tomcat7使用redissession后启动报错，加了这几个jar包
commons-pool-1.6.jar
commons-pool2-2.2.jar
jedis-2.4.2.jar
tomcat-redis-session-manager-1.2-tomcat-7-java-7.jar

配置如下
<Valve className="com.radiadesign.catalina.session.RedisSessionHandlerValve"/>
<Manager className="com.radiadesign.catalina.session.RedisSessionManager"
host="192.168.10.235"
port="6379"
database="0"
maxInactiveInterval="60"/>
