@RequestMapping(value = "/category/all", method = {POST, GET})
public ListCategory all() {
    ListCategory response = new ListCategory();

    response.setListCategories(categoryDAO.selectAllCategory());
    response.setResponseStatus(1);
    //failedMessage = messageSource.getMessage("messages.customer.notActive", new Object[]{},Locale.getDefault());
    response.setResponseMessage(messageSource.getMessage("messages.agent.notAccessMenuAgent",
            new Object[]{},Locale.getDefault()));
    //activity Logging
    CommonMobileAgentUtil.activityLogging(response.getResponseStatus());

    return response;

这似乎有你要找的细节：http://www.ekiras.com/2016/01/springboot-internalization-and-i18n.html

配置：

@Bean
public LocaleResolver localeResolver() {
 SessionLocaleResolver slr = new SessionLocaleResolver();
 slr.setDefaultLocale(Locale.US); // Set default Locale as US
 return slr;
}

@Bean
public ResourceBundleMessageSource messageSource() {
 ResourceBundleMessageSource source = new ResourceBundleMessageSource();
 source.setBasenames("i18n/messages");  // name of the resource bundle 
 source.setUseCodeAsDefaultMessage(true);
 return source;
}

Controller（注意参数中的Locale）：

@RestController
public class HomeController {

   @Autowired
   private MessageSource messageSource;

   @RequestMapping("/msg")
   public String msg(@RequestHeader("Accept-Language") Locale locale){
      return messageSource.getMessage("msg",null,locale);
   }
}
