XMemcached与Spring3.2缓存框架集成.docx

从Spring3.1开始，增加了抽像缓存框架，利用Spring3.1提供的注释，可以很方便的使用缓存，Spring官方给出基于Map和EHCache的实现，正好最近在用Memcached，参考了EHCacheCacheManager的源码，写了一个基于XMemcached的MemcachedCacheManager。直接上代码(注：只支持Spring3.2以上版本)?1、MemcachedCacheManager.javapublic class MemcachedCacheManager extends AbstractTransactionSupportingCacheManager{private ConcurrentMapString, Cache cacheMap = new ConcurrentHashMapString, Cache();private MapString, Integer expireMap = new HashMapString, Integer();private MemcachedClient memcachedClient;public MemcachedCacheManager(){}@Overrideprotected Collection? extends Cache loadCaches(){CollectionCache values = cacheMap.values();return values;}@Overridepublic Cache getCache(String name){Cache cache = cacheMap.get(name);if (cache == null){Integer expire = expireMap.get(name);if (expire == null){expire = 0;expireMap.put(name, expire);}cache = new MemcachedCache(name, Value(), memcachedClient);cacheMap.put(name, cache);}return cache;}public void setMemcachedClient(MemcachedClient memcachedClient){this.memcachedClient = memcachedClient;}public void setConfigMap(MapString, Integer configMap){this.expireMap = configMap;}}?2、MemcachedCache.java?public class MemcachedCache implements Cache{private final String name;private final MemcachedClient memcachedClient;private final MemCache memCache;public MemcachedCache(String name, int expire, MemcachedClient memcachedClient){ = name;this.memcachedClient = memcachedClient; this.memCache = new MemCache(name, expire, memcachedClient);}@Overridepublic void clear(){memCache.clear();}@Overridepublic void evict(Object key){memCache.delete(key.toString());}@Overridepublic ValueWrapper get(Object key){ValueWrapper wrapper = null;Object value = memCache.get(key.toString());if (value != null){wrapper = new SimpleValueWrapper(value);}return wrapper;}@Overridepublic String getName(){return ;}@Overridepublic MemcachedClient getNativeCache(){return this.memcachedClient;}@Overridepublic void put(Object key, Object value){memCache.put(key.toString(), value);}}
