下面我们将在springcloud微服务项目中，使用redis实现简单高效的session共享。
了解springcloud架构可以加求求：三五三六二四七二五九
新建一个spring boot项目，命名springcloud-session-redis

POM依赖配置

配置文件
在application.yml中加入redis、eureka、port等配置

server:
  port: 8090
spring:
  application:
    name: service-session-redis
  redis:
    host: 192.168.68.100
    port: 6379
    password: 123456
    timeout: 6000ms
    lettuce:
      pool:
        max-active: 8
        max-wait: -1ms
        max-idle: 8
        min-idle: 0
    database: 0
eureka:
  client:
    serviceUrl:
      defaultZone: http://admin:123456@localhost:8761/eureka/
management: 
  endpoints:
    web:
      exposure: 
        include: "*"
      cors:
        allowed-origins: "*"
        allowed-methods: "*"

Redis Session配置类

package com.carry.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
}

控制层Controller中添加测试方法

package com.carry.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RefreshScope
public class UserManagementController {
    /**
     * redis sesion共享
     * 
     * @param request
     * @return
     */
    @GetMapping("/getUser")
    public String getUser(HttpServletRequest request) {
        HttpSession session = request.getSession();
        String username = (String) session.getAttribute("username");
        if (StringUtils.isEmpty(username)) {
            username = "testSessionRedis|" + System.currentTimeMillis();
            session.setAttribute("username", username);
        }
        System.out.println("访问端口：" + request.getServerPort());
        return username;
    }
}
