基于SpringBoot,SpringSession和redis的会话共享

安装redis

$ wget http://download.redis.io/releases/redis-4.0.1.tar.gz$ tar xzf redis-4.0.1.tar.gz$ cd redis-4.0.1$ make

配置redis.conf，允许外部连接

使用IntelliJ IDEA创建Spring Boot工程，选择web, redis, session.

LoginController.java

package com.example.springsessiondemo;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;@Controllerpublic class LoginController {    @RequestMapping("/")    @ResponseBody    public String home(HttpServletRequest request, HttpServletResponse response) {        HttpSession session = request.getSession();        User user = (User) session.getAttribute("user");        if (user == null){            return "用好未登录" + session.getId();        } else {            return "用好已登录" + session.getId();        }    }    @RequestMapping("/login")    @ResponseBody    public String login(HttpServletRequest request){        User user = new User();        user.setUsername("chf");        user.setPassword("pass");        request.getSession().setAttribute("user", user);        return "登录成功 "  + request.getSession().getId();    }}

创建文件config.java

@Configuration@ImportResource(locations={"classpath:spring.xml"})public class Config {}

配置文件application.yaml

server:  port: 8000spring:  session:    store-type: redis  redis:    host: 10.0.0.201    port: 6379    password:

配置文件spring.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="defaultCookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer">        <property name="domainName" value="example.com"/>        <property name="cookieName" value="JSESSIONID"/>        <property name="cookiePath" value="/" />        <!-- <property name="domainNamePattern" value="^.+?\.(\w+\.[a-z]+)$"></property>-->    </bean>    <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">        <property name="maxInactiveIntervalInSeconds" value="1800" />        <property name="cookieSerializer" ref="defaultCookieSerializer"/>    </bean></beans>

配置hosts文件

127.0.0.1 www.example.com
127.0.0.1 passport.example.com

运行程序，通过浏览器访问passport.example.com:8000

访问www.example.com:8000

JSESSIONID的内容相同，说明实现了会话共享。

接下来在passport进行登录

切换到www

一个简单的单点登录系统就实现了。
