Overview of this book

Spring MVC helps you build flexible and loosely coupled web applications. The Spring MVC Framework is architected and designed in such a way that every piece of logic and functionality is highly configurable. Also, Spring can integrate effortlessly with other popular web frameworks such as Struts, WebWork, Java Server Faces, and Tapestry. The book progressively teaches you to configure the Spring development environment, architecture, controllers, libraries, and more before moving on to developing a full web application. It begins with an introduction to the Spring development environment and architecture so you're familiar with the know-hows. From here, we move on to controllers, views, validations, Spring Tag libraries, and more. Finally, we integrate it all together to develop a web application. You'll also get to grips with testing applications for reliability.

Chapter 8. Validate Your Products with a Validator

One of the most commonly expected behaviors of any web application is that it should validate user data. Every time a user submits data into our web application, it needs to be validated. This is to prevent security attacks, wrong data, or simple user errors. We don't have control over what the user may type while submitting data into our web application. For example, they may type some text instead of a date, they may forget to fill a mandatory field, or suppose we used 12-character lengths for a field in the database and the user entered 15-character length data, then the data cannot be saved in the database. Similarly, there are lots of ways a user can feed incorrect data into our web application. If we accept those values as valid, then it will create errors and bugs when we process such inputs. This chapter will explain the basics of setting up validation with Spring MVC.
