使用Hibernate的Ehcache搜索API

Question

我可以使用ehcache搜索API搜索二级缓存吗？

如果我使用put()方法直接用对象填充缓存，则可以使用SearchAttribute进行搜索。当我试图查询二级Hibernate缓存时，我坚持在ehcache中从一个对象的反汇编状态组装一个实体。

    public class TestExtr implements AttributeExtractor {

    @Override
    public Object attributeFor(Element element, String arg1)
            throws AttributeExtractorException {

        return element.?()  ; //how to cast its value to Employee?
    }
}

我的实体示例

      public class Employee implements Serializable {
        private int id;
        private String firstName;
        private String lastName;
        private int salary;

   // getters and setters
    }

二级缓存的

Element element值为：

org.hibernate.cache.ehcache.internal.strategy.AbstractReadWriteEhcacheAccessStrategy$Item@6b8efd7c 
    key = test.Employee#1383    
    CacheEntry(test.Employee)[aaaaa,dd,77]
