SpringBoot實作國際化中英文翻譯

配置IDEA

1.設定編碼為UTF-8

2.在resources目錄下創建 i18n 檔案夾 internationalization簡寫

? 在檔案夾中創建組態檔login.properties

? 再創建login_zh_CN.properties

配置不同語言的properties

en-US 英國(美國)
zh-CN 中文(簡體，中國大陸)
zh-SG 中文(簡體，新加坡)
zh-HK 中文(繁體，香港)
zh-MO 中文(繁體，澳門)
zh-TW 中文(繁體，臺灣)

IDEA同時配多語言

通過MessageSourceAutoConfiguration這個類

@Bean
public MessageSource messageSource(MessageSourceProperties properties) {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    if (StringUtils.hasText(properties.getBasename())) {
        messageSource.setBasenames(StringUtils.commaDelimitedListToStringArray(StringUtils.trimAllWhitespace(properties.getBasename())));
    }

    if (properties.getEncoding() != null) {
        messageSource.setDefaultEncoding(properties.getEncoding().name());
    }

    messageSource.setFallbackToSystemLocale(properties.isFallbackToSystemLocale());
    Duration cacheDuration = properties.getCacheDuration();
    if (cacheDuration != null) {
        messageSource.setCacheMillis(cacheDuration.toMillis());
    }

    messageSource.setAlwaysUseMessageFormat(properties.isAlwaysUseMessageFormat());
    messageSource.setUseCodeAsDefaultMessage(properties.isUseCodeAsDefaultMessage());
    return messageSource;
}

進入MessageSourceProperties 得到需要配置 message

在application.properties中配置message 這里需要配置我們默認的位置

在i18n下的login

#我們的組態檔的真實位置
spring.messages.basename=i18n.login

HTML中對鏈接進行請求引數

         <a  th:href="https://www.cnblogs.com/wakanda-forever/archive/2023/03/16/@{index.html(l='en_US')}">English</a>
         <a  th:href="https://www.cnblogs.com/wakanda-forever/archive/2023/03/16/@{index.html(l='zh_CN')}">中文</a>

參考原始碼：AcceptHeaderLocaleResolver類中的重寫方法，創建地域決議器

public class MyLocaleResolver implements LocaleResolver {

    //決議請求
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        //獲得請求中的語言引數
        String language = request.getParameter("l");

        Locale locale = Locale.getDefault();//如果沒有就使用默認的

        //如果請求的鏈接攜帶了國際化引數
        if(!StringUtils.isEmpty(language)){
            //zh_CN
            String[] split = language.split("_");
            //國家，地區
            locale  = new Locale(split[0], split[1]);
        }

        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {

    }
}

在config中通過Bean 注入

//自定義國際化組件生效
    @Bean
    public LocaleResolver localeResolver(){
        return new MyLocaleResolver();
    }
}

1.首頁配置：所有靜態資源都需要使用thymeleaf接管；
- 2.url @{}
2頁面國際化：
- 我們需要配置i18n檔案
- 我們在專案中需要進行按鍵自動切換，我們需要自定義一個組件LocaleResolver
- 記得將自己寫的組件配置到spring容器中 @Bean
- {}
