Spring 4与thymeleaf国际化无法从资源属性文件中识别消息

问题内容：

使用Spring 4 + thymeleaf在我的Webapp上工作以支持国际化。我尝试了很多方法来更改位置文件和基本名称的配置，并且仍然会收到“
label.greeting _ **” 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，其路径为src \ main \ webapp \ WEB-INF \ messages_en.properties和src
\ main \ webapp \ WEB-INF \ messages_ch.properties


问题答案：

我想我是能够通过仅注册重现您的问题ViewResolver到spring，而不是属于2个其它组件SpringTemplateEngine和ServletContextTemplateResolver。

因此，我认为您应该尝试对配置进行一些拆分，以将其他两个组件注册到spring容器中。这是代码：

@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;
}
