前提条件：在阿里云已购买缓存服务器

1、引入缓存机制需要的jar包： spymemcached-2.11.4.jar

2、xml配置：

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    	                    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
    	                    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
    
    	<bean id="authdescriptor" class="net.spy.memcached.auth.AuthDescriptor">
    		<constructor-arg index="0">
    			<array value-type="java.lang.String">
    				<value>PLAIN</value>
    			</array>
    		</constructor-arg>
    		<constructor-arg index="1" ref="plaincallbackhandler"></constructor-arg>
    	</bean>
    
    	<bean id="plaincallbackhandler" class="net.spy.memcached.auth.PlainCallbackHandler">
    		<constructor-arg index="0" value="缓存服务器用户名"></constructor-arg>
    		<constructor-arg index="1" value="缓存服务器密码"></constructor-arg>
    	</bean>
    
    	<bean id="connectionfactorybuilder" class="net.spy.memcached.ConnectionFactoryBuilder" 
    		init-method="build">
    		<property name="opFact" ref="binaryoperationfactory"></property>
    		<property name="authDescriptor" ref="authdescriptor"></property>
    	</bean>
    	<bean name="connectionfactory" factory-bean="connectionfactorybuilder" factory-method="build"/>
    	 
    	<bean id="binaryoperationfactory"
    		class="net.spy.memcached.protocol.binary.BinaryOperationFactory">
    	</bean>
    
    	<bean id="asciioperationfactory"
    		class="net.spy.memcached.protocol.ascii.AsciiOperationFactory">
    	</bean>
    	
    	<bean name="addrutil" class="net.spy.memcached.AddrUtil"
    		factory-method="getAddresses">
    		<constructor-arg>
    			<value缓存服务器地址(形式：ip:port)</value>
    		</constructor-arg>
    	</bean>
    
    	<bean id="memcachedclient" class="net.spy.memcached.MemcachedClient">
    		<constructor-arg index="0" ref="connectionfactory"></constructor-arg>
    		<constructor-arg index="1" ref="addrutil"></constructor-arg>
    	</bean>
    </beans>

3、代码调用：

// 新增缓存，key为缓存的key，timeOut为缓存的失效时间，单位为秒，object为缓存value
    memcachedClient.set(key, timeOut, object);
    
    // 根据key获取缓存数据
    memcachedClient.get(key);
    
    // 清除所有缓存
    memcachedClient.flush();
    
    // 删除指定缓存
    memcachedClient.delete(key);
