Spring整合Memcache執行個體，springmemcache執行個體

一、Memcache安裝
：https://github.com/memcached/memcached/releases
官方wiki：https://github.com/memcached/memcached/wiki

啟動參數：
-p 監聽的連接埠
-l 串連的IP地址, 預設是本機
-d start 啟動memcached服務
-d restart 重起memcached服務
-d stop|shutdown 關閉正在啟動並執行memcached服務
-d install 安裝memcached服務
-d uninstall 卸載memcached服務
-u 以的身份運行 (僅在以root啟動並執行時候有效)
-m 最大記憶體使用量，單位MB。預設64MB
-M 記憶體耗盡時返回錯誤，而不是刪除項
-c 最大同時串連數，預設是1024
-f 塊大小增長因子，預設是1.25
-n 最小分配空間，key+value+flags預設是48
-h 顯示協助

二、pom檔案

1 <!-- memcache -->2 <dependency>3     <groupId>com.whalin</groupId>4     <artifactId>Memcached-Java-Client</artifactId>5     <version>3.0.2</version>6 </dependency>

三、設定檔

memcache.properties 檔案

 1 #設定伺服器位址.該連接埠號碼預設為11211 2 memcached.server=192.168.208.131:11211 3 #容錯 4 memcached.failOver=true 5 #設定初始串連數 6 memcached.initConn=20 7 #設定最小串連數 8 memcached.minConn=10 9 #設定最大串連數10 memcached.maxConn=25011 #設定串連池維護線程的睡眠時間12 memcached.maintSleep=300013 #設定是否使用Nagle演算法（Socket的參數），如果是true在寫資料時不緩衝，立即發送出去14 memcached.nagle=false15 #設定socket的讀取等待逾時時間16 memcached.socketTO=300017 #設定串連心跳監測開關18 memcached.aliveCheck=true

memcache.xml 檔案

SockIOPool、MemCachedClient構造器參數poolName需要保持一直，否則會報 attempting to get SockIO from uninitialized pool!

四、測試案例

 1 /** 2  * Mecached測試類別 3  *  4  */ 5 @RunWith(SpringJUnit4ClassRunner.class) 6 @ContextConfiguration(locations = "classpath:application.xml") 7 public class MemcacheTest { 8  9   @Autowired10   private MemCachedClient memCachedClient;11 12   @Test13   public void memCachedGetTest() {14     memCachedClient.set("hello", "123", new Date(System.currentTimeMillis() + 10000L));15     16     System.out.println("hello: " + memCachedClient.get("hello"));17     18     try {19       Thread.sleep(11000);20     } catch (Exception e) {}21     Assert.assertNull(memCachedClient.get("hello"));22     23   }24 }
