HV000030: No validator could be found for constraint (Hibernate Validator) - spring

Question

I was following this tutorial for create a custom validation with multiple parameters, but I get the following exception when executing the #PostMapping method:
HV000030: No validator could be found for constraint 'com.crimsonlogic.anotaciones.TimeRangeConstraints' validating type 'com.crimsonlogic.model.NuevoEvento'. Check configuration for ''
it catches my attention that at the "check configuration for ''" part, does not tell me any kind of information.
NuevoEvento class:
#TimeRangeConstraints.List({
#TimeRangeConstraints(
fechaEvento="fechaEvento",
horaInicio="horaInicio",
horaCulminacion="horaCulminacion"
)
})
public class NuevoEvento {
#NotNull(message="Como se llamara el evento?")
#Size(max=40, message="Titulo invalido")
private String titulo;
#NotNull(message="Seleccione un tipo.")
private String tipoEvento;
private String url;
#NotNull(message="Seleccione la fecha del evento")
private String fechaEvento;
#NotNull(message="A que hora inicia el evento?")
private String horaInicio;
#NotBlank(message="A que hora termina el evento?")
private String horaCulminacion;
#NotNull(message="Seleccione un salon.")
private int salonId;
public NuevoEvento() {}
public String getTitulo() {
return titulo;
}
public void setTitulo(String titulo) {
this.titulo = titulo;
}
public String getTipoEvento() {
return tipoEvento;
}
public void setTipoEvento(String tipoEvento) {
this.tipoEvento = tipoEvento;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getFechaEvento() {
return fechaEvento;
}
public void setFechaEvento(String fechaEvento) {
this.fechaEvento = fechaEvento;
}
public String getHoraInicio() {
return horaInicio;
}
public void setHoraInicio(String horaInicio) {
this.horaInicio = horaInicio;
}
public String getHoraCulminacion() {
return horaCulminacion;
}
public void setHoraCulminacion(String horaCulminacion) {
this.horaCulminacion = horaCulminacion;
}
public int getSalonId() {
return salonId;
}
public void setSalon(int salon) {
this.salonId = salon;
}
}
TimeRangeConstraint annotation:
#Documented
#Target({ElementType.TYPE})
#Retention(RetentionPolicy.RUNTIME)
#Constraint(validatedBy= TimeRangeValidator.class)
public #interface TimeRangeConstraints {
String fechaEvento();
String horaInicio();
String horaCulminacion();
String message() default "El rango de tiempo establecido no es valido o esta ocupado.";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
#Target({ElementType.TYPE})
#Retention(RetentionPolicy.RUNTIME)
#interface List {
TimeRangeConstraints[] value();
}
}
Anyone knows causes of this problem?

Answer 1

I found the problem.
In my TimeRangeValidator class I had the code as follows:
//HERE WAS THE PROBLEM
public class TimeRangeValidator implements ConstraintValidator<TimeRangeConstraints,String> {
//--------------------------------------------------------------------------------->
private String fechaEvento;
private String horaInicial;
private String horaFinal;
#Autowired
private UsuarioSalonRepository usuarioSalon;
#Override
public void initialize(TimeRangeConstraints constraintAnnotation) {
this.fechaEvento = constraintAnnotation.fechaEvento();
this.horaInicial = constraintAnnotation.horaInicio();
this.horaFinal = constraintAnnotation.horaCulminacion();
}
//// MORE AND MOREEE CODE....////
I had to replace the String with Object
public class TimeRangeValidator implements ConstraintValidator<TimeRangeConstraints,Object>
and the problem disappeared.
Deeper explanation for those who did not understand what happened
TimeRangeValidator takes 3 fields from the form to perform the validation logic. The value that was changed previously prevented me from taking the 3 fields of the form due to the following reason:
#Override
public boolean isValid(Object value, ConstraintValidatorContext context) {
Object dt = new BeanWrapperImpl(value).getPropertyValue(fechaEvento);
Object hInit = new BeanWrapperImpl(value).getPropertyValue(horaInicial);
Object hFin = new BeanWrapperImpl(value).getPropertyValue(horaFinal);
SimpleDateFormat form = new SimpleDateFormat("yyyy-MM-dd");
try {
Date dia = form.parse(dt.toString().replaceAll("/","-"));
return TimeUtils.detectOverlappingEvents(usuarioSalon.buscarEvento(dia),
hInit.toString().replaceAll("\\s","")+":00",
hFin.toString().replaceAll("\\s","")+":00");
} catch (ParseException e) {
e.printStackTrace();
return false;
}
With the type object I can have the ability (with the help of BeanWrapperImpl) to obtain multiple values of the form to validate them.
Normally, type String (or Integer, whatever) is used to validate a single value of the form.
