1.pom.xml文件加入servlet包
4.0.0
com.citywy
mytest02war
0.0.1-SNAPSHOT
junit

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class UserServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public UserServlet() {
super();
} protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
} protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;
charset=utf-8");
String name=request.getParameter("uname");
String pwd=request.getParameter("upwd");
System.out.println("输出"+name+"--"+pwd);
request.setAttribute("someinfo", "这是登陆成功提示信息！");
request.getRequestDispatcher("index.jsp").forward(request, response);
}}
