我正在使用EhCache开发一个简单的缓存功能.有一个通用基类实现我的缓存接口(BECache):

public class EhCacheBase<K, V> implements BECache<K, V> {

private static CacheManager cacheManager;
private String cacheName;

public EhCacheBase(String cacheName) {
    this.cacheName = cacheName;
}

public void cache(K key, V value) {
    Cache cache = cacheManager.getCache(cacheName);
    if (cache == null) {
        throw new NullPointerException("Failed to obtain cache: " + cacheName);
    }
    Element element = new Element(key, value);
    cache.put(element);
}

目的是将缓存定义如下:

public class ObjectCache extends EhCacheBase<String, Object>{

    public ObjectCache (String cacheName) {
       super(cacheName);
    }
}

假设'cacheName'在ehcache.xml中定义,我得到了一个用于缓存某些对象的好类.

我正在尝试为'EhCacheBase.cache(...)'方法编写一个测试,以确保检索缓存并放置一个值(使用Mockito):

private static final String CACHE_NAME …
