단일 행을 여러 행으로 변환

Question

반복 행이있는 데이터의 단일 행을 여러 출력 행으로 변환하기 위해 Transformer 단계로 전환하려고합니다.

반복 데이터가 포함 된 여러 열이있는 행이 입력 데이터에 포함되어있는 경우 Transformer 단계를 사용하여 여러 출력 행을 생성하는 방법 (반복되는 각 열마다 하나씩). 입력 :

Col1 Col2 Name1 Name2 Name3 

abc  def  Jim  Bob  Tom 

출력 :

Col1 Col2 Name 

abc  def  Jim 

abc  def  Bob 

abc  def  Tom 

//loop to read data and store in array 

for(i = 0; i <= Lastrow; i++) { 
    for(j = 0; j <= R_endColumn; j++) { 
     Row readrow = sheet.getRow(i); 
     Cell readcell = readrow.getCell(j); 
     String datavalues = df.formatCellValue(readcell); 
     System.out.println(datavalues); 
     localstore[i][j] = datavalues; 
    } 
} 
int newrow_Number = 0; 

for(i = 0; i <= Lastrow; i++) { 
    for(int k = 0; k <= Lengthof_IP; k++) { 
     newrow_Number = newrow_Number + 1; 
     for(j = 0; j <= requirement_endColumn; j++) { 
      Row readrow = sheet.createRow(newrow_Number); 
      Cell readcell = readrow.getCell(j, org.apache.poi.ss.usermodel.Row.CREATE_NULL_AS_BLANK); 
      String datavalues = df.formatCellValue(readcell); 
      readcell.setCellValue(localstore[i][j]); 
     } 
    } 
} 
FileOutputStream out = new FileOutputStream(new File("C:/DataTransformation/op1.xlsx")); 
workbook.write(out); 
out.close();

나는 t를 해결할 수 있었다 그의 코드를 따르면.

 filepath="C:/DataTransformation/Book1_New1.xlsx"; 
      File file = new File(filepath); 

      filepath = file.getPath(); 

      //File file = new File("C:/Input/Programfiles/TestStepTable.xlsx"); 
       System.out.println(filepath); 
       XSSFWorkbook workbook = new XSSFWorkbook(filepath); 
       XSSFSheet sheet = workbook.getSheetAt(0); 



       DataFormatter df = new DataFormatter(); 
       int Lastrow= sheet.getLastRowNum(); 
       int k = requirement_endColumn; 
       System.out.println("Column for requirement: " + k); 
       ArrayList myList = (ArrayList) new ArrayList(); 
       ArrayList myList1 = (ArrayList) new ArrayList(); 

       int lengthofInput= input_endColumn-input_startColumn; 
       int lengthofOutput= output_endColumn-output_startColumn; 
       int Lengthofloop; 

       if(lengthofInput>=lengthofOutput) 
       { 
        Lengthofloop=lengthofInput; 
       } 
       else 
       { 
        Lengthofloop=lengthofOutput; 
       } 
       int i; 
       int j; 
       String[][] localstore= new String[100][100]; 
       //java.util.Iterator<Row> rowIterator = sheet.iterator(); 

       for (i = 0; i <=Lastrow; i++) // Change this max value of i upto total row number in the file
