Groovy 正在打印地图<String,List<Map<String,String>>> 数据

Question

我有Map<String,List<Map<String,String>>> invoices如下

invLineItems = [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,]]]

我正在尝试打印如下

println " INV-Error_Test2 Details "
invLineItems.get('INV-Error_Test2').each{ 
    it.each{
print "LINE = "+ it['LINE'] 
    }
 }

并且低于错误 groovy.lang.MissingPropertyException: No such property: LINE for class: java.util.LinkedHashMap$Entry

有人可以帮我打印这些数据吗？

注意：实际上我总共有 24 个 headers，但为了使问题简单化，我刚刚发布了 4 个 headers(Line, Invoice_Date,Invoice-Number,Invoice_Total) 并且我只尝试打印几个 headers 共 24

更新：我正在尝试用下面的发票错误更新 Map<String,List<Map<String,String>>> invoices

InvoiceError // is an entity with below attributes
{ String errorMessage,
  String invoiceNumber    
}
ErrorMessage                                          invoiceNumber   
-------------                                       -------------------     
File Error : The file is in an unsupported format   INV-Error_Test1
Line : 1 Invoice does not foot Reported             INV-Error_Test1
Line : 2 MATH ERROR                                 INV-Error_Test1
Line : 3 MATH ERROR                                 INV-Error_Test2
Line : 3 Invoice does not foot Reported             INV-Error_Test2

我正在努力实现下面的地图如果错误消息没有行号，则需要在顶层附加为 invLineItems.put('error',['INV-Error_Test1' :文件错误：文件格式不受支持]) 否则应将错误消息附加到匹配的发票和行号，如下所示

invLineItems = [INV-Error_Test1:[[LINE:1, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test1, INVOICE_TOTAL:22, error : `Line : 1 Invoice does not foot Reported`], 
                                [LINE:2, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test1, INVOICE_TOTAL:24, error : `Line : 2 MATH ERROR`],
                INV-Error_Test2:[[LINE:3, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test2, INVOICE_TOTAL:26, , error : `Line : 3 MATH ERROR | Line : 3 Invoice does not foot Reported`], 
                                [LINE:4, INVOICE_DATE:20150301, INVOICE_NUMBER:INV-Error_Test2, INVOICE_TOTAL:28,]],
                error : [[INV-Error_Test1:`File Error : The file is in an unsupported format`]]

我写了下面的方法来实现上面的

def regex = "^Line\s(?:(\d+)\s)?\s*:\s+(\d+)?.+";
for (e in invLineItems ){
  def errors =  lipErrors.findAll{it.invoiceNumber==e.key} // finding the error messages with the invoice number
  errors.each{  // fetching the line numbre from error message and finding the matching record the invoice number and line number in invLineItems 
     int lineNumber
     if (it.errorMessage.matches(regex)) {
            Pattern p = Pattern.compile("\d+");
            Matcher m = p.matcher(it.errorMessage);
            if (m.find()) {
                 lineNumber = Integer.parseInt(m.group());
            }
          println "lineNumber = "+lineNumber
        }

    if(e.value['LINE_ITEM_NUMBER'].find{it==lineNumber.toString()}) {
      def data = lipErrors.findAll{it.invoiceNumber==e.key && it.errorMessage.matches("^Line\s+"+lineNumber+"?\:\s+"+lineNumber+"?.+")}
      e.getValue().each{it.put("error", data.errorMessage.join("|"))}

     }   

  }
}

代码看起来不像Groovy并且主要使用传统的java代码，我想知道是否可以使用Groovy方法

简化代码

Answer 1

只需要一次迭代。

def invLineItems = [
    '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,]
    ]
]

invLineItems['INV-Error_Test2'].each { 
    println "LINE = "+ it['LINE']
}

invLineItems['INV-Error_Test2'] 给出第二个 Map 条目的值，迭代获取嵌套的 map 条目。

如果您只需要 LINE 的值，那么

assert invLineItems.'INV-Error_Test2'*.'LINE' == [3, 4]

应该够了。
