When working with the different flows, we looked at some of the important features of the Spring MVC Framework. These include the following:

• Loosely coupled architecture with well-defined, independent roles for each of the objects.
• Highly flexible Controller method definitions. Controller methods can have a varied range of parameters and return values. This gives flexibility to the programmer to choose the definition that meets their needs.
• Allows the reuse of domain objects as form backing objects. Reduces the need to have separate form objects.
• Built-in tag libraries (Spring, spring-form) with localization support.
• Model uses a HashMap with key-value pairs. Allows integration with multiple view technologies.
• Flexible binding. Type mismatches while binding can be handled as validation errors instead of runtime errors.
• Mock MVC Framework to unit test controllers.
