Thymeleaf + Spring（不启动） - 如何显示来自messageSource的消息 [英] Thymeleaf + Spring (not Boot) - how to show messages from messageSource

问题描述

我在使用Thymeleaf设置我的Spring MVC（不使用Boot，因为我在发现Spring Initializr之前启动它）时，无法显示来自我的资源包的消息。

I'm having trouble setting up my Spring MVC (not using Boot, because I started it prior to discovering Spring Initializr) with Thymeleaf to show messages from my resource bundle.

该应用程序的主要配置类是：

Main configuration class for the app is:

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "b.c.m.h")
public class HrmConfiguration extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver viewResolver() {
        ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
        templateResolver.setTemplateMode("HTML5");
        templateResolver.setCharacterEncoding("UTF-8");
        templateResolver.setPrefix("/WEB-INF/html/");
        templateResolver.setSuffix(".html");

        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.addDialect(new SpringSecurityDialect());
        engine.addDialect(new LayoutDialect(new GroupingStrategy()));
        engine.setTemplateResolver(templateResolver);

        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(engine);
        viewResolver.setCache(false);

        return viewResolver;
    }

    @Bean(name = "messageSource")
    public MessageSource messageSource() {

        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("/i18n/messages");
        messageSource.setFallbackToSystemLocale(false);
        messageSource.setCacheSeconds(0);
        messageSource.setDefaultEncoding("UTF-8");

        return messageSource;
    }

    @Bean(name="localeResolver")
    public LocaleResolver localeResolver(){
        SessionLocaleResolver  resolver = new SessionLocaleResolver();
        resolver.setDefaultLocale(new Locale("pt", "BR"));
        return resolver;
    } 

    @Bean
    public UrlTemplateResolver urlTemplateResolver() {
        return new UrlTemplateResolver();
    }

    // other beans and configs
}

该应用程序的一般视图是：

The general view of the application is:

且messages_pt_BR.properties文件为：

And the messages_pt_BR.properties file is:

#messages
spring.messages.basename=i18n/messages

app.name=APPLICATION NAME

但是，当我试图展示时页面上某处的 APPLICATION NAME ，其中包含：

But, when I try to show the APPLICATION NAME somewhere on the page, with this:

<p th:text="#{app.name}">app.name</p>

我只得到

??app.name_pt_BR??

我浏览了许多可能的解决方案和教程，包括：

I have browsed a number of possible solutions and tutorials, including:

我仍然无法正常工作。

浏览器和操作系统设置为locale en_US。

Browser and OS are set to locale en_US.

推荐答案

我在这个问题上找到了问题的答案：

I found the answer to my problem on this question:

Spring 4 with thymeleaf Internationalization not identify from resource properties file

基本上，解决问题的方法是分离以下 @Bean ...

Basically, what solved the issue was to separate the following @Bean ...

@Bean
public ViewResolver viewResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setPrefix("/WEB-INF/html/");
    templateResolver.setSuffix(".html");

    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.addDialect(new SpringSecurityDialect());
    engine.addDialect(new LayoutDialect(new GroupingStrategy()));
    engine.setTemplateResolver(templateResolver);

    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(engine);
    viewResolver.setCache(false);

    return viewResolver;
}

...分成三个不同的bean：

... into three distinct beans like:

@Bean
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setCacheable(false);
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setPrefix(HTML_VIEWS);
    templateResolver.setSuffix(".html");

    return templateResolver;
}

@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addDialect(new SpringSecurityDialect());
    templateEngine.addDialect(new LayoutDialect(new GroupingStrategy()));
    templateEngine.setTemplateResolver(templateResolver());

    return templateEngine;
}

@Bean
public ViewResolver viewResolver() {

    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine());
    viewResolver.setCharacterEncoding("UTF-8");
    viewResolver.setCache(false);
    viewResolver.setOrder(1);

    return viewResolver;
}

从那以后，我按照我的预期运作了。

From that, I got it working as I expected.
