从会话对象

Question

我是菜鸟，想要为春季启动应用程序进行国际化。这是我尝试过的但无法让它发挥作用：

@SpringBootApplication
public class CarriersApplication extends WebMvcConfigurerAdapter {

@Autowired WebContextHolder webContextHolder;

public static void main(String[] args) {
    SpringApplication.run(CarriersApplication.class, args);
}

@Bean
public RestTemplate createRestTemplate() {
    return new RestTemplate();
}


@Bean
public LocaleResolver localeResolver() {

    HttpSession session = webContextHolder.getSession();
    String lang = ((Merchant) session.getAttribute( "principal" )).getLanguage();

    // the code above is an attempt to get language from session object to set the 
     // default locale 
    // ex: lang = en,fr

    SessionLocaleResolver slr = new SessionLocaleResolver();
    slr.setDefaultLocale( new Locale( lang) );
    return slr;

}

@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
    lci.setParamName("lang");
    return lci;
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor( localeChangeInterceptor());
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}
}

我的问题是：当我定义localeResolver()方法时，是否有可能以这种方式从“主要”会话对象获取区域设置？

您可以从LocaleContextHolder获取语言环境：

@Bean
public LocaleResolver localeResolver() {
    Locale locale = LocaleContextHolder.getLocale();
    SessionLocaleResolver slr = new SessionLocaleResolver();
    slr.setDefaultLocale(locale);
    return slr;

}
