tomcat7.055、redis2.8、jedis.jar、common-pool2.2.jar、tomcat-redis–session-manager-1.2-tomcat-7.jar

将上面的3个jar包放入tomcat下的lib目录

修改content.xml

添加：

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

启动tomcat时，报错，无法成功启动tomcat。

以下是错误日志：

在新加入的3个jar包中，均没有需要用到org.apache.commons.pool.impl.GenericObjectPool$Config的地方，redis引用的是

org.apache.commons.pool2.impl.GenericObjectPool$Config，不知道怎么会出现这个错。

在tomcat-redis–session-manager-1.2-tomcat-7.jar的源码中有一个类RedisSessionManager在Eclipse中发现有问题。

这个类中有处代码for (Valve valve : getContext().getPipeline().getValves()) 这里的getContext() 方法报错，提示没有该方法，并且在该类的父类ManagerBase中也没有找到该方法。
