Spring整合redis（jedis）实现Session共享 Spring整合redis（jedis）实现Session共享的过程
Z涛子 人气:0今天来记录一下自己在整合框架过程中所遇到的问题：
1. 在用redis实现session共享时，项目启动报 No bean named 'springSessionRepositoryFilter' is defined 异常
2. 在调用缓存工具类的时候显示注入的JedisPool为Null （一个跟spring扫描有关的细节错误）
好了，开始上我整合的文件了

以上是整合的配置文件，其中有关redis的配置是整合成功的关键
问题总结
1.之前整合完启动项目报异常，是因为配置文件放置的位置问题，以至于启动不成功，多试几遍，以上的配置文件是可以用的
2.之前调用缓存工具类，显示注入JedisPool为空，在controller那边注入又有值，是因为我在controller那边调用工具类的方式是new出来的，所以导致spring在扫描那个工具类时丢失Jedispool注入，在controller中改用注入工具类的形式即可解决
例如：
