You can add hibernate validator dependency  to provide a Validator   lt dependency gt       lt groupId gt org hibernate lt  groupId gt       lt artifactId gt hibernate-validator lt  artifactId gt       lt version gt 6 0 12 Final lt  version gt   lt  dependency gt

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

User · Answer

As stated in problem  to solve this error you MUST use correct annotations  In above problem   NotBlank or  NotEmpty annotation must be applied on any String field only   To validate long type field  use annotation  NotNull

User · Answer

As the question is asked simply use  Min 1  instead of  size on integer fields and it will work

User · Answer

As per the javadoc of NotEmpty  Integer is not a valid type for it to check   It s for Strings and collections   If you just want to make sure an Integer has some value  javax validation constraints NotNull is all you need      public  interface NotEmpty      Asserts that the annotated string    collection  map or array is not null   or empty
