将附件中的两个包放入tomcat的lib 目录下

用新版本的测试还有点问题java.lang.IllegalArgumentException: No node found for key bak，使用原来的1.4的版本正常
2. 修改tomcat的server.xml配置（在Host节点之间添加如下配置）：

<Context path="" docBase="/app/wap/server/sns">
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:192.168.169.47:11212 n2:192.168.169.47:11213"
failoverNodes="n2"
sticky="false"
requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.JavaSerializationTranscoderFactory" />
</Context>
