一個EHCACHE簡單使用例子

Ehcache 是現在最流行的純Java開源緩存框架，配置簡單、結構清晰、功能強大，最初知道它，是從Hibernate的緩存開始的。網上中文的EhCache材料以簡單介紹和配置方法居多，如果你有這方面的問題，請自行google；

簡單的例子如下；

EhCache.java

package com.mybean;

import java.io.Serializable;
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;

public class EhCache {
    public static void main(String[] args) {
        System.out.println(1);
        // CacheManager manager = new CacheManager();
        //創建一個緩存管理器
        CacheManager singletonManager = CacheManager.create();
        //建立一個緩存實例
        Cache memoryOnlyCache = new Cache("testCache", 5000, false, false, 5, 2);
        //在內存管理器中添加緩存實例
        singletonManager.addCache(memoryOnlyCache);
        Cache cache = singletonManager.getCache("testCache");
        //使用緩存
        Element element = new Element("key1", "value1");
        cache.put(element);
        cache.put(new Element("key1", "value2"));

        element = cache.get("key1");
        Serializable value = element.getValue();
        System.out.println(value);

        int elementsInMemory = cache.getSize();
        System.out.println(elementsInMemory);

        long elementsInMemory2 = cache.getMemoryStoreSize();
        System.out.println(elementsInMemory2);

        Object obj = element.getObjectValue();
        cache.remove("key1");
        System.out.println(obj);
        singletonManager.shutdown();
        // manager.shutdown();
        System.out.println(2);
    }
}
