spring boot security 异常消息如何本地化？

xml配置是加上个bean就可以 ，
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">


spring boot中需要怎么配置呢？我也声明了个bean但没有效果
@Bean
MessageSource getMessageSource(){
ReloadableResourceBundleMessageSource parentMessageSource = new ReloadableResourceBundleMessageSource();
parentMessageSource.setDefaultEncoding("UTF-8");

parentMessageSource.setBasename("classpath:org/springframework/security/messages");

return parentMessageSource;
}
