validator-example

A Spring Boot 2 application that demonstrates how to customize the Hibernate Validator.

Specifically, this example configures a ClockProvider, and sets the hibernate.validator.temporal_validation_tolerance global property.

This allows for a margin of error, due to out of sync clocks for example, when validating temporal constraints such as:

javax.validation.constraints.Past
javax.validation.constraints.PastOrPresent
javax.validation.constraints.Future
javax.validation.constraints.FutureOrPresent

Running the tests

This example also demonstrates how to mock a ClockProvider during unit testing. Use the following command line to execute the tests:

./gradlew clean test
