Question

我正在尝试获取用户区域设置语言，当他访问我的网站并以该语言显示网站时。如何检测用户区域设置并附加到浏览器网址，就像我们从印度访问http://www.microsoft.com时那样它会自动显示网址为http://www.microsoft.com/en-in/default.aspx所以我的网站名称为http://www.myweb.com，那么如何在网页加载时将网址设为http://www.myweb.com?language=en ..？因为我在我的web.xml中将home.jsp设置为欢迎文件所以当我从netbeans运行我的web应用程序时它显示localhost：8080 / Myweb / so如果我想发送页面，用户如何知道该页面是英文或荷兰语链接到我在荷兰的朋友？总之，我想在用户打开我的网站时显示URL中的语言参数，如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>

Answer 1

编写一个HttpFilter来处理它并将其映射到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());
  }
 }

没有为我工作（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);
}
