当他访问我的网站并以该语言显示网站时，我正在尝试获取用户区域设置语言。如何检测用户区域设置并附加到浏览器 url，就像我们从印度访问http://www.microsoft.com时一样，然后它会自动显示 url作为http://www.microsoft.com/en-in/default.aspx例如我的网站名称是http://www.myweb.com那么如何将 url 设为http://www.myweb.com？页面加载时语言=en ..？因为我在 web.xml 中将 home.jsp 设置为欢迎文件，所以当我从 netbeans 运行我的网络应用程序时，它显示 localhost:8080/Myweb/ 所以如果我想发送页面，用户如何知道该页面是英文还是荷兰文链接到我在荷兰的朋友？简而言之，当用户打开我的网站时，我想在 URL 中显示语言参数http://www.myweb.com?language=nl即自动检测用户区域设置并将该语言设置为参数

这是我的代码....

  <%@page import="java.util.Locale"%>
  <%@ page pageEncoding="UTF-8" %>
  <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
  <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
  <%
   String userLocale = request.getHeader("Accept-Language");
   //out.println(userLocale);
   Locale locale = request.getLocale();
   String userlanguage = locale.getDisplayLanguage();
   out.println("LANG :" + locale.getLanguage());
  %>

  <c:set var="language" value="${not empty param.language ? param.language : not empty language ? language : pageContext.request.locale.language}" scope="session" />
  <fmt:setLocale value="${language}" />

 // here depending on user locale i am setting basename is this good approach?
  <c:choose>
  <c:when test="${language == 'nl'}">
    <fmt:setBundle basename="com.example.i18n.text_nl" />
  </c:when>
  <c:otherwise>
    <fmt:setBundle basename="com.example.i18n.text" />
  </c:otherwise>
  </c:choose>


   <html lang="${language}">
    <nav>
        <ul>
          <li>
              <a href="<c:url value='Aboutus.jsp?language=${language}'/>" 
                 title="<fmt:message key="nav.label.aboutus" />">
                 <fmt:message key="nav.label.aboutus" />
              </a>
         </li>
         <li class="shad">
              <a href="<c:url value='Contactus.jsp?language=${language}'/>"  // and also is this good way to append language as parameter to url here ?
                 title="<fmt:message key="nav.label.contactus" />">
                <fmt:message key="nav.label.contactus" />
             </a>
        </li>
       </ul>
   </nav>      
   </html>

编写一个 HttpFilter 来处理这个问题并将其映射到 web.xml 中。

 if(request.getParameter("language")==null) {
  String userLocale = request.getHeader("Accept-Language");
  Locale locale = request.getLocale();

  if(req.getRequestUrl().contains("?")) {
   response.sendRedirect(req.getRequestUrl()+"&language="_locale.getLanguage());
  } else {
   response.sendRedirect(req.getRequestUrl()+"?language="_locale.getLanguage());
  }
 }

对我没用（也许现在已经过时了？）

这是我的更新版本：

public void doFilter(ServletRequest request, ServletResponse response,
    FilterChain chain)
    throws IOException, ServletException {

    if (request instanceof HttpServletRequest) {
        HttpServletRequest req = (HttpServletRequest) request;
        HttpServletResponse res = (HttpServletResponse) response;

        if (request.getParameter("language") == null) {
            Locale locale = request.getLocale();

            String qs = req.getQueryString();
            if (qs == null || qs.isEmpty()) {
                res.sendRedirect(req.getRequestURI() + "?language=" + locale.getLanguage());
            } else {
                res.sendRedirect(req.getRequestURI() + "?" + qs + "&language=" + locale.getLanguage());
            }
        }
    }

    chain.doFilter(request, response);
}
