1、编写LocaleResolver实现类

import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.List;
import java.util.Locale;

/**

 *
 * 自定义解析器，解析http请求中的language信息
 */
public class DataVizLocalResolver extends AcceptHeaderLocaleResolver implements WebMvcConfigurer {
    List<Locale> LOCALES = Arrays.asList(
            new Locale("en"),
            new Locale("zh"));

    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        String headerLang = request.getHeader("Accept-Language");
        return headerLang == null || headerLang.isEmpty()
                ? Locale.CHINESE
                : Locale.lookup(Locale.LanguageRange.parse(headerLang), LOCALES);
    }
}

2、配置LocalResovler 的JavaBean

    @Bean
    public LocaleResolver localeResolver(){
        return new DataVizLocalResolver();
    }

3、新建资源文件

resource/i18n目录下，新建文件：

4、Spring配置国际化资源文件路径：

5、编写工具类根据当前语言环境获取Local Message

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.MessageSource;
import org.springframework.context.i18n.LocaleContextHolder;
import org.springframework.stereotype.Component;


/**
 * Author: liubenqiang
 * Date: 2019/9/9
 *
 * 国际化工具类，用于获取code对应的值
 * */
@Component
public class MessageUtils {

    @Autowired
    private MessageSource messageSource;

    public String getLocale(String msgCode) {
        try {
            return messageSource.getMessage(msgCode, null, LocaleContextHolder.getLocale());
        } catch (Exception e) {
            return msgCode;
        }
    }

}

6、测试

Http请求头，添加Accept-Language节点即可
