hibernate验证器未验证模型类

Question

这个问题已经被问了很多次了，即使是在经历了所有的解决方案之后，我也无法让hibernate validator工作。

控制器类：-

@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-上下文：-

<!-- 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>

依赖关系：-

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.4.1.Final</version>
</dependency>

验证类：-

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;

我错过了什么？

正如-JB Nizet指出的那样，我的布尔逻辑是错误的
