springboot项目国际化相信各位小伙伴都会，很简单，但是怎么项目都做完了，领导却要求国际化文件就很头疼了
国际化的SpringBoot代码：
第一步：创建工具类
/** * 获取i18n资源文件 * * @author bims */ public class MessageUtils { /** * 根据消息键和参数 获取消息 委托给spring messageSource * * @param code 消息键 * @param args 参数 * @return 获取国际化翻译值 */ public static String message(String code, Object... args) { MessageSource messageSource = SpringUtils.getBean(MessageSource.class); return messageSource.getMessage(code, args, LocaleContextHolder.getLocale()); } public static String message(String code, Locale locale, Object... args) { try{ //SpringUtils MessageSource messageSource = SpringUtils.getBean(MessageSource.class); if(locale==null){ locale=LocaleContextHolder.getLocale(); } return messageSource.getMessage(code, args,locale ); }catch (Exception e){ return code; } } } 对于Bean的处理在SpringUtils中是这样的：
/** * 获取类型为requiredType的对象 * * @param clz * @return * @throws org.springframework.beans.BeansException * */ public static <T> T getBean(Class<T> clz) throws BeansException { T result = (T) beanFactory.getBean(clz); return result; } 第二步：配置yml
# Spring配置 spring: # 资源信息 messages: # 国际化资源文件路径 basename: static/i18n/message,static/i18n/store,static/i18n/menu第三步：创建Python扫描工程--尽力了啊，有些实在匹配不上规则，大佬的话可以自己研究
