项目都做完了，领导要求国际化？？？？--JAVA后端篇

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{//SpringUtilsMessageSource 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

import os
import re# 遍历目录及其子目录下的所有.java文件
def scan_java_files(root_dir):java_files = []for root, _, files in os.walk(root_dir):for file in files:if file.endswith('.java'):java_files.append(os.path.join(root, file))return java_files# 判断是否为注释行
def is_comment_line(line):# 抓取每行的关键词，碰到返回的就翻译，这样拼装格式的可能不会翻译，自己研究吧return ((line.count("AjaxResult.")>0 or line.count("ajaxResult.")>0 orline.strip().startswith("throw new")) and not line.count(".format") >0 and not line.count('getErrorUS')>0)def extract_outer_parentheses_parts(input_string):arrs = input_string.split("+");res = []for arr in arrs:if arr.strip().startswith('"') and arr.strip().endswith('"'):passelse:res.append(arr)return res# 扫描并翻译Java工程中的中文字符
