SpringSource recently released version 3.2.1 of the Spring framework. I switched from 3.2.0 and found my Maven builds were failing. It seems some of the dependencies between Spring modules/projects has changed.
I had to make explicit mention of the spring-web and spring-jdbc projects. spring-web has the RequestMethod and RequestMapping classes I needed and spring-jdbc had some DataSource classes.
If you are going to switch to 3.2.1-RELEASE from an earlier version you might want to dump out the dependencies first just to make spotting the missing ones easier.
mvn dependency:tree
