1.通过选择来实现国际化的功能:
在国际化的ResourceBundle使用介绍的文章的基础上,我们新建一个login.jsp的页面.
login.jsp的代码如下.
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
<script type="text/javascript">
function sendForm(){
document.getElementById("f").submit();
}
</script>
</head>
<body>
<form id="f" action="${pageContext.request.contextPath}/login.jsp" method="post">
<select name="country" onchange="sendForm()">
<option>--选择国家--</option>
<option value="china">中国</option>
<option value="us">US</option>
</select>
</form>
<%
String country = request.getParameter("country");
ResourceBundle bundle = null;
if("us".equals(country)){
bundle=ResourceBundle.getBundle("message",Locale.US);
}else{
bundle=ResourceBundle.getBundle("message",Locale.CHINA);
}
%>
<h1><%=bundle.getString("title") %></h1>
<form>
<%=bundle.getString("username") %>:<input type="text" name="username"><br>
<%=bundle.getString("password") %>:<input type="password" name="password"><br>
<input type="submit" value="<%=bundle.getString("submit") %>">
</form>
</body>
</html>
然后修改message_en_US.properties配置文件的内容.
title=LOGIN WINDOM username=USERNAME password=PASSWORD submit=LOGIN
然后修改message_zh_CN.properties配置文件的内容.
title=\u767B\u5F55\u7A97\u53E3 username=\u7528\u6237\u540D password=\u5BC6\u7801 submit=\u767B\u5F55
默认会显示中文页面.
当我选择US时,页面就会显示英文的.
2.通过获取浏览器的语言来自动实现国际化功能.
添加一个login1.jsp的页面.
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
</head>
<body>
<%
String country = request.getHeader("accept-language"); //通过获取accept-language
ResourceBundle bundle = null;
if(country.startsWith("zh-CN")){ //这里我判断country是不是zh-CN 语言,若是中文语言让其显示英文网页.(正常是zh-CN就显示中文,en-US就显示英文,这里为了方便测试效果)
bundle=ResourceBundle.getBundle("message",Locale.US);
}else{
bundle=ResourceBundle.getBundle("message",Locale.CHINA);
}
%>
<h1><%=bundle.getString("title") %></h1>
<form>
<%=bundle.getString("username") %>:<input type="text" name="username"><br>
<%=bundle.getString("password") %>:<input type="password" name="password"><br>
<input type="submit" value="<%=bundle.getString("submit") %>">
</form>
</body>
</html>
页面就自动显示为英文的了.
