It can either be applied to the method level or class level. It provides data consistency and reliability.</p> <h2> Understanding transaction management in Spring Boot using @Transactional </h2> <p>• @Transactional annotation simplifies transaction management by providing a more declarative approach.<br> • This annotation can be used at the method level or class level.<br> • Developers can focus more on the business logic aspect and the annotation takes care of the transaction management.<br> • Transactional annotation is used for managing transactions in the spring-boot application.</p> <h2> Why Do We Need Transaction Management? </h2> <p>Let's grasp the concept of transactions through the provided example, considering we are having 2 tables, offer_criteria and offer when saving offer data into the database, it is crucial to save to save both information to the database.</p> <h2> Attributes of @Transaction </h2> <p>• Propogation — defines our business logic’s transaction boundary. Spring boot manages to start and pause a transaction according to the propagation setting set.<br> • Isolation- represents how changes applied by concurrent transactions are visible to each other. Each isolation level prevents zero or more concurrency side effects on a transaction. <br> • ReadOnly- marks the transaction as read only.<br> • TimeOut- sets the time limit for the transaction.<br> • RollbackFor &amp; NoRollbackFor — Specify exceptions that trigger a rollback or do not trigger a rollback, respectively.</p> <p>Hope this article has given you more understanding about @transactional annotation and the importance of using it when dealing with more than one database call in single transaction.</p> <p>Thanks for reading, kindly give like and follow for more articles.</p> java
