java - CompositeCacheManager.getUnconfiguredInstance() API 使用

Question

下面是我的课的样子。

import org.apache.jcs.JCS;
import org.apache.jcs.access.exception.CacheException;
import org.apache.jcs.engine.control.CompositeCacheManager;

private JavaCacheUPKStore(Connection conn) {
    props.put("jcs.default", "");
    props.put("jcs.default.cacheattributes",
                "org.apache.jcs.engine.CompositeCacheAttributes");
    props.put("jcs.default.cacheattributes.MaxObjects",
                maxObjects.toString());
    props.put("jcs.default.cacheattributes.MemoryCacheName",
                "org.apache.jcs.engine.memory.lru.LRUMemoryCache");
    props.put("jcs.default.cacheattributes.UseMemoryShrinker", "false");
    CompositeCacheManager.getUnconfiguredInstance();

}

我的项目中存在 jcs-1.3.jar 并且在执行项目时低于异常。无法初始化类 org.apache.jcs.engine.control.CompositeCacheManager
