Spring集成memcached的详细介绍

本文转载自:  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。

1 2 3 4 5 6 7 8 9 10

< 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。

1 2 3 4 5 6 7 8 9 10 11 12

< 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：

1 2 3 4 5 6 7 8 9 10

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 ; }

1 2 3

< 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：

1 2 3 4 5

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

第三步：测试memcached的功能。

1 2 3 4 5 6 7 8 9

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" ) ; } }
