Faced with such a problem that when using in pom.xml spring-boot-starter-validation stops displaying the html page with registration. Without this, Thymeleaf works correctly. I searched through all the forums, and did not find the problem.

i know there is something terribly wrong with my understanding of how this whole annotation thing gets wired up and maps to the Valid. I've rummaged through all combinations and posts in StOv for similar exceptions, but I've clearly missed something. could someone be so kind as to point out my blunder here?
I could make validation work through js or html, but it is important for me that it is implemented through Java
advance thanks
