1、添加pom依赖
<dependencies>
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>spring-cache</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>xmemcached-provider</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>simple-spring-memcached</artifactId>
<version>4.0.0</version>
</dependency>
</dependencies>2、创建memcached.properties
#simple memcached config
simple.memcache.server=127.0.0.1:12000
simple.memcache.consistenthashing=true
simple.memcache.connectionpoolsize=1
simple.memcache.optimizeget=false
simple.memcache.optimizemergebuffer=false
simple.memcache.mergefactor=50
simple.memcache.usebinaryprotocol=true
simple.memcache.connectiontimeout=3000
simple.memcache.operationtimeout=2000
simple.memcache.enableheartbeat=true
simple.memcache.failureMode=false3、创建memcached-simple.xml文件
<?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:cache="http://www.springframework.org/schema/cache"

default-autowire="byName">
<!-- =================================== 配置Memcached =============================== -->

<import resource="classpath:simplesm-context.xml" />
<aop:aspectj-autoproxy />
<context:annotation-config />
<bean name="defaultMemcachedClient" class="com.google.code.ssm.CacheFactory">

</bean>
</property>
<property name="configuration">
<bean class="com.google.code.ssm.providers.xmemcached.XMemcachedConfiguration">
<property name="consistentHashing"><!--consistentHashing属性定义了缓存节点的查找方法: 是否使用哈希 -->
<value>${simple.memcache.consistenthashing}</value>
</property>
<property name="connectionPoolSize">
<value>${simple.memcache.connectionpoolsize}</value>
</property>
<property name="optimizeGet">
<value>${simple.memcache.optimizeget}</value>

<property name="optimizeMergeBuffer">

</property>
<property name="failureMode">

</property>
</bean>
</property>
<!-- 该Memcached配置的Cache名称 一个应用中存在多个Memcached时，各个配置的cacheName必须不同。如果该值未设，系统默认为default -->
<property name="cacheName" value="default" />
</bean>
<bean class="com.google.code.ssm.Settings"><!-- 这玩意儿在3.2 后，文档可以指定顺序 以及 拦截器 前后执行 - -！暂时没用过，加上不报错 -->
<property name="order" value="500" />
</bean>
</beans>4、创建spring-context.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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:cache="http://www.springframework.org/schema/cache"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/tx

http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/cache
http://www.springframework.org/schema/cache/spring-cache-4.0.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd"
default-autowire="byName">
<context:property-placeholder location="classpath*:properties/memcached.properties"/>
<context:annotation-config />
<context:component-scan base-package="io.mykit.cache.spring" />
<aop:config proxy-target-class="true"/>
<!-- <import resource="classpath:memcached/memcached.xml"/> -->
<import resource="classpath:memcached/memcached-simple.xml"/>
</beans>5、编写使用注解的类
/**
* 根据订单号获取订单信息
* @param orderNum
* @return
*/
@ReadThroughSingleCache(namespace = "test", expiration = 30000)
public Order getOrder(@ParameterValueKeyProvider String orderNum) {
System.out.println("缓存没有命中");
return this.orderDao.getOrder(orderNum);
}注意： @ReadThroughSingleCache(namespace = "test", expiration = 30000) 中的expiration单位是秒！！
就是这么简单，如果大家想了解simple-spring-memcached其他的注解，可参考博文《Memcached之——simple-spring-memcached-3.0.x 注解详解》
