java – Ehcache丢失对象

我正在使用Ehcache来缓存在我的应用程序中加载非常昂贵的对象.在启动时,我会缓存所有需要的对象,并且每天通过一个单独的进程刷新一次.

但是,似乎在我将对象添加到缓存后不久,它们就消失了.没有任何东西被报告为被驱逐,但由于某种原因,对象不会在缓存中持续存在.当我运行ObjectLoader.loadCache()时,这是我收到的输出：

我是否配置了错误的ehcache,或者我的代码中是否有错误？任何帮助,将不胜感激.谢谢.

我使用的是spring 3.1.0,ehcache-spring-Annotations 1.1.2和ehcache 2.4.2

ObjectCacheFacade.java

@Component()
public class ObjectCacheFacade {
    private static final String CACHE_KEY = "myObjectCache";

    @resource
    private CacheManager cacheManager;
    private Cache cache;

    public ObjectCacheFacade() {
        cacheManager = CacheManager.geTinstance();
        this.cache = cacheManager.getCache(CACHE_KEY);
    }

    public Object getObjectFromCache(String objectId) {
        Object result = null;
        Element element = cache.get(objectId);

        if (element != null && element.getValue() != null) {
            result = element.getObjectValue();
        } 

        return result;
    }

    public void putObjecTintoCache(String objectId,Object object) {
        Element element = new Element(objectId,object);
        cache.put(element);
    }

    public int getSize() {
        return cache.getSize();
    }

    public void removeObjectFromCache(String objectId) {
        cache.remove(objectId);
    }

    public void flushCache() {
        cache.removeAll();
    }

    public Cache getCache() {
        return cache;
    }
}
