spring session 设置缓存集群session共享

增加redis和springsession 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>2.1.9.RELEASE</version>
</dependency>

在程序启动入口增加：@EnableRedisHttpSession

@EnableRedisHttpSession(maxInactiveIntervalInSeconds=3600) //redis session 启用,设置session在redis中过期时间

其他然后在配置文件增加redis主机配置：

spring.redis.database=2
spring.redis.host=localhost
spring.redis.password=
spring.redis.port=6379
