       (1)并不是所有有用的模块都必须转化成Bean．Bean主要是能被用来可视化操作去完成一些效果．
       (2)类库是一个提供函数操作给编程者的一个有效操作,但是并不能从可视化操作中来获益.
       (3)举个例子来说：提供JDBC数据库访问的API作为一个类库比作为一个bean要好，因为JDBC的核心是用一个可编程的API,并不是能够直接展现于可视化操作．然而，写一个数库库访问Bean在JDBC的顶层还]]>https://blog.youkuaiyun.com/banqingyang/article/details/6209853https://blog.youkuaiyun.com/banqingyang/article/details/6209853banqingyangSat, 26 Feb 2011 15:39:00 +0800Query上有list()與iterator()方法，兩者的差別在於list()方法在讀取資料時，並不會利用到缓存，而是直接再向数据庫查詢，而iterator()則將讀取到的資料寫到缓存，並於讀取時再次利用。]]>https://blog.youkuaiyun.com/banqingyang/article/details/6209852https://blog.youkuaiyun.com/banqingyang/article/details/6209852banqingyangSat, 26 Feb 2011 15:39:00 +0800==的理解：
