Servlet3：

package cn.xtnotes.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;

public class Servlet3 extends HttpServlet {

	
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
		request.setCharacterEncoding("utf-8"); //设置请求数据编码
		response.setCharacterEncoding("utf-8");//设置响应数据编码
		String s=request.getParameter("name");
		PrintWriter pw=response.getWriter();
		pw.print("请求参数:"+s);
	}

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