关于POST提交的一个小问题

<form action="servlet/ThirdServlet?userName=1&passWord=2" method="post">
    <input type="submit" value="提交">
</form>

public class ThirdServlet extends HttpServlet {

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String userName = request.getParameter("uesrName");
String passWord = request.getParameter("passWord");
response.getWriter().println("userName --->"+userName);
response.getWriter().println("passWord---->"+passWord);
}

}

为什么passWord能取到值，而userName取不到值得？
[解决办法]

String userName = request.getParameter("uesrName");

你的userName写错了，这种情况最好复制粘贴。。。
