Test.java
package com.sample.test;

import java.util.Set;

import javax.validation.*;
import javax.validation.ValidatorFactory;

import com.sample.model.Employee;

public class Test {
private static ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
private static Validator validator = validatorFactory.getValidator();

private static void validateBean(Employee emp) {
System.out.println("************************************");
SetConstraintViolationEmployee>> validationErrors = validator.validate(emp);

if (validationErrors.size() == 0) {
System.out.println("No validation errors....");
}

for (ConstraintViolationEmployee> violation : validationErrors) {
System.out.println(violation.getPropertyPath() + "," + violation.getMessage());
}
