1.格式化货币

世界上许多国家都有不同的货币格式和数字格式惯例。针对特定的本地化环境正确地格式化和显示货币是本地化的一个重要部分。

%26lt;/head%26gt;

%26lt;h3%26gt;English, USA%26lt;/h3%26gt;
%26lt;fmt:setLocale value=en_US /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;French, France%26lt;/h3%26gt;
%26lt;fmt:setLocale value=fr_FR /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;fmt:setLocale value=ja_JP /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Korean, Korea%26lt;/h3%26gt;
%26lt;fmt:setLocale value=ko_KR /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Spanish, Spain%26lt;/h3%26gt;
%26lt;fmt:setLocale value=es_ES /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Arabic, Egypt%26lt;/h3%26gt;
%26lt;fmt:setLocale value=ar_EG /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Using Local Numeric Formatting for Different Currency%26lt;/h3%26gt;
%26lt;h4%26gt;English, Great Britan%26lt;/h4%26gt;
%26lt;fmt:setLocale value=en_GB /%26gt;
%26lt;fmt:formatNumber type=currency value=80000 /%26gt;%26lt;br/%26gt;
%26lt;fmt:formatNumber type=currency value=80000 currencyCode=EUR/%26gt;%26lt;br/%26gt;

%26lt;/body%26gt;
%26lt;/html%26gt;

2.格式化日期

类似于数字和货币格式化，本地化环境还会影响生成日期和时间的方式。

%26lt;%@ taglib prefix=fmt uri=http://java.sun.com/jsp/jstl/fmt %%26gt;

%26lt;html%26gt;
%26lt;head%26gt;
%26lt;title%26gt;Date Formatting%26lt;/title%26gt;
%26lt;/head%26gt;
%26lt;body%26gt;
%26lt;h1%26gt;Date Formatting and locale%26lt;/h1%26gt;
%26lt;fmt:timeZone value=EST%26gt;
%26lt;jsp:useBean id=currentTime class=java.util.Date/%26gt;

%26lt;h3%26gt;English, Great Britain%26lt;/h3%26gt;
%26lt;fmt:setLocale value=en_GB /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;English, USA%26lt;/h3%26gt;
%26lt;fmt:setLocale value=en_US /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;French, France%26lt;/h3%26gt;
%26lt;fmt:setLocale value=fr_FR /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Japanese, Japan%26lt;/h3%26gt;
%26lt;fmt:setLocale value=ja_JP /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Korean, Korea%26lt;/h3%26gt;
%26lt;fmt:setLocale value=ko_KR /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Spanish, Spain%26lt;/h3%26gt;
%26lt;fmt:setLocale value=es_ES /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;h3%26gt;Arabic, Egypt%26lt;/h3%26gt;
%26lt;fmt:setLocale value=ar_EG /%26gt;
%26lt;fmt:formatDate type=both dateStyle=full timeStyle=full value=${currentTime} /%26gt;%26lt;br/%26gt;

%26lt;/fmt:timeZone%26gt;
%26lt;/body%26gt;
%26lt;/html%26gt;
