Redis连接工厂配置

package com.xwb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@EnableRedisHttpSession()
@SpringBootApplication(exclude = org.springframework.boot.autoconfigure.session.SessionAutoConfiguration.class)
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setHostName("127.0.0.1");
        factory.setPort(6379);
        return factory;
    }
}

Controller

package com.xwb.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

@RestController
public class SessionShareController {
    private static final Logger LOGGER = LoggerFactory.getLogger(SessionShareController.class);
    @GetMapping("/login")
    public String share(HttpServletRequest request){
        request.getSession().setAttribute("userId", "123456");
        LOGGER.info("port:{}, login success", request.getLocalPort());
        return "login success";
    }

    @GetMapping("/user")
    public String getUser(HttpServletRequest request){
        LOGGER.info("port:{}, get user", request.getLocalPort());
        HttpSession session = request.getSession();
        return session.getAttribute("userId").toString();
    }
}

测试

1. 将项目打成可运行jar包
   • 项目根目录下执行mvn package
2. 将项目分别运行在两个不同的端口下
   • 进入jar包所在目录执行命令java -jar spring-session-share-1.0.0.jar --server.port=8080 --server.context-path=/test
   • 更改端口，重复上一步java -jar spring-session-share-1.0.0.jar --server.port=8888 --server.context-path=/test
3. 配置Nginx

#user  nobody;
worker_processes  1;

events {
    worker_connections  1024;
}

http {
    upstream xwb-session-share {
        server 127.0.0.1:8080;
        server 127.0.0.1:8888;
    }
    
    server {
        listen 80;
        server_name      localhost;

        location / {
            proxy_pass   http://xwb-session-share;
        }
    }
}

4. 启动Nginx后，访问页面
   • 登录localhost/test/login
   • 多次访问localhost/test/user
   • 查看日志，验证结果

登录

第一次访问/test/user

第二次访问/test/user
