Data Integrity

In the previous articles, we explored how to start or join transactions (propagation) and how to handle concurrency (isolation). However, even if you have those aspects covered, you still need to decide what happens when exceptions occur: What if you need to roll back on a checked exception like IOException? Or what if you want…

In the previous article, we explored the various propagation modes (REQUIRES_NEW, NOT_SUPPORTED, etc.), showing how different pieces of your application can start new transactions or share existing ones. However, even if you’ve got propagation nailed down, that alone won’t guarantee your data remains consistent when multiple users or services hit the database at the same…

In our previous discussions, we discovered how @Transactional can automatically handle commits and rollbacks in Spring. Yet, real-world scenarios raise questions like: That’s exactly where transaction propagation steps in. This article explores the different propagation modes and how each fits common situations in everyday development. 1) What Is Transaction Propagation? Propagation in Spring determines how…

You’ve seen how @Transactional allows Spring to automatically manage commits and rollbacks, freeing you from having to code transaction boundaries by hand. But once you start using it, a question arises: Should you declare @Transactional at the class level or the method level? This article dives into the pros, cons, and potential pitfalls of each…

In the previous article (Part 3), we traced how Java’s transaction management evolved from JDBC → EJB → Spring (programmatic style): Here in Part 4, we examine Spring’s further breakthrough: declarative transactions—a way to simply annotate a method with @Transactional and let the framework handle all transaction details, without the overhead of an application server….
