HttpServletRequest.setCharacterEncoding("gb2312");编译时报如下错

Question

package com.jspdev.ch7;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;public class DoGetTestServlet extends HttpServlet
{
public void doGet(HttpServletRequest request,
                      HttpServletResponse response)
        throws IOException, ServletException
    {
        // request.setCharacterEncoding("gb2312");
        response.setContentType("text/html;charset=gb2312");
        PrintWriter out = response.getWriter();
        out.println("获得了以下的参数值何国伟大预言家：name=<br>"+request.getParameter("name"));
        out.flush();       
    }   
}
如果加上如下语句
request.setCharacterEncoding("gb2312");
编译时报如下错
cannot resolve symbol
symbol:method setCharacterEncodeing<java.lang.strig>
location:interface javax.servlet.http.httpServletRequest
request.setCharacterEncoding<"gb2312">不要则编译通过，这是怎样处理呀

Answer 1

request.setCharacterEncoding("gb2312"); 应该是可以的

Answer 2

其实编译告诉你很清楚了编译时报如下错
cannot resolve symbol
symbol:method setCharacterEncodeing<java.lang.strig>你是不是哪里写错了

Answer 3

setCharacterEncodeing???
---------------------
setCharacterEncoding才是！！
