For example, we can add noRollbackFor attribute to PersonValidateService. The Spring transaction management should be configured with a valid data source to perform operations against the database. What’s the solution? There are several ones. Behind the scenes, an aspect takes care of creating and maintaining transactions as they are defined in each occurrence of the Transactional annotation. Later executions during the transaction have no effect because they ought to be rolled back in the end. Overview Spring's Transactional annotation provides a nice declarative API to mark transactional boundaries. Transaction Management is an effective methodology that helps in achieving efficient and unambiguous transactions. Transactional proxy tracks it and sets on the rollback flag. Spring Boot Transaction Management + JPA Example Introduction: Transaction is a set of logical operations that needs to be performed in a definite and ordered manner. In previous tutorial - Spring Boot + JDBC Example we implemented JDBC using Spring boot with MySql database. PersonValidateService.validateName throws IllegalArgumentException. Spring Boot Declarative Transaction Management Example. That’s exactly what happened in our case. In this article, we explained the transaction support in the Spring Integration framework. If the RuntimeException throws out of the transactional proxy, Spring marks the current transaction as rollback only. Spring framework core concepts are Dependency Injection and Aspect-Oriented Programming. In this tutorial we will be understanding what is transaction management and implement them for an application developed using Spring Boot + JDBC. So, the whole request is being executed within a single transaction.Īnyway, there is a caveat. What is Spring Framework Spring is one of the most widely used Java EE frameworks. Spring Boot Declarative Transaction Management Example In previous tutorial - Spring Boot + JDBC Example we implemented JDBC using Spring boot with MySql database. And if it’s present already, the current one is supported.

It means that the new transaction is created if it’s missing. Here is the workflow for the defined addPeople method. So, when we inject the service that has any method, actually Spring puts the proxy. Skipping the complex details, the idea behind it is to wrap an object with the proxy that performs the required operations (in our case, transaction management). Internally Spring uses the aspect-oriented programming pattern. The XML declarative approach configures the transaction attributes in a Spring bean configuration file. Why did Spring roll back the transaction? Firstly, we need to understand the management approach. Declarative transaction management is the most common Spring implementation as it has the least impact on application code.
