springboot如何實現中英文變化

html: <a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>

<a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>

controller:

@RequestMapping({"/","index.html"})

public String index(){

   return "index";

}

重寫LocaleResolver類

public class MylocalResolver implements LocaleResolver {

[@Override](https://my.oschina.net/u/1162528)
public Locale resolveLocale(HttpServletRequest request) {
    String l = request.getParameter("l");
    System.out.println(l);
	//默認的請求頭
    Locale local=Locale.getDefault();
    if(!StringUtils.isEmpty(l)){
      String split[] =l.split("_");
        System.out.println(split[0]);
     local = new Locale(split[0],split[1]);
    }

    return local;
}

[@Override](https://my.oschina.net/u/1162528)
public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {

}

//注入到容器中 @Configuration

public class myConfig extends WebMvcConfigurerAdapter {

@Bean

public LocaleResolver localeResolver(){

    return new MylocalResolver();
}

}
