SSO单点登录
2019-11-24 16:02:53来源:博客园 阅读 ()
单点登录系统介绍
单点登录(Single Sign On),简称为 SSO,是目前比较流行的企业业务整合的解决方案之一。SSO 的定义是在多个应用系统中,用户只需要登录一次就可以访问所有相互信任的应用系统。
单点登录的实现原理
实现单点登录,就是解决如何产生和存储那个信任,再就是其他系统如何验证这个信任的有效性。因此,也就需要解决以下两点:
- 存储信任
- 验证信任

客户端使用Cookie保存用户登录状态-Token
package com.soldier.ego.beans; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.UnsupportedEncodingException; import java.net.URLDecoder; import java.net.URLEncoder; /** * @ProjectName:ego * @author:soldier * @Email:583403411@qq.com * @create:19-11-24下午5:04 * @Describe:Cookie工具类 **/ public final class CookieUtils { /** * 得到Cookie的值, 不编码 * * @param request * @param cookieName * @return */ public static String getCookieValue(HttpServletRequest request, String cookieName) { return getCookieValue(request, cookieName, false);

domainName = ary[0]; } return domainName; } }CookieUtils.class
1、登录按钮与注册按钮的定义
<li class="fore1" id="loginbar" clstag="homepage|keycount|home2013|01b">您好!欢迎来到易购!<a href="javascript:login()">[登录]</a> <a href="javascript:register()">[免费注册]</a></li>
function login() { // 页面跳转 return location.href = "http://localhost:8083/login"; } function register() { // 页面跳转 return location.href = "http://localhost:8083/register"; }
2、登录提交与注册提交
doLogin:function() { $.post("/user/login", $("#formlogin").serialize(),function(data){ if (data.status == 200) { alert("登录成功!"); if (redirectUrl == "") { //重定向到ego的门户首页 location.href = "http://localhost:8081/index.html"; } else { location.href = redirectUrl; } } else { alert("登录失败,原因是:" + data.msg); $("#loginname").select(); } }); }登录提交.js
doSubmit:function() { $.post("/user/register",$("#personRegForm").serialize(), function(data){ if(data.status == 200){ alert('用户注册成功,请登录!'); location.href = "/login"; //注册成功,跳转到登录页面 } else { alert("注册失败!"); } }); }注册提交.js
3、客户端校验登录状态与退出登录
checkLogin : function(){ var _ticket = $.cookie("SSO_TOKEN"); if(!_ticket){ return ; } $.ajax({ url : "http://localhost:8083/user/token/" + _ticket, dataType : "jsonp", type : "GET", success : function(data){ if(data.status == 200){ var username = data.data.username; // var html = username + ",欢迎来到淘淘!<a href=\"http://www.taotao.com/user/logout.html\" class=\"link-logout\">[退出]</a>"; var html = username + ",欢迎来到淘淘!<a href=\"javascript:TT.logout()\" class=\"link-logout\">[退出]</a>"; $("#loginbar").html(html); } } }); }, logout: function () { // 获取本地保存的SSO_TOKEN var _ticket = $.cookie("SSO_TOKEN"); if(!_ticket){ return ; } $.ajax({ url : "http://localhost:8083/user/logout/" + _ticket, dataType : "jsonp", type : "GET", success : function(data){ if(data.status == 200){ location.href = 'http://localhost:8081'; } } }); }校验与退出登录.js
4、修改SsoUserServiceImpl的两个方法
@Override public EgoResult userLogin(String username, String password, HttpServletRequest request, HttpServletResponse response) { EgoResult result = new EgoResult(); result.setStatus(400); result.setData(null); result.setMsg("用户名或密码错误."); TbUser tbUser = userServiceProxy.selectUserByUserNameService(username); if (tbUser != null) { //对前端提交的密码进行加密 password = DigestUtils.md5DigestAsHex(password.getBytes()); if (password.equals(tbUser.getPassword())) { // 将当前登录用户对象,转为json字符串,保存到redis数据库 String userJsonStr = JsonUtils.objectToJson(tbUser); String token = UUID.randomUUID().toString(); // 将用户信息保存到redis数据库 jedisCluster.set(token, userJsonStr); // 设置token的有效期为30分钟 jedisCluster.expire(token, 1800); /** * 将token响应到客户端 */ CookieUtils.setCookie(request,response, "SSO_TOKEN", token); result.setStatus(200); result.setMsg("登录成功."); result.setData(token); } } return result; } @Override public EgoResult loadUserByToken(String token) { EgoResult result = new EgoResult(); result.setStatus(400); result.setMsg("error"); result.setData(null); String userJsonStr = jedisCluster.get(token); if (!StringUtils.isEmpty(userJsonStr)) { result.setStatus(200); result.setMsg("ok"); // result.setData(userJsonStr); TbUser tbUser = JsonUtils.jsonToPojo(userJsonStr, TbUser.class); result.setData(tbUser); } return result; }userLogin(),loadUserByToken()
5、修改controller中拦截登录的方法
/** * 实现用户登录 * @param username 用户名 * @param password 密码 * @param request request对象是服务器对浏览器请求的封装 * @param response response是服务器对服务器响应的封装 * @ResponseBody 异步的,不会进行跳转 */ @RequestMapping(value = "/user/login", method = RequestMethod.POST) @ResponseBody public EgoResult userLogin(String username, String password, HttpServletRequest request, HttpServletResponse response) { return ssoUserService.userLogin(username, password, request, response); }
