Question

我尝试配置我的项目以支持国际化。

我根据最近使用的JSP配置编写了简单的配置。

import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.core.env.Environment;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.view.mustache.java.LocalizationMessageInterceptor;

import javax.inject.Inject;
import java.util.Locale;

@Configuration
public class AppConfig extends WebMvcConfigurerAdapter {

    @Inject
    private Environment environment;


    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = new String[]{
            "classpath:/resources/",
            "classpath:/static/",
            "classpath:/public/"
    };

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
    }

    /* Internationalization beans */

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

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor(){
        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("language");

        return localeChangeInterceptor;
    }

    @Bean(name = "localeResolver")
    public LocaleResolver getLocaleResolver(){
        CookieLocaleResolver localeResolver = new CookieLocaleResolver();
        localeResolver.setDefaultLocale(new Locale(environment.getProperty("system.default.language")));

        return localeResolver;
    }

    @Bean
    public MessageSource messageSource() {
        final ReloadableResourceBundleMessageSource ret = new ReloadableResourceBundleMessageSource();
        ret.setBasename("classpath:translations");
        ret.setDefaultEncoding("UTF-8");
        ret.setUseCodeAsDefaultMessage(true);

        return ret;
    }

    @Bean
    @Inject
    public LocalizationMessageInterceptor getLocalizationMessageInterceptor(MessageSource messageSource, LocaleResolver localeResolver) {
        LocalizationMessageInterceptor lmi = new LocalizationMessageInterceptor();
        lmi.setLocaleResolver(localeResolver);
        lmi.setMessageSource(messageSource);
        return lmi;
    }

}

在html文件中，我无法访问翻译值。

${app.name}

未解决，

{{app.name}}

导致异常

No method or field with name 'app'

翻译文件放在资源目录下，默认语言设置为：

system.default.language=en

修改的pom.xml

Spring Boot 1.4.0.RELEASE

Answer 1

我做了一些不必要的配置。简要总结为4分。

<强> AppConfig.java

@Configuration
public class AppConfig extends WebMvcConfigurerAdapter {

    @Inject
    private Environment environment;

    @Inject
    private MessageSource messageSource;

    /* Internationalization beans */

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

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor(){
        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("language");

        return localeChangeInterceptor;
    }


    @Bean(name = "localeResolver")
    public LocaleResolver getLocaleResolver(){
        CookieLocaleResolver localeResolver = new CookieLocaleResolver();
        localeResolver.setDefaultLocale(new Locale(environment.getProperty("system.default.language")));

        return localeResolver;
    }

    @Bean
    public LocalizationMessageInterceptor getLocalizationMessageInterceptor() {
        LocalizationMessageInterceptor lmi = new LocalizationMessageInterceptor();
        lmi.setLocaleResolver(getLocaleResolver());
        lmi.setMessageSource(messageSource);
        return lmi;

    }
}

作为@M。 Deinum说MessageSource和资源配置由初学者完成，所以我们不需要它。

<强>的pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mustache</artifactId>
    </dependency>
    <dependency>
        <groupId>com.github.sps.mustache</groupId>
        <artifactId>mustache-spring-view</artifactId>
        <version>1.3</version>
    </dependency>

由于org.springframework.web.servlet.view.mustache.jmustache.LocalizationMessageInterceptor。

<强> message.properties 对于默认的locale（en）文件，message.properties是必需的。对于不同的区域设置文件，使用了message_LOCALE.properties。

这些文件应放在资源/.

HTML文件 可以使用带符号
在HTML文件中访问消息值
```
   {{#i18n}}message-key{{/i18n}} 
```
