问题：从模板中推导出正确的json结构

test1.vm

#set($orderList = $!{result.orderList})
#foreach($order in $!orderList)
  #set($shop = $!{order.shop})
  $!{shop.singleItemId}
#end

test2.json

{
  "result": {
    "orderList": [
      {
        "shop": {
          "singleItemId": ""
        }
      }
    ]
  }
}

挺爷加油。。。。
