第一步：安装Memcached 服务端
1、CentOs(6.4)服务器安装Memcached 服务端（可以查看：cenos 6.4 安装memcached 服务端）
2、下载java版客户端 java_memcached-release_2.6.1.zip
3、CentOs(6.4)服务器启动Memcached 服务端

java_memcached-release_2.6.6.jar第二步：配置memcached.properties文件
memcache.server=120.25.56.93:11211
memcache.initConn=20
memcache.minConn=10
memcache.maxConn=50
memcache.maintSleep=3000
memcache.nagle=false
memcache.socketTO=3000 第三步：spring配置文件集成memcached
