Velocity操作字符串

<resultMap id="BaseResultMap" type="${bussPackage}.entity.${entityPackage}.$!{className}">
		#foreach($item in $!{columnDatas})
			#set ($columnName = $item.columnName)
			#set ($columnArray = $columnName.split("_"))
			#set ($camelColumnName = "")
			#foreach($word in $!{columnArray})
				#set ($camelColumnName = $camelColumnName + $word.substring(0,1).toUpperCase() + $word.substring(1,$word.length()))
			#end
			#set ($camelColumnName = $camelColumnName.substring(0,1).toLowerCase() + $camelColumnName.substring(1,$camelColumnName.length()))
		<result column="$!item.columnName" property="$camelColumnName" />
		#end
	</resultMap>

在velocity頁面裏面把public_user_id這樣的字符串轉換成：publicUserId形式。

查找多方資料，得出上面代碼，記錄一下，供人蔘考。
