When working with Spring Boot applications, data validation is crucial to maintain data integrity and consistency. While Spring Boot provides robust validation mechanisms out of the box, handling Java primitive types like boolean can sometimes require special attention.
Here's a step-by-step guide on how to validate java.lang.Boolean types effectively in a Spring Boot application:
Define your model
Start by defining your model class where you'll use java.lang.Boolean:
