@Email annotation not working in springboot application

Question

I have a getMapping controller which accepts emailId and Set as input. I want to have a validation check for Non empty/blank values and email id validation, below is the sample code. @Email validation is not throwing any error for invalid input. Also if i pass " " @NotEmpty or @NotNull or @NotBlank is not throwing error.

Also @Pattern is not applied to all values in Set and custom error message is not displayed

@RestController
@RequestMapping("/test")
@Validated
public class TestController {
    
    @GetMapping("/test")
    public ReturnType method(@Email @RequestParam("email") String email, @Pattern(regexp = "", message ="")Set<String> values) 
    {
     //code..
    }

When Spring Boot finds an argument annotated with @Valid, it automatically bootstraps the default JSR 380 implementation — Hibernate Validator — and validates the argument
