　　package servlet;

　　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 TestServlet

　　*/

　　@WebServlet("/test")

　　public class TestServlet extends HttpServlet {

　　private static final long serialVersionUID = 1L;

　　/**

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

　　*/

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

　　String name = request.getParameter("name");

　　System.out.println("name:" + name);

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

　　}

　　/**

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

　　*/

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

　　//request.setCharacterEncoding 只能解决post 乱码问题

　　request.setCharacterEncoding("utf-8");

　　doGet(request, response);

　　}

　　}
