spring 集成memcached的详细介绍

前提条件：工程需要引入jar包java_memcached-release_2.0.1.jar

第一步：添加memcached的配置文件。

<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreResourceNotFound" value="false" />
<property name="locations">
<list>
<value>classpath:memcache.properties</value>
</list>
</property>
</bean>

配置文件内容如下：

memcache.server=xxx.xxx.xxx.xxx:11111

memcache.weights=1

memcache.initConn=1

memcache.minConn=1

memcache.maxConn=50

memcache.maintSleep=3000

memcache.nagle=false

memcache.socketTO=3000

第二步：添加memcached的bean管理。

<bean id="memcachedPool" class="com.danga.MemCached.SockIOPool" factory-method="getInstance"
init-method="initialize" destroy-method="shutDown">
<constructor-arg><value>memCachedPool</value></constructor-arg>
<property name="servers"><list><value>${memcache.server}</value></list></property>
<property name="weights"><list><value>${memcache.weights}</value></list></property>
<property name="initConn"><value>${memcache.initConn}</value></property>
<property name="minConn"><value>${memcache.minConn}</value></property>
<property name="maxConn"><value>${memcache.maxConn}</value></property>
<property name="maintSleep"><value>${memcache.maintSleep}</value></property>
<property name="nagle"><value>${memcache.nagle}</value></property>
<property name="socketTO"><value>${memcache.socketTO}</value></property>
</bean>

下面看一下com.danga.MemCached.SockIOPool的源代码，重点是SockIOPool构造函数：

public static synchronized SockIOPool getInstance(String poolName)
{
if (pools.containsKey(poolName))
return pools.get(poolName);

SockIOPool pool = new SockIOPool();
pools.put(poolName, pool);

return pool;
}

<bean id="memCacheClient" class="com.danga.MemCached.MemCachedClient">
<constructor-arg><value>memCachedPool</value></constructor-arg>
</bean>

下面看一下com.danga.MemCached.MemCachedClient的源代码，重点是MemCachedClient的构造函数：

public MemCachedClient(String poolName)
{
this.poolName = poolName;
init();
}

第三步：测试memcached的功能。

public class MemcacheTest {
public static void main(String[] args)
{
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
MemCachedClient memCachedClient=(MemCachedClient)context.getBean("memCacheClient");
memCachedClient.set("hello", "swiftlet");
memCachedClient.get("hello");
}
}
