Getting NoProviderFoundException When try to implement "Hibernate Validator"

Question

I am getting "Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath." this error when try to implement the Validation for my Entity (ProductInstance)

Here is the Usage

try {
        Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
        for (ConstraintViolation<ProductInstance> violation : validator.validate(product)) {
            genActResponse.addErrorMessage(violation.getMessage());
            genActResponse.addFailure();
            return genActResponse;
        }
    } catch (Exception e) {
        throw e;
    }

Here is the Dependency in gradle.build

dependencies {
compile group: 'org.hibernate', name: 'hibernate-validator-annotation-processor', version: '6.0.2.Final'

And here is the error I am getting

2018-12-03 20:22:12,420 WebErrorHandler                     ERROR - General exception

Answer 1

You need to add Hibernate validator. Add one of the following:

For Gradle, add:

compile group: 'org.hibernate', name: 'hibernate-validator', version: '6.0.13.Final'

For Maven, add:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.13.Final</version>
</dependency>

You can adjust the version based on other dependencies versions'
