shiro使用redis缓存,实现session共享,spring-data-redis集群配置

时间:2021-11-20 20:36:43

使用mvc环境,spring-data-redis所需jar包版本如下,版本不同会报包冲突:

spring4.2.8

spring-data-redis-1.7.4

spring-data-commons-1.12.4

jedis-2.9.0 --依赖commons-lang3-3.3.2

通过shiro管理session,将session缓存到redis数据库,可以实现在应用集群下session共享。

首先配置spring-context-shiro.xml,这里引用jeesite配置进行修改,重点关注session缓存配置

shiro框架首次访问缓存,先去执行get方法,没有返回为空。
