Custom error messages not working with Spring 3.2

I have trouble getting custom error messages to work with Spring 3.2. Here is my configs:

Config:

@Configuration
@EnableWebMvc
@EnableJpaRepositories(basePackages = {"com.."})
@EnableTransactionManagement
@ComponentScan(basePackages = {"com.."})
public class Config extends WebMvcConfigurerAdapter {

    @Bean
    public PersistenceExceptionTranslator jpaExceptionTranslator() {
        return new HibernateExceptionTranslator();
    }

    @Bean
    public FactoryBean<EntityManagerFactory> entityManagerFactory(
            DataSource ds, JpaVendorAdapter jva) {
        LocalContainerEntityManagerFactoryBean factoryBean =
                new LocalContainerEntityManagerFactoryBean();
        factoryBean.setPackagesToScan(new String[] { "com.." });
        factoryBean.setDataSource(ds);
        factoryBean.setJpaVendorAdapter(jva);
        factoryBean.afterPropertiesSet();
        return factoryBean;
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory  emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        return transactionManager;
    }

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.registerModule(new JodaModule());
        objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        return objectMapper;
    }

    @Bean
    public MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename("i18n/messages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        MappingJackson2HttpMessageConverter converter =
                new MappingJackson2HttpMessageConverter();
        converter.setObjectMapper(objectMapper());
        converters.add(converter);
    }

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

}

And here's messages_en_US.properties file:

Pattern.userdto.email=Invalid email.
Pattern=Invalid syntax.

UserDTO class:

public final class UserDTO {

    @Size(min = MIN_EMAIL_LENGTH, max = MAX_EMAIL_LENGTH)
    @Pattern(regexp = EMAIL_PATTERN)
    private String email;

    ...

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    ...
}

Validation is triggered using javax.validation.Valid annotation.

I'm expecting that this would print out "Invalid email" when the given email doesn't match the pattern, but I'm getting "Invalid syntax" message.

It started working after changing message key to:

Pattern.userDTO.email

You need to specify the key of the message to be used within the @Pattern constraint:

...
@Pattern(regexp = EMAIL_PATTERN, message = "Pattern.userdto.email")
private String email;
...

Otherwise the default key is used (which is "{javax.validation.constraints.Pattern.message}").
