![]() Spring framework overcomes all of the above problems by providing an abstraction over the different transaction APIs, providing a consistent programming model. If I am using Hibernate, then the hibernate transaction API and JTA at application server is for global transactions. If I am using JDBC, then the transaction management API is for JDBC. So when you annotate a method with Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you're annotating. And you can provide your own, too, for things like logging. In both global and local transaction, we have to manage the transaction by ourselves. Transaction management is just one example of the behaviors that can be hooked in. With local transaction, all the transaction code is within our code. Spring Boot + Apache Camel SQL component + Transaction Management Example In this tutorial we will be implementing a Spring Boot + Apache Camel SQL Component Example for inserting and retrieving records from MySQL database. Local Transactions: Local transactions happen between the application and a singled RDBMS, such as a simple JDBC connection. This is a complex process and requires knowledge at the application server level. JTA or java transaction API is required with the support of JNDI to lookup different databases, and the transaction manager decides the commit or rollback of the distributed transaction. The transaction manager cannot sit within the application to handle it, rather it sits in the application server level. ![]() This is called distributed transaction processing. For an application transaction if any action fails then all other actions gets rolled back. Global Transactions: There can be applications (very unlikely) where the transaction can happen between different databases. In Spring Boot Transaction Management Example we had seen application transaction is a sequence of application actions that are considered as a single logical unit by the application. ![]() We call it a rollback of all the steps in the transaction if anything fails in between. Behind the scenes, an aspect takes care of creating and maintaining transactions as they are defined in each occurrence of the Transactional annotation. If one of them fails, the entire process fails. Overview Spring's Transactional annotation provides a nice declarative API to mark transactional boundaries. ![]() Here, the unit of work is money debiting from Account A and money crediting to Account B. annotation: Learn the usage of the annotation and a few caveats of it.Ī transaction is a logical unit of work that either completely succeeds or fails.Spring Transaction management: Understand Spring Transaction management in depth.Transaction management is a vast topic, hence I am dividing this article into two sections: This article will cover the Spring transaction management in detail. How to perform transaction management in Spring boot 1) In the first step the transaction is being and it will start executing the business logic. ![]()
