Spring集成Memcached三种方式

Memcached Client目前有3种：
Memcached Client for Java
SpyMemcached
XMemcached
这三种Client一直存在各种争议：
Memcached Client for Java 比 SpyMemcached更稳定、更早、更广泛；
SpyMemcached 比 Memcached Client for Java更高效；
XMemcached 比 SpyMemcache并发效果更好。
方式一：Memcached Client for Java
jar包准备：java_memcached-release_2.6.6.jar
memcached.properties配置文件：配置服务器地址，连接数，超时时间等
配置Bean
将app-context-memcached.xml配置到app-context.xml中
Memcached工具类：
测试：
方式二：SpyMemcached
jar包准备：spymemcached-2.10.3.jar
spymemcached.properties配置文件：
app-context-spymemcached.xml配置bean:
SpyMemcachedManager 工具类：
测试：
方式三：XMemcached
jar包准备：xmemcached-1.4.1.jar
xmemcached.properties配置文件：
