直接上代码，干货:
import java.util.HashMap; import java.util.Map; /** * map缓存 * @author ming * * @param <K> * @param <V> */ public class MapDataCache { private static Map<String, Object> cacheMap; public static Object getCache(String key, Object defaultValue) { Object obj = getCacheMap().get(key); return obj==null?defaultValue:obj; } public static void putCache(String key, Object value) { getCacheMap().put(key, value); } public static void removeCache(String key) { getCacheMap().remove(key); } public static Map<String, Object> getCacheMap() { if (cacheMap==null){ cacheMap = new HashMap<String, Object>(); } return cacheMap; } }
