使用Ajax本地化表單提交

Question

我正在使用Spring框架與Tomcat 7 & MySQL。我正在使用UTF-8編碼爲本地語言提交表單數據。這可以正常使用通過JSP發佈。但是，當使用基於Ajax的表單提交時，它將垃圾字符顯示爲服務器中的請求參數。

請讓我知道如果我錯過什麼..

** My Ajax Code** 

    xmlHttp.open("POST", "viewTeluguScript.htm", true); 
    //xmlHttp.setRequestHeader("Content-type", "multipart/form-data;charset=UTF-8"); 
    xmlHttp.setRequestHeader("Content-length", parameters.length); 
    // xmlHttp.setRequestHeader("Content-Type", "text/html;charset=UTF-8"); 
    xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded;charset=UTF-8"); 
    //xmlHttp.setRequestHeader("pageEncoding","UTF-8"); 
    //xmlHttp.setRequestHeader("accept-charset","UTF-8"); 
    xmlHttp.setRequestHeader("content-language","tel"); 
    xmlHttp.setRequestHeader("Connection", "close"); 
    xmlHttp.send(parameters); 


    **My Controller code** 

    public ModelAndView viewTeluguScript(HttpServletRequest request, HttpServletResponse response) throws SQLException, CannotGetJdbcConnectionException, Exception { 

    //textInfo = java.net.URLDecoder.decode(request.getParameter("teluguText"), "UTF-8"); 
    textInfo = request.getParameter("teluguText"); 
    /* StringBuffer jb = new StringBuffer(); 
    String line = null; 
    try { 
    BufferedReader reader = request.getReader(); 
    while ((line = reader.readLine()) != null) 
    jb.append(line); 
    } catch (Exception e) { 


    } 

    System.out.println("request is :::: "+jb.toString());*/ 


    ModelAndView mv = new ModelAndView("viewQuestions"); 
    //request.getSession().setAttribute("workingModule", "questions"); 
    return mv; 
    }

    **My web.xml**

嘗試添加內容編碼HTTP頭 您的瀏覽器使用Unicode來表示要顯示的數據。來自Web服務器的資源可以選擇在http頭中附加編碼信息。 如果存在內容編碼標頭，瀏覽器會使用響應標頭中的編碼將資源轉換爲內部unicode表示。如果沒有內容編碼頭，瀏覽器會假定文件編碼與請求資源的頁面相同。
