介绍

客户端通过Accept-Language管制国际化显示。

messageSource

  • getMessage(String code, Object[] args, String defaultMessage, Locale locale)
  • getMessage(String code, Object[] args, Locale locale)
  • getMessage(MessageSourceResolvable resolvable, Locale locale)

应用

1、springboot自带国际化，不须要独自引入依赖。

2、在resource下新建 i18n/messages.properties

3、在启动配置文件减少以下内容

  • properties配置
# locale 国际化spring.messages.basename=i18n/messagesspring.messages.encoding=UTF-8
  • yml配置
# locale 国际化spring:    messages:       basename: i18n/messages       encoding: UTF-8

4、在应用的类中引入 MessageResource

@ControllerAdvicepublic class GlobalExceptionHandler {    @Autowired    private MessageSource messageSource;        private String getLocaleMessage(HttpServletRequest request, String code, Object[] msgArg) {        Locale locale = RequestContextUtils.getLocale(request);        if(locale == null){            locale = Locale.US;        }        return messageSource.getMessage(code, msgArg, locale);    }}

5、在动态类中应用

public static BaseResponse success(HttpServletRequest request, String requestId, Object object){    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();        messageSource.setCacheSeconds(-1);    messageSource.setDefaultEncoding(StandardCharsets.UTF_8.name());    messageSource.setBasenames("/i18n/messages");        Locale locale = RequestContextUtils.getLocale(request);    String code = ErrorCode.SUCCESS;    String message = messageSource.getMessage(code, null, locale);    BaseResponse res = new BaseResponse();    res.setRequestId(requestId);    res.setCode(code);    res.setMessage(message);    res.setData(object);    return res;}
