HDC调试需求开发（15万预算）,能者速来！>>>
问题是这样的
我想把下面的book对像（含Factory属性）使用缓存ehcache缓存起来，但是总是报错，相信是我的使用方式不对，或是此路不通吧，有没有什么好的办法可以实现这样的想法呢，多谢了
public class Factory { private String Address; public Factory(String address) { super(); Address = address; } public String getAddress() { return Address; } public void setAddress(String address) { Address = address; } }



public class Book implements Serializable { private String bookName; private Factory factory; public Factory getFactory() { return factory; } public void setFactory(Factory factory) { this.factory = factory; } public Book(String bookName) { this.bookName = bookName; } public String getBookName() { return bookName; } }
Ehcache使用方法

CacheManager manager1 = new CacheManager(); String[] cacheNamesForManager1 = manager1.getCacheNames(); Cache cache = manager1.getCache("sampleCache1"); Book b = new Book("Music Book"); b.setFactory(new Factory("china")); Element element1 = new Element("book", b); cache.put(element1);
