Validation in Spring Boot

In this Spring Boot tutorial we will see how to implement validation for the incoming requests and how to create custom validation constraint.
The source code of this tutorial is here https://github.com/basarbk/spring-validation

We will check the built in constraints like @NotNull, @Size, @Email of bean validation. Also we will create our own constraint, @UniqueEmail which would be rejecting the request for signup if another user is already registered with that email address.
