springboot 2 中的语言环境

Question

我试图在我的 spring-boot 2 应用程序中使用 I18N

首先，我在我的资源/语言环境/消息中创建一个名为“messages_pt_BR.properties”的文件：

Size.Ato.sercicos=Deve conter pelo menos 1 item

Size.atoRtdpj.servicos=Deve conter pelo menos 1 item

Size.servicos=msg1

Size=msg2

validacao_documento_obrigatorio=Documento: Pelo menos 1 precisa estar preenchido

然后我创建

@Configuration

public class LocaleConfiguration {

    @Bean

    public LocaleResolver localeResolver() {

        SessionLocaleResolver localeResolver = new SessionLocaleResolver();

        Locale.setDefault(new Locale("pt","BR")); // without this line when I try to get the locale the system return en_BR

        localeResolver.setDefaultLocale(new Locale("pt","BR"));

        return localeResolver;

    }

    @Bean

    public ReloadableResourceBundleMessageSource messageSource() {

        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();

        messageSource.setBasename("classpath:locale/messages");

        messageSource.setCacheSeconds(3600); //refresh cache once per hour

        return messageSource;

    }

}

然后我创建

@Component

public class Messages {

    @Autowired

    private MessageSource messageSource;

    public String getMessage(String id) {

        Locale locale = LocaleContextHolder.getLocale();

        return messageSource.getMessage(id,null,locale);

    }

}

所以在我的控制器中我使用：

@Autowired

Messages messages;

//in my method:

messages.getMessage("validacao_documento_obrigatorio")

当我尝试测试此返回此错误时：

org.springframework.context.NoSuchMessageException: No message found under code 'validacao_documento_obrigatorio' for locale 'pt_BR'.

并且 jpa 约束不会更改为。
