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
java
/**
* 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：
java
/**
* 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
XML
# 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
python
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 or
line.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("+");
