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页面里面把public_user_id这样的字符串转换成：publicUserId形式。

查找多方资料，得出上面代码，记录一下，供人参考。
