编译servlet时出错

Question

我写了一个简单的servlet:

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class TestingServlet extends HttpServer {

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("<H1>Hello world</H1>");
    }
}

我试着编译它并获得:

TestingServlet.java:6:错误:找不到符号公共类TestingServlet扩展HttpServer {^符号:类HttpServer 1错误

我该如何解决？

Answer 1

我相信你在找javax.servlet.http.HttpServlet.

public class TestingServlet extends HttpServlet {

HttpServer您导入的任何软件包中都没有类.
