Collections Groovy GroupBy字段，带空格和不带空格

我有发票清单如下

def invoices = [
'LEDES98BI V2',
'LINE|INVOICE_DATE|INVOICE_NUMBER|INVOICE_TOTAL',
'1|20150301|INV-Error_Test1|22',
'2|20150301|INV-Error_Test1|24',
'3|20150301|INV-Error_Test2|26',
'4|20150301|INV-Error_Test2|28,']

我试图在上面的集合中使用

INVOICE\u NUMBER

进行分组，并尝试使用

INVOICE\u NUMBER

和行作为值实现映射，下面的代码就是这样做的

def lines = invoices*.split('\\|').findAll{ it.size()>1 }
def heads = lines.first()
def invoiceMap =  lines.tail().collect{ [heads, it].transpose().collectEntries() }.groupBy{ it.INVOICE_NUMBER }

如果我打印

invoiceMap

我会得到我想要的地图

 [INV-Error_Test1:[[LINE:1, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test1, INVOICE_TOTAL:22], 
                   [LINE:2, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test1, INVOICE_TOTAL:24]], 
  INV-Error_Test2:[[LINE:3, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test2, INVOICE_TOTAL:26], 
                   [LINE:4, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test2, INVOICE_TOTAL:28,]]
  ]

---

但是如果

INVOICE\u编号

在

invoices

映射中有任何空格，则我的代码不起作用。有人能帮我在发票号上用空格写代码吗？

你只需要引用你的名字，就像这样

def invoiceMap=lines.tail（）.collect{[heads，it].transpose（）.collectEntries（）}.groupBy{it.'INVOICE NUMBER'}

使用合适的CSV解析器，而不是自己滚动

@Grab('com.xlson.groovycsv:groovycsv:1.0')
import static com.xlson.groovycsv.CsvParser.parseCsv

def invoices = [
'LEDES98BI V2',
'LINE|INVOICE_DATE|INVOICE_NUMBER|INVOICE_TOTAL',
'1|20150301|INV-Error_Test1|22',
'2|20150301|INV-Error_Test1|24',
'3|20150301|INV-Error_Test2|26',
'4|20150301|INV-Error_Test2|28,']

def data = parseCsv(invoices.drop(1).join('\n'), separator:'|')
def invoiceMap = data.collect().groupBy { it.INVOICE_NUMBER }

或在列标题中加空格：

def invoices = [
'LEDES98BI V2',
'LINE|INVOICE_DATE|INVOICE NUMBER|INVOICE_TOTAL',
'1|20150301|INV-Error_Test1|22',
'2|20150301|INV-Error_Test1|24',
'3|20150301|INV-Error_Test2|26',
'4|20150301|INV-Error_Test2|28,']

def data = parseCsv(invoices.drop(1).join('\n'), separator:'|')
def invoiceMap = data.collect().groupBy { it.'INVOICE NUMBER' }

只是为了确保我们谈论的是同一件事，哪一件不起作用？列标题中的空格（使用

发票编号

而不是

发票编号

）？或列值中的空格（

2015 03 01

而不是

20150301

）？列标题中的空格（使用发票号和一些空格代替发票号）
