[英]Data fetching issue from excel sheet to selenium web driver using core java
[英]Issue with fetching data from excel (Using Java)
當我兩次調用該函數時,我無法從該函數獲取數據。 該函數返回從Excel工作表獲取的所有行的arrayList。 當我第一次調用該函數時,我得到了正確的行數(除標題行和帶出口的行以外的所有行)。 第二次調用該函數時,我得到0。
似乎文件或第二次創建的工作表發生了某些事情,這是代碼:
private static List<String[]> getDataFromXLS(String excelPath) {
FileInputStream fis;
Workbook workbook; Sheet sheet; XSSFRow row;
Iterator<Row> rows;
XSSFCell cell;
List<String[]> allExcelRows = new ArrayList<String[]>();
String[] xlsRow;
columnNames = new LinkedHashMap<Integer, String>();
paramNames = new LinkedHashMap<String, Integer>();
int totalColumnCount = 0;
int rowNumber = 1;
try {
fis = new FileInputStream(new File(excelPath));
workbook = WorkbookFactory.create(fis);
sheet = workbook.getSheet("TestData");
rows = sheet.rowIterator();
while (rows.hasNext()) {
row = ((XSSFRow) rows.next());
if (rowNumber == 1) {
//based on amount of parameters on first xls row
totalColumnCount = row.getLastCellNum();
}
xlsRow = new String[totalColumnCount];
//check which column is TestType
//iterate through all the columns
for (int columnNumber=0; columnNumber<totalColumnCount; columnNumber++) {
cell = row.getCell(columnNumber, Row.CREATE_NULL_AS_BLANK);
if (getCellValue(cell).trim().toLowerCase().trim().equals("testtype") ){
testTypeColumnIndex = columnNumber; //this is Testtype index
break;
}
}
if (rowNumber != 1) {
for(int columnNumber=0; columnNumber<totalColumnCount; columnNumber++) {
cell = row.getCell(columnNumber, Row.CREATE_NULL_AS_BLANK);
//read only rows before exit
if (columnNumber == testTypeColumnIndex && getCellValue(cell).trim().toLowerCase().trim().equals("exit") ){
reachedExit = true;
break;
}
xlsRow[columnNumber] = getCellValue(cell).trim();
}
//reached exit?
if (reachedExit) {
break;
}
allExcelRows.add(xlsRow);
} else {
//save column names into map
for(int columnNumber=0; columnNumber<totalColumnCount; columnNumber++) {
cell = row.getCell(columnNumber, Row.CREATE_NULL_AS_BLANK);
columnNames.put(columnNumber, getCellValue(cell).trim());
paramNames.put(getCellValue(cell).trim(), columnNumber);
}
}
rowNumber++;
}
} catch (Exception e) {
e.printStackTrace();
}
fis.close();
return allExcelRows;
}
我在這里有點猜測,但是我認為問題在於方法開始時未重置reachedExit
類級別的布爾值。 因此,當您第二次調用它時,此代碼塊將執行:
//reached exit?
if (reachedExit) {
break;
}
....意味着沒有任何東西添加到所有allExcelRows
