然后一直启动还是报错，以为是版本号问题，试了几个不同版本似乎没有变化，于是尝试退出idea并清除缓存。重新打开idea，等待加载完成，启动不报错了，OK问题解决。尝试了下，在maven里面添加了上面的依赖。然后点击通义灵码工具问了下，回答是缺少。

多引用几个JAR包 jedis-2.1.0.jar spring-data-redis-1.0.2.RELEASE.jar 只引入这两个的话,估计也会报上面的那个错,所以下面的两个也要引入 commons-pool-1.5.5.jar commons-pool2-2.2.jar 点击打开链接

原因：缺少commons-pool-X.jar包，到http://commons.apache.org/proper/commons-pool/download_pool.cgi下载后引入即可（地址可能失效，请自行Google）。 转载于:https://www.cnblogs.com/Richard-xie/p/3445800.html...
