Overview

This article documents a runnable Java example uses JavaBeans Validation annotations to externalize validation logic to a JavaBeans validation provider. The example depends on Spring Boot, but this is only because we use Spring Boot's machinery to pull starter dependencies, including Hibernate Validator, and get our runtime running. There is nothing Spring-specific that would prevent the same example working in a generic Java environment with JSR-303 support.

dependencies {
    implementation('org.springframework.boot:spring-boot-starter-validation')
}
