Validation error: "Cannot find validator 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:
Cannot find validator for type: java.lang.Integer

Here is my code:

Answer 1

It looks like this is what I came across before, this post helped me.

Configure error messages for failures during binding. See this link for more information on creating a MessageSource bean in the application context and creating the messages.properties resource package:

Answer 2

According to the javadoc of NotEmpty Integer is not a valid type for validation. This is for strings and collections. If you just want to make sure that the integer has some value, javax.validation.constraints.NotNull is all you need.

public @interface NotEmpty

It is argued that an annotated string, collection, map, or array is not null or empty.

Answer 3

You can add a hibernation validator dependency to provide a validator

 <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>6.0.12.Final</version> </dependency> 

Answer 4

When asked a question, just use @Min (1) instead of @size for integer fields and it will work.
