Since Spring Framework Version 4.0, there is a way to define a spring context in a groovy DSL, like the spring configuration can be done in Grails. A short description of this DSL can be found in the JavaDoc of the class GroovyBeanDefinitionReader and on the spring.io blog there is a good post that covers the DSL features.
Today I played around with the DSL, my context configuration covers a lot of the DSL feature and is shown in the listing.
If you like to use the groovy context in Spring JUnit test a ContextLoader must be defined, a simple test that uses the groovy context is show in the listing.
The whole demo project can be found on my github account here.
