Injecting the validator object

Recalling the first approach, and rather than programmatically creating the validator object by creating a ValidatorFactory using the Validation class and so on, you can simply inject the Validator object as a dependency using the CDI, as shown in the following example:

@RequestScoped 
public class MovieBean { 
 
    @PersistenceContext(name = "jpa-examplesPU") 
    private EntityManager entityManager; 
    @Inject 
    private Validator validator; 
 
    public void validateMovie() { 
 
        Movie movie = new Movie(); 
 
        Set<ConstraintViolation<Movie>> violations = validator.validate(movie); 
        for (ConstraintViolation<Movie> violation : violations) { 
            System.out.println(violation.getPropertyPath()); 
            System.out.println(violation.getMessage()); 
        } 
    } 
} 

As you see, the validator object is injected as a dependency rather than having to create it with many lines of code. There will be cases...
