現在我正在編寫一個用Java編寫數據驅動測試的教程。我的IDE是的IntelliJ社區版和下面是我的代碼Apache POI，CREATE_NULL_AS_BLANK導致錯誤
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;
}
}
}
我現在的問題是以下部分：
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);
我不知道現在該做什麼...... CREATE_NULL_AS_BLANK被標記爲紅色，說「無法解析符號」，我的數據驅動框架的每一步都失敗了。
我試圖用
org.apache.poi.ss.usermodel.Row.MissingCellPolicy.CREATE_NULL_AS_BLANK;
使用它有了這個代碼，我可以執行我的代碼，但我的框架不只是第一步破碎
這裏之前是我的日誌

我希望有人能幫我解決這個問題，因爲這會讓我瘋狂。
編輯：在我添加「setCellData」部分之前，框架完全正常工作，每一步都完美無瑕地執行。在此之後發生的錯誤
您使用的是什麼版本的Apache POI？如果不是最新的，升級時會發生什麼？ – Gagravarr
我用3.17 ...那是錯誤發生的地方...然後我也試着降級到3.10.1，但是錯誤仍然存在 – Pawana
