Spring & Spring Data JPA: Managing Transactions

Spring Boot and Spring Data JPA make the handling of transactions extremely simple. They enable you to declare your preferred transaction handling and provide seamless integration with Hibernate and JPA.

The only thing you need to do is to annotate one of your methods with @Transactional. But what does that actually do? Which method(s) should you annotate with @Transactional? And why can you set different propagation levels?

I will answer all of these questions in this video. To make that a little bit easier to understand, I will focus on local transactions. These are transactions between your application and 1 external system, e.g., your database.

Been struggling for a few days to figure out how this annotations help with our backend applications and your video made it so clear to me now. God bless you, man!

good explanation, thank you for the video

Thank you for another great video . Can you also cover the need of optimistic locking and when do we need to use that in spring data jpa .

[hyperborean]

Thank you for another great explanation. By the way why didn't you mention 'isolation' attribute?

Hi janssen,

Thanks for excellently explaining transaction management in Spring Data JPA.
Is there any resource on your blog expalining the use of @Lock and @Version please?

Thank you, a very clear video, just a question: does spring support both declarative and programmatic transaction management ?

[park]

didn't know that readonly done by not doing dirty checking! thanks

Thanks for the great video. If there are 3 different table updates. I have written them in different methods. I used @Transaction annotation for all of them but when 3rd fails, it does not rollback 1st two method transactions. How can I solve this?

[shomer]

Thanks for sharing all this knowledge. I m confused on why we need to add @Transaction without customizing it in the service if it's by default in repository.

[jaideeph]

Sometimes the rollback for Exception.class won't work when we use multiple entities for multiple tables and make more than one CRUD operations in a service class . Any suggestions for this .. ??

[ketantank]

Sir your video are very informative..but one question arises, How to avoid cocurrent read and insert if your java application is deployed on different servers Or jvm and connect with one db how transaction work in that scenario..

[christophe_agoero]

It is possible to add the annotation @Transactional on the class. On each of my services I put on the class level @Transactional(readOnly = true) like that by default I do not open a transaction and if my method modify the base then I add an @Transactional on the méthode.
