Abstract:

When the Spring framework hit the marked, it revolutionized the way we build our applications. Dependency injection, and inversion of control became well known terms, and it is difficult to imagine how we managed without them. But there is one aspect of the Spring framework that has been fiercely discussed for a long time; What is the best approach to configuring our applications for deployment in multiple environments?

I have struggeled with this problem since my first encounter with the Spring framework, and over the years I have tried just about all the techniques there are. Some of them turned out to be bad - some of them turned out to be really bad. In this talk I will go through some of the techniques and approaches I have tried, and discuss their strengths and weaknesses.

Based on these trials and errors, I have put together a framework that aims to enhance the Spring container - enabling it to be differently configured for different target systems. I will demonstrate how you can use this framework to make your applications dramaticly easier to configure, easier to test, and less prone to malconfiguration in production and test environments.

Outline:

The ultimate goal
Configuration techniques that failed miserably
- Using your build system for resource filtering
- JNDI as configuration repository
- Commons Configuration
- The evil PropertyPlaceHolderConfigurer
Introducing the Stage Enabled Spring Contexts project
- Brief introduction to annotation based configuration in Spring
- Choosing implementation of services based on the running environment
- Increase testablility
- Configuration options
- Handling property files
Customization options
