国际化问题
在这里面使用JSP来利用property文件应用的一个能显示多国语言的页面，
仅一个JSP和4个properties配置文件
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.awt.*" %>

String languageDefault = Locale.getDefault().getLanguage();
String countryDefault = Locale.getDefault().getCountry();
Locale defaultLocale = null;
String charset = null;
if (languageDefault == "en" || languageDefault.equals("en")){
defaultLocale = Locale.ENGLISH;
charset = "iso-8859-1";
}else if (countryDefault == "CN" || countryDefault.equals("CN")){
defaultLocale = Locale.SIMPLIFIED_CHINESE;
charset = "gb2312";
}else if (countryDefault == "TW" || countryDefault.equals("TW")){
defaultLocale = Locale.TRADITIONAL_CHINESE;

}else{
System.out.println("LanguageDefault not equals en.CountryDefault not equals TW or CN");
}
if (session.isNew()){
session.setAttribute("locale",defaultLocale);
session.setAttribute("charset",charset);
}else{
String language = request.getParameter("language");
if (language == null || language.equals(null)){
session.setAttribute("locale",defaultLocale);
session.setAttribute("charset",charset);
}else{
Locale locale = null;
if (language.equals("Locale.SIMPLIFIED_CHINESE") || language.equals( "Locale.SIMPLIFIED_CHINESE")){
locale = Locale.SIMPLIFIED_CHINESE;
charset = "gb2312";
}else if (language.equals( "Locale.TRADITIONAL_CHINESE") || language.equals( "Locale.TRADITIONAL_CHINESE")){
locale = Locale.TRADITIONAL_CHINESE;
charset = "big5";
}else if (language.equals( "Locale.ENGLISH") || language.equals( "Locale.ENGLISH")){
locale = Locale.ENGLISH;
charset = "iso-8859-1";
}
session.setAttribute("locale",locale);
session.setAttribute("charset",charset);
}
}
Locale locale = (Locale)session.getAttribute("locale");
ResourceBundle messagesBundle = ResourceBundle.getBundle("propertyFiles/uni_property",locale);//资源文件放在propertyFiles包下
String localeCountry = locale.getCountry();
String localeLanguage = locale.getLanguage();
System.out.println("locale:"+locale.toString());

四个资源文件如下

simplifiedChinese=SimplifiedChinese
traditionalChinese=TraditionalChinese
english=English
#uni_property_en.properties

#uni_property_zh_CN.properties
username=JSP\u5f00\u53d1\u8005

traditionalChinese=\u7e41\u4f53\u4e2d\u6587

#uni_property_zh_TW.properties

在同连接上单击会出现不同语言界面，另外需要注意的是
ResourceBundle messagesBundle = ResourceBundle.getBundle("propertyFiles/uni_property",locale);//资源文件放在propertyFiles包下
该方法查找的起始位置为默认的包，也就是没有名字的包，我们这里放属性文件放在propertyFiles包下，所以为propertyFiles/
另外在属性文件中使用的是Unicode编码，它支持互相转换，处理和显示现在世界上用不同语言写的文本。
