Apache POI, CREATE_NULL_AS_BLANK이 (가) 오류를 일으키는 경우

Question

지금은 데이터 기반 테스트를 Java로 작성하기위한 자습서를 따르고 있습니다. 내 IDE가 인 IntelliJ 커뮤니티 에디션이고, 다음은 내 코드입니다

package utility; 

import config.Constants; 
import executionEngine.DriverScript; 
import org.apache.poi.ss.usermodel.Row; 
import org.apache.poi.xssf.usermodel.XSSFCell; 
import org.apache.poi.xssf.usermodel.XSSFRow; 
import org.apache.poi.xssf.usermodel.XSSFSheet; 
import org.apache.poi.xssf.usermodel.XSSFWorkbook; 

import java.io.FileInputStream; 
import java.io.FileOutputStream; 

public class ExcelUtils { 
    private static XSSFSheet ExcelWSheet; 
    private static XSSFWorkbook ExcelWBook; 
    private static XSSFCell Cell; 
    private static XSSFRow Row; 

    //This method is to set the File path and to open the Excel File 
    //Pass Excel Path and Sheet Name as Arguments to this method 
    public static void setExcelFile(String Path) throws Exception { 
     try { 
      FileInputStream ExcelFile = new FileInputStream(Path); 
      ExcelWBook = new XSSFWorkbook(ExcelFile); 
     }catch(Exception e){ 
      Log.error("Class Utils | Method setExcelFile | Exception desc: " + e.getMessage()); 
      DriverScript.bResult = false; 
     } 
    } 

    @SuppressWarnings("static-access") 
    //This method is used to write value in the excel sheet 
    //This method accepts four arguments (Result, Row Number, Column Number, Sheet Name) 
    public static void setCellData(String Result, int RowNum, int ColNum, String SheetName) throws Exception{ 
     try{ 
      ExcelWSheet = ExcelWBook.getSheet(SheetName); 
      Row = ExcelWSheet.getRow(RowNum); 

      // CHECK IF ERRORS HAPPEN AFTER THIS!!!!!!!!!!!!!!!! 
      Cell = Row.getCell(ColNum, Row.CREATE_NULL_AS_BLANK); 


      if(Cell == null){ 
       Cell = Row.createCell(ColNum); 
       Cell.setCellValue(Result); 
      }else{ 
       Cell.setCellValue(Result); 
      } 
      //Constant variables Test Data path and Test Data file name 
      FileOutputStream fileOut = new FileOutputStream(Constants.Path_TestData); 
      ExcelWBook.write(fileOut); 
      //fielOut.flush(); 
      fileOut.close(); 
      ExcelWBook = new XSSFWorkbook(new FileInputStream(Constants.Path_TestData)); 
     }catch(Exception e){ 
      DriverScript.bResult = false; 
     } 
    } 

    //This method is to read the test data from the Excel cell 
    //In this we are passing Arguments as Row Num, Col Num & Sheet Name 
    public static String getCellData(int RowNum, int ColNum, String SheetName) throws Exception{ 
     try{ 
      ExcelWSheet = ExcelWBook.getSheet(SheetName); 
      Cell = ExcelWSheet.getRow(RowNum).getCell(ColNum); 
      String CellData = Cell.getStringCellValue(); 
      return CellData; 
     }catch(Exception e){ 
      Log.error("Class Utils | Method getCellData | Exception desc: " + e.getMessage()); 
      DriverScript.bResult = false; 
      return ""; 
     } 
    } 

    //This method id to get the row count used of the excel sheet 
    public static int getRowCount(String SheetName){ 
     int iNumber = 0; 
     try { 
      ExcelWSheet = ExcelWBook.getSheet(SheetName); 
      iNumber = ExcelWSheet.getLastRowNum()+1; 
     }catch(Exception e){ 
      Log.error("Class Utils | Method getRowCount | Exception desc: " + e.getMessage()); 
      DriverScript.bResult = false; 
     } 
     return iNumber; 
    } 

    //This method is to get the Row number of the test case 
    //This method takes three arguments(Test Case Name, Column Number & Sheet name) 
    public static int getRowContains(String sTestCaseName, int colNum, String SheetName) throws Exception{ 
     int iRowNum = 0; 
     try{ 
      //ExcelWSheet = ExcelWBook.getSheet(SheetName); 
      int rowCount = ExcelUtils.getRowCount(SheetName); 
      for(; iRowNum<rowCount; iRowNum++){ 
       if(ExcelUtils.getCellData(iRowNum, colNum, SheetName).equalsIgnoreCase(sTestCaseName)){ 
        break; 
       } 
      } 
     }catch(Exception e){ 
      Log.error("Class Utils | Method getRowContains | Exception desc: " + e.getMessage()); 
      DriverScript.bResult = false; 
     } 
     return iRowNum; 
    } 

    //This method is to get the count of the test steps of test case 
    //This method takes three arguments (Sheet name, Test Case ID & Test case row number) 
    public static int getTestStepsCount(String SheetName, String sTestCaseID, int iTestCaseStart) throws Exception{ 
     try{ 
      for(int i=iTestCaseStart; i<=ExcelUtils.getRowCount(SheetName); i++){ 
       if(!sTestCaseID.equals(ExcelUtils.getCellData(i, Constants.Col_TestCaseID, SheetName))){ 
        int number = i; 
        return number; 
       } 
      } 
      ExcelWSheet = ExcelWBook.getSheet(SheetName); 
      int number = ExcelWSheet.getLastRowNum()+1; 
      return number; 
     }catch(Exception e){ 
      Log.error("Class Utils | Method getTestStepsCount | Exception desc: " + e.getMessage()); 
      DriverScript.bResult = false; 
      return 0; 
     } 
    } 
} 

내 문제는 이제 다음 부분입니다 : 내가 지금 무엇을 해야할지하지 않습니다

public static void setCellData(String Result, int RowNum, int ColNum, String SheetName) throws Exception{ 
    try{ 
     ExcelWSheet = ExcelWBook.getSheet(SheetName); 
     Row = ExcelWSheet.getRow(RowNum); 

     // CHECK IF ERRORS HAPPEN AFTER THIS!!!!!!!!!!!!!!!! 
     Cell = Row.getCell(ColNum, Row.CREATE_NULL_AS_BLANK); 

은 ... CREATE_NULL_AS_BLANK 빨간색으로 표시되며, "심볼을 해결할 수 없습니다"라고 말하며 데이터 기반 프레임 워크의 모든 단계가 실패했습니다. 내 로그인이

나는 내 코드를 실행할 수있는이 코드

org.apache.poi.ss.usermodel.Row.MissingCellPolicy.CREATE_NULL_AS_BLANK; 

와 함께 사용하려고하지만 내 프레임 워크는 다음

을 분쇄하기 전에 첫 번째 단계를 수행

누군가가 나를이 문제를 해결하도록 도울 수 있기를 바랍니다.

편집 : "setCellData"부분을 추가하기 전에 프레임 워크가 완전히 작동하고 모든 단계가 완벽하게 실행되었습니다. 그 직후에 오류가 발생합니다

Answer 1

Row.CREATE_NULL_AS_BLANK을 Row.MissingCellPolicy.CREATE_NULL_AS_BLANK으로 바꿉니다.

그리고 (예 : import org.apache.poi.ss.usermodel.Row;) 당신의 "일반" 가져 오기를 사용 나는 v3.17 그것을 업데이트 같은 오류가 발생했습니다, v3.14를 사용하고 있었다

. 이 버전들 사이에 CREATE_NULL_AS_BLANK가 MissingCellPolicy 열거 형 내에 채워 졌으므로 오류가 발생했습니다.
