今天又被groovy的高效吓到了。

想提取所有的itemCodes，两种玩法

一、常规方法：遍历组装

RestResult items = getListPager()
    def temp = []
    items.data.data.each {
         temp.push(it.itemCode)
    }

println(temp)

\[DP180929155952858, DP180511114211610, DP1539683378800, DP1539682576227, DP1539681917164, DP1539681882632, DP1539681460929, DP1539681297697, DP1539679354755\]

二、直接拿值，简直不能再高效了

RestResult items = getListPager()
    def itemCodes = items.data.data.itemCode
    println(itemCodes)

\[DP180929155952858, DP180511114211610, DP1539683378800, DP1539682576227, DP1539681917164, DP1539681882632, DP1539681460929, DP1539681297697, DP1539679354755\]
