// conf.common().add(new TransparentActivationSupport());
// conf.blockSize(int):这个可以配置Db4o文件的大小，参数范围为1-127,默认的是1,也就是默认的最大文件为2G,官方推荐的配置为8,正好是一个指针的长度，这样有利于加快速度
// conf.activationDepth(int):这个是设置激活的深度，默认值是5,即当使用链表结构的时候最得首对象后最多只能往下走5层，这是为了不浪费内存
// conf.lockDatabaseFile(true|false):默认值是true，即默认情况下是锁定数据库的，一个数据库文件只允许被一个应用程序读取，如果需要可以把它设为false，这样就能够允许多程序共享一个数据库了
// conf.unicode(true|false):默认值是true，即默认是采用unicode编码的。采用unicode的好处是支持多国语言，不好的地方是速度变慢，如果没用中文或者为了速度起见，可以把它关闭
// conf.weakReference(true|false):默认是true，即默认为持有一份对象的本地缓存，好处是使操作更快，缺点是一占内存，二如果要获得别人已经commit的对象要手动refresh一下
