Basic transactions in Spring using TransactionProxyFactoryBean

Nerd Notes

UPDATE – Aug 29, 2011: I see that quite a few sites link to this article. Please keep in mind that I wrote this at the beginning of year 2007. While it should still be valid, more recent versions of the Spring Framework have largely simplified the approach described here and the online documentation about transaction management is far more complete, precise and straightforward than what I wrote years ago. I strongly encourage you to read the Spring documentation for the most up-to-date details.

Scenario: you have a simple stand-alone java application which accesses a single database using spring DAOs and you want to make your application’s interface transaction aware.

Now, while there’s plenty of ways to achieve this, the fool-proof, working approach is to make use of Spring’s declarative transactions and the TransactionProxyFactoryBean.

Here is an example BeanFactory configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
