tomcat配置tomcat-redis-session-manager

今天写了半天程序，有点乏了。想想来配置一下tomcat-redis-session-manager吧，但是按照 官方文档配了总是tomcat启动错误。 

?

1	java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool$Config

google了半天终于找到了解决办法，现记录如下。 
出现上面错误的原因其实很明显，只是我太粗心了，没有找到类。 
当然首先下载所需的包了： 

Commons-Pool   Jedis   tomcat-redis-session-manager 

将这些jar包都丢到tomcat的lib目录下，然后配置context.xml了，将如下内容添加到context.xml中 

?

1 2 3 4 5 6

<Valve className="com.radiadesign.catalina.session.RedisSessionHandlerValve" /> <Manager className="com.radiadesign.catalina.session.RedisSessionManager"          host="localhost" <!-- optional: defaults to "localhost" -->          port="6379" <!-- optional: defaults to "6379" -->          database="0" <!-- optional: defaults to "0" -->          maxInactiveInterval="60" <!-- optional: defaults to "60" (in seconds) --> />

Value字段需要出现在Manager字段之前，然后启动你的tomcat，在redis-server控制台上就可以看到如下信息了

忘了说了，tomcat-redis-session-manager不支持tomcat 7.x，tomcat 7.x的支持还在努力中啊，所以如果要用的话，请使用tomcat 6.x
