SpringBoot 如何实现Session共享

作者：mySoul

这篇文章主要介绍了SpringBoot 如何实现Session共享，帮助大家更好的理解和学习spring boot框架，感兴趣的朋友可以了解下

HttpSession，是通过Servlet容器创建并进行管理的，创建成功以后将会保存在内存中，这里将会使用Redis解决session共享的问题。

创建项目

添加pom

添加相关的maven

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

配置redis连接

配置redis连接

spring:
 redis:
  database: 0
  host: 106.53.115.12
  port: 6379
  password: 12345678
  jedis:
   pool:
    max-active: 8
    max-idle: 8
    max-wait: -1ms
    min-idle: 0

创建Controller用来执行测试操作

package com.example.demo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpSession;

@RestController
public class HelloController {
  @PostMapping("/save")
  public String saveName(String name, HttpSession session){
    session.setAttribute("name", name);
    return "8080";
  }

  @GetMapping("/get")
  public String getName(HttpSession httpSession){
    return httpSession.getAttribute("name").toString();
  }
}

Nginx 负载均衡

mingming@xiaoming-pc:~$ sudo apt-get install nginx

修改配置文件

upstream sang.com {
    server 192.168.0.1:8080 weight = 1;
    server 192.168.0.2:8080 weight = 1;
}


server {
    listen 80;
    server_name localhost;
    location / {
        proxy_pass http://sang.com;
        proxy_redirect default;
    }

}

请求分发

保存数据

获取数据
