项目中需要用到缓存，经过比较后，选择了redis，客户端使用jedis连接，也使用到了spring提供的spring-data-redis。配置正确后启动tomcat，发现如下异常：

非常奇怪，由于google的访问限制，百度了半天也没什么结果，我就知道google一定可以的，果断FQ搜索，果然没有让我失望，
google结果链接：http://stackoverflow.com/questions/22704518/jedispoolconfig-is-not-assignable-to-genericobjectpoolconfig
看情况应该是jar包版本问题，我目前的版本为：jedis-2.1.0.jar + spring-data-redis-1.3.0.RELEASE.jar。
按照提示我将jedis升级成了jedis-2.4.2.jar。
再次运行，成功！！
哎，百度，不争气啊
