1.pom文件：

2.MVC页面跳转配置类，如果请求直接跳转页面，采用该配置可以减少controller中代码的编写

package com.xicheng.ssodemo.common;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @author xichengxml
 * @date 2019/2/13 16:56
 */
@Configuration
public class SpringMvcConfig implements WebMvcConfigurer {

  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("login").setViewName("login");
    registry.addViewController("success").setViewName("success");
    registry.addViewController("error").setViewName("error");
  }
}

3.核心校验类编写

package com.xicheng.ssodemo.common;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;

/**
 * @author xichengxml
 * @date 2019/2/13 16:19
 * 登录校验工具类
 */
public class LoginCheck {

  /** 用户名 */
  private static final String USERNAME = "uname";
  /** 密码 */
  private static final String PASSWORD = "pwd";
  /** cookie键 */
  public static final String COOKIE_KEY = "sso";
  /** cookie值 */
  public static final String COOKIE_VAL = "ssocookie";

  /**
   * 校验用户名和密码
   * @param userName 登录用户名
   * @param password 登录密码
   * @return 成功返回true; 失败返回false
   */
  public static boolean checkLogin(String userName, String password) {
    return USERNAME.equals(userName) && PASSWORD.equals(password);
  }

  /**
   * 校验cookie
   * @param request
   * @return
   */
  public static boolean checkCookie(HttpServletRequest request) {
    Cookie[] cookies = request.getCookies();
    if (cookies != null && cookies.length != 0) {
      for (Cookie cookie : cookies) {
        if (COOKIE_KEY.equals(cookie.getName()) && COOKIE_VAL.equals(cookie.getValue())) {
          return true;
        }
      }
    }
    return false;
  }
}

4.核心登录controller编写

package com.xicheng.ssodemo.controller;

import com.xicheng.ssodemo.common.LoginCheck;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletResponse;

/**
 * @author xichengxml
 * @date 2019/2/13 16:31
 */
@Controller
public class LoginController {

  /**
   * 登录成功后保存cookie在域下，返回登录成功页
   * @param uname
   * @param pwd
   * @param response
   * @return
   */
  @RequestMapping("/do-login")
  public String doLogin(String uname, String pwd, HttpServletResponse response) {
    if (LoginCheck.checkLogin(uname, pwd)) {
      Cookie cookie = new Cookie(LoginCheck.COOKIE_KEY, LoginCheck.COOKIE_VAL);
      cookie.setPath("/");
      response.addCookie(cookie);
      return "success";
    }
    return "error";
  }

}

5.登录controller编写

package com.xicheng.ssodemo.controller;

import com.xicheng.ssodemo.common.LoginCheck;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;

/**
 * @author xichengxml
 * @date 2019/2/13 17:53
 */
@Controller
public class SameOriginController {

  /**
   * cookie存在，登录成功；否则返回登录页
   * @param request
   * @return
   */
  @RequestMapping("/login01")
  public String demo01(HttpServletRequest request) {
    return LoginCheck.checkCookie(request) ? "success" : "login";
  }

  @RequestMapping("/login02")
  public String demo02(HttpServletRequest request) {
    return LoginCheck.checkCookie(request) ? "success" : "login";
  }

}

6.登录页面及成功失败页面编写

<!-- login.html -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>登录</title>
  <script src="/js/vue.js" type="text/javascript"></script>
  <script src="/js/element.js" type="text/javascript"></script>
  <script src="/js/axios.min.js" type="text/javascript"></script>
  <link href="/css/element.css" rel="external nofollow" rel="stylesheet" type="text/css"/>
</head>
<body>
  <div id="app">
    <el-input v-model="uname" placeholder="请输入用户名"></el-input>
    <el-input v-model="pwd" placeholder="请输入密码"></el-input>
    <el-button @click="submit" type="primary">登录</el-button>
  </div>

  <script>
    new Vue({
      el: "#app",
      data: {
        uname: '',
        pwd: ''
      },
      methods: {
        submit: function () {
          // 获取用户名和密码
          var uname = this.uname;
          var pwd = this.pwd;
          // 发送http请求
          axios.get("do-login", {params: {uname: uname, pwd: pwd}})
            .then(function (response) {
              if(response.status == 200) {
                location.href = "/success";
              } else {
                location.href = "/error";
              }
            })
            .catch(function (error) {
              alert("error--" + error);
            })
        }
      }
    });
  </script>
</body>
</html>

<!-- success.html -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>成功页面</title>
</head>
<body>
  This is success page!
</body>
</html>

<!-- error.html -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>错误页面</title>
</head>
<body>
  This is error page!
</body>
</html>
