Spring Boot + Freemarker 多語言國際化的作法
1. 在 application.properties 增加
# =============================== # Multi Language # =============================== spring.messages.basename=i18n/messages # 為了取得當前頁面的URL (get current page url) spring.freemarker.expose-spring-macro-helpers=true
2. 在 resource 目錄下建立一個目錄 i18n , 並新增三個檔
messages.properties , messages_zh_TW.properties , 內容為
label.login = 登入
messages_en_US.properties 內容為
label.login = Login
3. 建立 WebMvcConfig : MvcConfig.class
@Configuration
public class MvcConfig implements WebMvcConfigurer {
//多語系設定
@Bean(name = "localeResolver")
public LocaleResolver getLocaleResolver() {
CookieLocaleResolver resolver= new CookieLocaleResolver();
resolver.setCookieDomain("jwtLocaleCookie");
// 60 minutes
resolver.setCookieMaxAge(60*60);
return resolver;
}
//多語系設定 語系切換偵測
@Override
public void addInterceptors(InterceptorRegistry registry) {
LocaleChangeInterceptor localeInterceptor = new LocaleChangeInterceptor();
localeInterceptor.setParamName("lang");
registry.addInterceptor(localeInterceptor).addPathPatterns("/*");
}
}
4. Control file: MainController.class
@Controller
public class MainController {
@RequestMapping(value = { "/","/home" })
public String staticResource(Model model) {
return "home";
}
}
5. View: home.ftl
<#import "/spring.ftl" as spring/>
<@spring.message "label.login"/>
注意, FTL的第一行要 import "/spring.ftl" ，這樣子就可以輕鬆切換語系了
