问题描述：

本人在使用idea搭建项目的时候，首先搭建ssm项目，然后将ssm项目拆分为多模块项目，再添加多数据源，添加完多数据源后再添加redis，然后使用eureka作为注册中心，使用springcloud做微服务。再昨天下午的搭建过程都是挺顺利的，经过几天的努力也算是完成了，可是昨天临走前把电脑关闭，今天早上再打开电脑的时候，突然发现服务方起不来了，w*f*，查看了错误发现貌似是jar包冲突问题，经过一阵排查发现是spring-data-redis的jar包和redis客户端的jar包冲突（为啥昨天能起来呢，到现在我都还整不明白。。。）
不说了，先看报错信息：

jar包冲突问题就是这么恶心，我明明知道是这俩（spring-data-redis /redis）jar包冲突，可是却找不到正确的版本（第一次用springboot和maven），最后在这篇博客中发现了蛛丝马迹：http://zhaobing315.iteye.com/blog/2082189， 这个博客里又提到了这个国外网友的问题：google结果链接：http://stackoverflow.com/questions/22704518/jedispoolconfig-is-not-assignable-to-genericobjectpoolconfig 最后看到这俩货的版本号为：
so，大家都看到了，分别是1.2.1和2.4.2，然后我将这俩货版本号修改正确，项目完美启动！！！
在这里做个总结，希望能够帮助大家！！！！
