hibernate Validator not validating model class - spring-mvc

Question

This question has been asked a lot of times, even after going through all the solutions i wansn't able to get hibernate validator working.
Controller class:-
#RequestMapping(value={"/setReg"},method={RequestMethod.GET,RequestMethod.POST})
public ModelAndView setRegistration( #Valid #ModelAttribute("userDetails") UserDetails userDetails,BindingResult bindingResult){
logger.info("setRegistration :Entry");
if(bindingResult.hasErrors()){
logger.info("binding success");
logger.info(userDetails.getUser_first_name());
logger.info("validation not working");
}
else{
logger.info("binding failure");
}
logger.info("setRegistration :Exit");
return null;
}
servlet-context:-
<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
<context:component-scan base-package="com.xmith.services"/>
<context:component-scan base-package="com.xmith.dao"/>
<context:component-scan base-package="com.xmith.models"/>
<context:component-scan base-package="com.xmith.sweb" />
<context:annotation-config/>
<!-- Enables the Spring MVC #Controller programming model -->
<annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Resolves views selected for rendering by #Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
dependency:-
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.4.1.Final</version>
</dependency>
validation class:-
public class UserDetails {
private String user_id;
#Size(min=3,max=7,message="user first name must have max length 7")
private String user_first_name;
private String user_last_name;
private String user_age;
private String user_email;
private String user_password;
Note:-
in above code i am trying to validate "user_first_name"(min=3,max=7,message="user first name must have max length 7"), however when i enter input more than 7 it still sets "user_first_name".
output:---
