你好

Helloservlet里面的代码如下，没有配置web.xml因为已经有了注解

package servlet;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

* Servlet implementation class Helloservlet

*/

@WebServlet("/Helloservlet")

public class Helloservlet extends HttpServlet {

private static final long serialVersionUID = 1L;

/**

* Default constructor.

*/

public Helloservlet() {

// TODO Auto-generated constructor stub

}

/**

* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)

*/

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

doPost(request, response);

response.getWriter().append("Served at: ").append(request.getContextPath());

System.out.println("很好");

PrintWriter out=response.getWriter();

response.setContentType("text/html;charset=utf-8");

out.println("xixi");

}

/**

* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)

*/

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

doGet(request, response);

System.out.println("很好");

PrintWriter out=response.getWriter();

response.setContentType("text/html;charset=utf-8");

out.println("xixi");

}

}

但是一直出现以下问题，已经一个消失了都没有解决成功，求大神来解答
