Spring controller does not call @Valid

I know this question has been asked several times here, but I could not find the answer to help me

I'm trying to use annotation @Validon my controller, but spring doesn't seem to want to do anything with it

That's what I'm doing:

Versions:

<org.springframework-version>4.0.5.RELEASE</org.springframework-version>
<hibernate-annotations-version>3.5.6-Final</hibernate-annotations-version>

The class I want to check is:

public class myclass{

private int                 id;

@NotEmpty
@Min(20)
private String              title;

@NotEmpty
private String              description;
}

Controller Signature:

@RequestMapping(method = RequestMethod.POST)
@ResponseBody
public ServerResponse<Integer> addSomeClass(@RequestBody @Valid myclass mymy) {

I also set up

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

private @Value("${web.maxFileUploadSize}") int MAX_FILE_UPLOAD_SIZE;

public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    registry.addResourceHandler("/deployed/**").addResourceLocations("/deployed/");
}

@Bean
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver ret = new CommonsMultipartResolver();
    ret.setMaxUploadSize(MAX_FILE_UPLOAD_SIZE);
    return ret;
}

@Bean
public RequestMappingHandlerAdapter requestMappingHandlerAdapter(){
    RequestMappingHandlerAdapter requestMappingHandlerAdapter = new RequestMappingHandlerAdapter();
    List<HttpMessageConverter<?>> messageConverters = new LinkedList<>();
    messageConverters.add(new MappingJackson2HttpMessageConverter());
    requestMappingHandlerAdapter.setMessageConverters(messageConverters);
    return requestMappingHandlerAdapter;
}

@Bean(name ="validator")
public LocalValidatorFactoryBean validator(){
    return new LocalValidatorFactoryBean();
}
}

when i send this json:

{"title":"","description":""}

nothing happens and everything continues.

I can not find the answer.

UPDATE

I already had:

<hibernate-validator-version>4.3.1.Final</hibernate-validator-version>

So, I updated it to: 5.1.1and this is what I get
