本文介绍了如何在Linux环境下安装Memcached，并通过Spring框架进行配置和集成。详细展示了applicationContext-memcached.xml文件中配置Memcached连接池参数的方法，以及通过Java代码进行测试的过程。

一、在linux安装memcached，首先按照libevent包，再安装memcached，启动时如果找不到libevent，运行LD_DEBUG=libs /usr/local/memcached/bin/memcached -v，

然后创建软链接ln -s path topath,就可以了启动了。

二、applicationContext-memcached.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"
	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jpa="http://www.springframework.org/schema/data/jpa"
	xsi:schemaLocation="

	default-lazy-init="true">
	
	<context:property-placeholder location="classpath:application.properties"/>
	
	<bean id="memcachedPool" class="com.whalin.MemCached.SockIOPool"
		factory-method="getInstance" init-method="initialize" destroy-method="shutDown">
		<constructor-arg>
			<value>qwe</value>
		</constructor-arg>
		<property name="servers">
		<list>
			<value>${memcache.server}</value>
		</list>
		</property>
		<property name="initConn" value="${memcache.initConn}" />
		<property name="minConn" value="${memcache.minConn}" />
		<property name="maxConn" value="${memcache.maxConn}" />
		<property name="maxIdle" value="${memcache.maxIdle}" /> 
		<property name="maintSleep" value="${memcache.maintSleep}" />
		<property name="nagle" value="${memcache.nagle}" />
		<property name="socketTO" value="${memcache.socketTO}" />
		<property name="socketConnectTO" value="${memcache.socketConnectTO}"/>
	</bean>

	<bean id="cache" class="com.whalin.MemCached.MemCachedClient">
		<constructor-arg>
			<value>qwe</value>
		</constructor-arg>
	</bean>

</beans>

三、application.properties

#memcached configue
memcache.server=127.0.0.1:11211
memcache.initConn=20
memcache.minConn=10
memcache.maxConn=50
memcache.maxIdle=1800000
memcache.maintSleep=3000
memcache.nagle=false
memcache.socketTO=3000
memcache.socketConnectTO=3000

四、测试：

package com.csair.memcached;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.whalin.MemCached.MemCachedClient;
import com.whalin.MemCached.SockIOPool;

public class TestSpring {

	public static void main(String[] args) {
		String path = "applicationContext-memcached.xml";
		ApplicationContext context = new ClassPathXmlApplicationContext(path);
		SockIOPool pool = context.getBean("memcachedPool",SockIOPool.class);
		MemCachedClient cache = context.getBean("cache",MemCachedClient.class);
		cache.add("test", "ppt1");
		System.out.println(cache.get("test"));
	}
}
