如何在springboot中实现页面的国际化

import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;

public class MyLocaleResolver implements LocaleResolver {
    //解析请求
    @Override
    public Locale resolveLocale(HttpServletRequest httpServletRequest) {
        String language = httpServletRequest.getParameter("l");
        Locale locale = Locale.getDefault(); // 如果没有获取到就使用系统默认的
        //如果请求链接不为空
        if (!StringUtils.isEmpty(language)){
            //分割请求参数
            String[] split = language.split("_");
            //国家，地区
            locale = new Locale(split[0],split[1]);
        }
        return locale;

    }

    @Override
    public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {

    }
}
