诡异的是，在MyEclipse里运行一定会出这个问题，但是项目打包成jar在外部运行是没这个问题的。
当时找了很久的答案，包括国外的网站都去看过了，一般都是说spring、jedis、和commons-pool2的版本配合问题。
然而折腾了很久觉得还真不是，因为试了很多版本都不对。
然后怒而改代码，发现无法拉起，于是考虑jar包的加载顺序问题。
用的是Spring 3.1.4版本，Jedis 2.9版本， commons-pool2 2.6.0版本。
在Order and Export里，将Jedis和commons-pool2放在spring一系列的jar包之前，编译，启动，错误消失，问题解决
