一個簡單的 ehcache 操作封裝

CacheWrapper.java

public interface CacheWrapper<K, V>
{
  void put(K key, V value);

V get(K key);
}</pre> 


 EhcacheWrapper.java 

import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Ehcache;
import net.sf.ehcache.Element;

public class EhcacheWrapper<K, V> implements CacheWrapper<K, V> 
{
    private final String cacheName;
    private final CacheManager cacheManager;

public EhcacheWrapper(final String cacheName, final CacheManager cacheManager)
{
    this.cacheName = cacheName;
    this.cacheManager = cacheManager;
}

public void put(final K key, final V value)
{
    getCache().put(new Element(key, value));
}

public V get(final K key) 
{
    Element element = getCache().get(key);
    if (element != null) {
        return (V) element.getValue();
    }
    return null;
}

public Ehcache getCache() 
{
    return cacheManager.getEhcache(cacheName);
}
