快两年没有写过JavaEE代码了，今天晚上心血来潮想写个Servlet，

使用浏览器访问http://127.0.0.1:8080/MyTest/xx?name=aaa 一直报这个错误，我的Servlet代码如下

public class MyServlet extends HttpServlet{

@Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String name = req.getParameter("name");
name = name==null?"传入的name为空":name;
PrintWriter pw = resp.getWriter();
pw.print(name);
super.doGet(req, resp);
}

@Override
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
              super.doPost(req, resp);
}

}

解决办法：

搞了好长时间发现应该把doGet和doPost里面的那个super.doGet(req, resp);   super.doPost(req, resp);给注释掉，,否则总会调用父类HttpServlet的doGet或doPost方法

HttpServlet 中doGet方法如下：

    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
        throws ServletException, IOException
    {
        String protocol = req.getProtocol();
        String msg = lStrings.getString("http.method_get_not_supported");
        if (protocol.endsWith("1.1")) {
            resp.sendError(HttpServletResponse.SC_METHOD_NOT_ALLOWED, msg);
        } else {
            resp.sendError(HttpServletResponse.SC_BAD_REQUEST, msg);
        }
    }

通过这个代码不难看出浏览器为什么会看到那些错误信息了。
