开始以为配置了这个文件就可以了，搞了半天还是没生效，不能转驼峰，然后查了下configuration初始化时它的值也为true，说明初始化是正确，后来才知道原因出在mapper文件

[*]<mapper namespace="menu.mysql">
[*] <select id="selectMenu" resultType="org.me.menu.Menu">
[*] select MENU_ID, MENU_NAME, PARENT_ID, URL, TITLE, LEAF, ORDER_SEQ

[*] order by ORDER_SEQ
[*] </select>
[*]</mapper>
开始我配置成resultType="hashMap"是可以返回结果，但是结果是没有自动转成驼峰，要真正存在一个与它对应的驼峰Bean与它对应才生效，resultType="org.me.menu.Menu"
