文章の内容を抜粋します.http://www.cnblogs.com/linjiqin/archive/2011/03/28/1998125.html
creator=「spring」は、作成対象の方式を「spring」が管理すると説明しています.
<param name=「beanName」value=「deptServices」>
springで作成するクラスの名前を表します.「deptServices」に基づいてspringを一意に識別するプロファイルを検索して、対応する関係を形成します.
<convert match=「entity.*」converter=「bean」
ここでconvert="bean"は、伝達の対象と戻るオブジェクトの変換を説明するためにbeanを使用する方法であり、この中の値は変わらない.
