Xmemecached的配置如下：
<bean name="memcachedClientBuilder" 
class="net.rubyeye.xmemcached.XMemcachedClientBuilder">
  <constructor-arg>
  <list>
<bean class="java.net.InetSocketAddress">
<constructor-arg>
<value>${xmemcached.ip}</value> 
</constructor-arg>
<constructor-arg>
<value>${xmemcached.port}</value> 
</constructor-arg>
</bean>
</list>
</constructor-arg>
<property name="connectionPoolSize" value="5" /> 
</bean>
<bean name="memcachedClient" factory-bean="memcachedClientBuilder" 
factory-method="build" destroy-method="shutdown">
<property name="opTimeout">
