篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了多系统多方式单点登入相关的知识，希望对你有一定的参考价值。
目录
SSO单点登录
SOO(Single Sign On) 单点登录
单点流程
cookie是用来在客户端存储数据的工具。
1、在其中一个子系统中登录，转到登录系统，在登录系统中完成登录，完成登录后向发起登录的子系统写入一个cookie
2、其他系统进行登录时，先判断是否存在token信息，存在及返回用户信息，没有统一到登陆地址页面进行登入，其他系统进行刷新即可
3、cookie中的子系统的域名，保持一致，所有的子系统才能访问到这个cookie
实现多系统单点登录
1、以springboot为项目背景

2、修改host文件，刷新dns
#sso
127.0.0.1 www.codeshop.com
127.0.0.1 vip.codeshop.com
127.0.0.1 cart.codeshop.com
127.0.0.1 login.codeshop.com
3、创建父项目及多个子系统项目

3.1、启动类（单个）
package com.cn;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
/**
* @创建人 明
*/
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
@Bean
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
3.2、配置（单个）
server:
port: 9003
4、登录系统，负责token生成，写入。子系统登录页面拦截，负责db用户信息校验，登入用户信息退出
package com.cn.hm.controller;
import com.cn.hm.util.LogginCacheUtil;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CookieValue;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.thymeleaf.util.StringUtils;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpSession;
/*
*@描述
*@参数 视图控制
*@返回值
*@创建人 HM
*@创建时间
*@修改人和其它信息
*/
@Controller
@RequestMapping("/view")
public class ViewController {
/**
*@描述
*@参数 跳转到登入页面
*@返回值
*@创建人 HM
*@创建时间
*@修改人和其它信息
*/
@GetMapping("/login")
public String toLogin(@RequestParam(required = false,defaultValue = "") String target
, HttpSession session
, @CookieValue(required = false,value = "TOKEN")Cookie cookie){
if(StringUtils.isEmpty(target)){//主页地址
target="http://www.codeshop.com:9002/view/index";
}
//进入登入系统，判断是否存在token
if(cookie!=null && LogginCacheUtil.loginUser.get(cookie.getValue())!=null){
return "redirect:"+target;
}
//地址校验
//存入本次交互会话
session.setAttribute("target",target);
return "login";
}
}
package com.cn.hm.controller;
import com.cn.hm.pojo.User;
import com.cn.hm.util.LogginCacheUtil;
import org.springframework.http.HttpStatus;
