用properties文件实现国际化与本地化的一个小例子_本地国际化翻译,使用properties文件-优快云博客

本文介绍了一个JSP页面如何根据用户的浏览器设置或用户选择的语言来切换不同的字符集和显示相应的语言选项。通过检测用户的默认语言和地区设置，并允许用户手动选择语言，如简体中文、繁体中文和英语。

属性文件如下（英文,简体中文，繁体中文，默认）(放在包FullTextSearch下面)
MessagesBundle_en.properties
username=administrator
simplifiedChinese=SimplifiedChinese
traditionalChinese=TraditionalChinese
english=English

MessagesBundle_zh_CN.properties
username=/u7cfb/u7edf/u7ba1/u7406/u5458
simplifiedChinese=/u7b80/u4f53/u4e2d/u6587
traditionalChinese=/u7e41/u4f53/u4e2d/u6587
english=/u82f1/u6587

MessagesBundle_zh_TW.properties
username=/u7cfb/u7d71/u7ba1/u7406/u54e1
simplifiedChinese=/u7c21/u9ad4/u4e2d/u6587
traditionalChinese=/u7e41/u9ad4/u4e2d/u6587
english=/u82f1/u6587

MessagesBundle.properties
username=administrator
simplifiedChinese=SimplifiedChinese
traditionalChinese=TraditionalChinese
english=English

备注：
汉字转换为ascii码用命令：native2ascii.exe
运行/cmd
进入  原文件( messages_ZH_CN.properties )的目录
然后输入如下语句,回车
native2ascii -encoding gb2312 messages_zh_CN.properties messages_zh_CN1.properties
ok,在原文件的目录下生成了一个message_zh_CN1.properties文件,编码成功,happy!!
