console but I couldn't see the log in console/terminal.
pw should be a random generated string with special characters. this version should be hashed and the hashed version should be stored in environment variables, you can use helm charts for this. only the app and the admin should be able to convert the hashed pw back to the original, the dev shoukd never use it. if you commit the pw or the hashed version to git, you need to change it.
Hello sir, this video is great! I have a question: In Postman, we're sending data using POST, and I can see it in the H2 console. However, when we reload the server, the data disappears, and we have to enter it again each time. Is there a way to store it permanently?
My server is not taking the value of the primary key i.e. prodId. No matter what value I put it always shows up as zero which prevents me from adding more entries. Can anyone help?
The information on adding JPA and embedded H2 to Maven is missing. The configuration of H2 in application.properties is missing. How Springboot creates the table "PRODUCT" in H2 from Hibernate is missing. The previous lectures have been great but this one is not good.

Thanks~
You have explained the entire spring data JPA like it is nothing, explained in way too simpler words.
Thank you so much. it will help me for sure.
Informative and very useful for me as a beginner. Thank you so much Navin and team

This content is pure gold
simply amazing , great video and great way of explaining things . Thanks
basics of spring data JPA boils down!!!
Learning Spring Boot is as enjoyable as diving into your favorite hobby.
Crazzzy man
how good it is
Greate tutor, love him
I'm surprised this is so much simpler than Entity Framework
what the... i actually get the topic. Too much time wasted to understand the logic and finally, beacuse of this video. Thank you
Hello Sir, Could you explain transactional and propagation- isolation? At what cases or conditions each of them to be used
Good explaination sir,,like you say u dony teach but educate the aliens

Nice explanation
Learning Spring Boot with mr. Navin Reddy is as enjoyable as diving into your favorite hobby 🤓
💯
Well Explained Sir
Enjoying series

Boom
maza aa gya
For production, how should we hide the username and password for security.
pw should be a random generated string with special characters. this version should be hashed and the hashed version should be stored in environment variables, you can use helm charts for this.
only the app and the admin should be able to convert the hashed pw back to the original, the dev shoukd never use it.
if you commit the pw or the hashed version to git, you need to change it.
What if you want to pass two object like JpaRepository
After running the program the table is not created. How do it fix it?

I also encountered this problem. What i did to solve it was to annotate my id field variable with "@JsonProperty("id")" . And it worked
