在使用tomcat + redis 来处理分布式 session 的时候，需要以下的包：

commons-pool-1.5.4.jar

commons-pool2-2.0.jar

jedis-2.2.0.jar

tomcat-redis-session-manager-1.2-tomcat-7.jar （[其他包都可以maven里面找，这个比较不好找，点击这里下载][maven]）

tomcat-util.jar

但是部署好启动tomcat的时候报异常：

严重: Begin event threw error

原因是因为你使用的 jedis 的jar包版本太高，如2.7以上，更换这个包为jedis-2.2.0.jar ， 重启启动，就不会报错了。
