第一种，不推荐

第二种，只是一种思想

常用第三种、第四种

环境要求：

官网：https://docs.spring.io/spring-session/reference/guides/boot-redis.html

xml配置：

        
            org.springframework.boot
            spring-boot-starter-data-redis
        
        
            org.springframework.session
            spring-session-data-redis
        

yaml配置

spring:
  redis:
    host: 你的主机
    port: 你的端口
  session:
    store-type: redis #用redis存session数据
server:
  servlet:
    session:
      timeout: 30m #session过期时间

主类标@EnableRedisHttpSession注解

配置:

• 配置cookie：https://github.com/spring-projects/spring-session/blob/2.7.0/spring-session-samples/spring-session-sample-javaconfig-custom-cookie/src/main/java/sample/Config.java
• 配置使用json序列化:https://github.com/spring-projects/spring-session/blob/2.7.0/spring-session-samples/spring-session-sample-boot-redis-json/src/main/java/sample/config/SessionConfig.java
