带有thymeleaf国际化的Spring 4不识别来自资源属性文件的消息

Question

使用Spring 4 + thymeleaf开发我的webapp以支持国际化。我尝试了很多方法改变位置文件和配置的basename和仍然收到??标签。模板结果。下面是我的代码

@Configuration
@EnableSpringConfigured
@EnableWebMvc
@EnableScheduling
@ComponentScan(basePackages = {"com.categorybags.web.controller", "com.categorybags.persistence.services"})
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/res/**").addResourceLocations("/res/");
    }
    @Bean
    public ViewResolver viewResolver() {
        ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
        templateResolver.setCacheable(false);
        templateResolver.setPrefix("/WEB-INF/jsp/");
        templateResolver.setSuffix(".jsp");
        templateResolver.setTemplateMode("HTML5");
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver);
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setCharacterEncoding("UTF-8");
        viewResolver.setOrder(1);
        viewResolver.setTemplateEngine(templateEngine);
        return viewResolver;
    }
    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver localeResolver = new SessionLocaleResolver();
        localeResolver.setDefaultLocale(new Locale("en"));
        return localeResolver;
    }
    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("lang");
        return localeChangeInterceptor;
    }
    @Bean
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("WEB-INF/messages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }
}

属性文件位于WEB-INF下，路径为srcmainwebappWEB-INFmessages_en。

我认为我能够通过仅将ViewResolver注册到Spring而不是SpringTemplateEngine和ServletContextTemplateResolver的其他2个组件来重现您的问题。

所以我认为你应该尝试拆分你的配置一点注册这2个其他组件到弹簧容器。下面是代码:

@Bean
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setCacheable(false);
    templateResolver.setPrefix("/WEB-INF/jsp/");
    templateResolver.setSuffix(".jsp");
    templateResolver.setTemplateMode("HTML5");
    return templateResolver;
}
@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());
    return templateEngine;
}
@Bean
public ViewResolver viewResolver() {
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine());
    viewResolver.setCharacterEncoding("UTF-8");
    viewResolver.setOrder(1);
    return viewResolver;
}
