Introduction

In this chapter, we will cover the integration of Vaadin with Spring and Grails frameworks.

First, we show how to add Spring into the Maven project. Then we will show how to perform some basic operations with Spring, such as security, login, accessing database, localization, and dependency injection.

In the second part, we will explore the basics of Vaadin application development inside of a Grails project. We will show how to make localization, how to access database, how to work with services, and how to add an add-on.
