How to customize spring security messages in spring boot 2.3.1

问题

I've defined this below bean as message source:

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

and this is content of messages.properties file under src/main/resources/i18n/ folder:

ExceptionTranslationFilter.insufficientAuthentication=A Custom message
AbstractAccessDecisionManager.accessDenied=A Custom message

Now, i expected to see A Custom message when an unauthorized user calls the rest, but get Full authentication is required to access this resource that is spring default exception message.

How can i solve this problem?
