Spring Stuff

Makes Vaadin and Spring eternally happy together

This add-on contains classes that add some missing "glue" between Vaadin and Spring. In addition, these classes help address the "scope mismatch" between Vaadin application scope and Spring web application context scope that leads to memory leaks when a Vaadin application closes.

Some key features included are:

• A Spring application context for each Vaadin application
• Autowiring of Vaadin and non-Vaadin beans
• @VaadinConfigurable for autowire-on-construction
• Helpers for background thread interaction with Vaadin application beans
• A Spring scope that matches Vaadin application scope
• Memory-leak free Vaadin listeners on non-Vaadin event sources
• Several container and property helper classes
• Auto-generation of container properties from annotations
• Auto-generation of form fields from annotations
