我正在尝试创建一个新的 Map <String, List<String>> headErrors具有来自另一个的选择性元素Map <String, List<String>> invoiceErrorLines
invoiceErrorLines = ['1660277':['Line : 1 Invoice does not foot Reported', 'Line : 2 MATH ERROR'],
'1660278':['Line : 5 Invoice does not foot Reported', 'cl_id is a required field'],
'1660279':['Line : 7 could not parse date ', 'File Error : The file doesnt have delimiter'],
'1660280':['Line : 9 Invoice error']]
def regex = "^Line\\s(?:(\\d+)\\s)?\\s*:\\s+(\\d+)?.+"
def headErrors = invoiceErrorLines.each{ inv ->
inv.value.findAll{it.contains('Invoice does not foot Reported') || !(it ==~ regex) }.groupBy{inv.key}
}
新 map 应包含发票号码作为键及其相应的错误消息，与 regex = "^Line\\s(?:(\\d+)\\s)?\\s*:\\s+(\\d+)?.+" 不匹配但包含Invoice does not foot Reported
当我打印headErrors时我看到与 invoiceErrorLines 相同的 map 但
我期待 headErrors如下
headErrors = ['1660277':['Line : 1 Invoice does not foot Reported'],
'1660278':['Line : 5 Invoice does not foot Reported', 'cl_id is a required field'],
'1660279':['File Error : The file doesnt have delimiter']
]
有人可以帮我解决这个问题吗？
最佳答案
与
def headErrors = invoiceErrorLines.collectEntries{ key, value ->
value.findAll{ it.contains('Invoice does not foot Reported') || !(it ==~ regex) }.groupBy{ key }
}
它的产量
[1660277:[Line : 1 Invoice does not foot Reported], 1660278:[Line : 5 Invoice does not foot Reported, cl_id is a required field], 1660279:[File Error : The file doesnt have delimiter]]
