所以现在我将它作为一个精度为 1000 的长字符串读取，然后我想使用 Java 转换并将它们与分布在多个标题中的列名拆分，并将它们与下面的值相关联。一个输入行将登陆尽可能多的目标行。

第一件事：将文件逐行读入一个长字符串端口。

将“CurrentlyProcessedFileName”端口添加到源以捕获文件名。
计算读取的行数

用逗号分隔行 - 我该如何实现？猜测表达式或java转换以及java中的以下整个过程或者我可以使用SP，但是我如何用逗号分割行？

   If Current RowNumber = 1 Then    
        vINVC_BGN_DT := field1
        vINVC_END_DT := field2

   If Current RowNumber > 1
      If field1 != $$CARRIER Then
    NAME1 := NAME1 || field1  #Initialize NAME variables to an empty string
    NAME2 := NAME2 || field2
    NAME3 := NAME3 || field3  #repeat for each comma seperated field
      If field1 = $$CARRIER Then
    VALUE1 := field1
    VALUE2 := field2
    VALUE3 := field3          #repeat for each comma seperated field

对于每个源行，输出行数应等于不同 Amount_types 的计数，（不包括空行）

   For i in NAME4.NAMEx loop
       if NAMEi is not spaces or null then generate row
           target.INVC_TYPE = "CLAIM"
           target.FILE_RECEIPT_SK
           target.CARRIER := VALUE1
           target.CNTRCT := VALUE2
           target.PBM_GROUP := VALUE3
           target.INVC_BGN_DT := vINVC_BGN_DT  #From row1
           target.INVC_END_DT := vINVC_END_DT  #From row1
           target.INVC_AMOUNT_TYPE := NAMEi
           target.INVC_AMOUNT := VALUEi
   end i loop..

您可以使用规范器将一行拆分为多行。在您的情况下，您必须分别处理第一行、接下来的 3 个标题行和数据行。为此，使用变量在表达式中创建一个序列号。

您可以在表达式本身中获取开始日期和结束日期：例如。

begin_date:= iif(seq=1, field1, begin_date)

要分隔标题行和数据行，请使用带有条件的 rouerseq>1 && seq<=4和seq>4

现在您可以使用规范器将行拆分为多行。对于数据行，为运营商、合同、pbm_group、计数和金额创建 5 列，并将计数和金额的出现设置为总数。或计数或金额列。

您可以类似地对标题列使用另一个规范化器。最后使用连接器转换连接两个流。

您还可以使用 java 转换，在输入行选项卡中，您已经编写了类似的逻辑。要拆分行，您可以使用 split 方法。前任：

String[] fields=row.split(",");

现在数组fields将包含所有字段作为数组元素。您可以将适当的元素分配给输出端口并调用 Informatica 的generateRow()方法来创建目标记录。
