Spring boot validate form

Question

I'm following this tutorial in order to validate my form, but since I'm using spring boot I wanted to avoid the mvc-dispatcher-servlet.xml file.

So instead of inserting it in the project I wrote a bean in my @Configuration class, obtaining this message:

Field validator in my.package.controller.MyController required a bean of type 'org.springframework.validation.Validator' that could not be found.
- Bean method 'resourceServerProperties' not loaded because @ConditionalOnClass did not find required class 'org.springframework.security.oauth2.common.OAuth2AccessToken'

I have tried both those beans:

    @Bean
public Validator validator() {      
    return new org.springframework.validation.beanvalidation.LocalValidatorFactoryBean();
}    

@Bean
public javax.validation.Validator localValidatorFactoryBean() {
   return new LocalValidatorFactoryBean();
}

with the same result. What I'm doing wrong?

Remove those beans. You are stating you are using Spring Boot which already configures that bean. You don't need to inject anything you only need @Valid on the method argument you want to validate. — M. Deinum

You could specify the OrderValidator as a @Component which implements org.springframework.validation.Validator, so the Validator implementation can be found and injected.
