강사님, 저 유효성검사가 되지 않습니다.

강사님 저 질문이있습니다.
아래는 4개 파일 다 소스 첨부했구요.
유효검사를 작성했는데, BindingResult result 했는데도 제대로 검사가 안돼서
초과하는 범위를 써도 에러가 0 이라고 뜹니다. 한 번 체크해주세요 감사합니다.
(pom.xml에도 아래와같이 추가는 잘 하였습니다.ㅜ..  

		<!-- https://mvnrepository.com/artifact/javax.validation/validation-api -->
		<dependency>
		    <groupId>javax.validation</groupId>
		    <artifactId>validation-api</artifactId>
		    <version>2.0.1.Final</version>
		</dependency>
		
		<!-- https://mvnrepository.com/artifact/org.hibernate.validator/hibernate-validator -->
		<dependency>
		    <groupId>org.hibernate.validator</groupId>
		    <artifactId>hibernate-validator</artifactId>
		    <version>7.0.0.Final</version>
		</dependency>
