Spring整合redis（jedis）實(shí)現(xiàn)Session共享的過程

更新時(shí)間：2018年06月07日 14:20:55 作者：Z濤子

這篇文章主要介紹了Spring整合redis（jedis）實(shí)現(xiàn)Session共享,需要的朋友可以參考下

今天來記錄一下自己在整合框架過程中所遇到的問題：

1. 在用redis實(shí)現(xiàn)session共享時(shí)，項(xiàng)目啟動(dòng)報(bào) No bean named 'springSessionRepositoryFilter' is defined 異常

2. 在調(diào)用緩存工具類的時(shí)候顯示注入的JedisPool為Null （一個(gè)跟spring掃描有關(guān)的細(xì)節(jié)錯(cuò)誤）

好了，開始上我整合的文件了

pom.xml依賴jar包

以上是整合的配置文件，其中有關(guān)redis的配置是整合成功的關(guān)鍵

問題總結(jié)

1.之前整合完啟動(dòng)項(xiàng)目報(bào)異常，是因?yàn)榕渲梦募胖玫奈恢脝栴}，以至于啟動(dòng)不成功，多試幾遍，以上的配置文件是可以用的

2.之前調(diào)用緩存工具類，顯示注入JedisPool為空，在controller那邊注入又有值，是因?yàn)槲以赾ontroller那邊調(diào)用工具類的方式是new出來的，所以導(dǎo)致spring在掃描那個(gè)工具類時(shí)丟失Jedispool注入，在controller中改用注入工具類的形式即可解決

例如：
