2. two.jsp 视图

   <%@ page language="java" contenttype="text/html; charset=utf-8"    pageencoding="utf-8"%>

3. two控制器

   package ghy.webapp.myapp;import org.springframework.stereotype.controller;import org.springframework.web.bind.annotation.requestmapping;import org.springframework.web.bind.annotation.requestparam;import org.springframework.web.bind.annotation.responsebody;@controller  public class twocontroller {            @requestmapping("login") //用来处理前台的login请求      private @responsebody string hello(              @requestparam(value = "username", required = false)string username,              @requestparam(value = "password", required = false)string password              ){          return "hello "+username+",your password is: "+password;                }   }

   环境：sts +tomcat
