## 场景描述 ##

springboot项目用redis解决session共享问题，启动项目报错。  
springboot版本：  
  
org.springframework.boot  
spring-boot-starter-parent  
1.5.19.RELEASE

redis版本

\[15332\] 12 Mar 15:59:54.307 \# Server started, Redis version 2.6.12  
\[15332\] 12 Mar 15:59:54.308 \* The server is now ready to accept connections on port 6379

--------------------

## 异常原因 ##

redis服务器版本和jar包版本不一致造成的  
maven仓库的 spring-boot-starter-redis1.3.8的只支持2.7.3 的redis

--------------------

## 解决方案 ##

更换redis服务器版本为springboot兼容的版本。这里更换为3.0。  
\[25072\] 12 Mar 16:01:52.065 \# Server started, Redis version 3.0.501  
\[25072\] 12 Mar 16:01:52.065 \* The server is now ready to accept connections on port 6379
