Validation error: “No validator could be found for type: java.lang.Integer”

Question

I am working on a project with Spring why do I keep getting the following error?

javax.validation.UnexpectedTypeException:
No validator could be fou

Answer 1

For this type error: UnexpectedTypeException ERROR: We are trying to use incorrect Hibernate validator annotation on any bean property. For this same issue for my Springboot project( validating type 'java.lang.Integer')

The solution that worked for me is using @NotNull for Integer.
