Spring boot starter data rest, @Notnull constraint not working

Question

I am trying to add @NotNull constraint into my Person object but I still can @POST a new Person with a null email. I am using Spring boot rest with MongoDB.

Answer 1

i found it better to make my own version of @NotNull annotation which validates empty string as well.

@Documented
@Constraint(validatedBy = NotEmptyValidator.class)
@Target({ElementType.METHOD, ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface NotEmpty {


    String message() default "{validator.notEmpty}";

    Class[] groups() default {};

    Class[] payload() default {};

}

public class NotEmptyValidator implements ConstraintValidator {

    @Override
    public void initialize(NotEmpty notEmpty) { }

    @Override
    public boolean isValid(Object obj, ConstraintValidatorContext cxt) {
        return obj != null && !obj.toString().trim().equals("");
    }

}
