问题
I've followed a simple guide to constructing a workbook using Apache POI XSSF. Following the same guide I was able to WRITE an Excel sheet, however when attempting to read from one, I'm receiving the error displayed after the code.
Code:
try {
FileInputStream file = new FileInputStream(new File("howtodoinjava_demo.xlsx"));
// Create Workbook instance holding reference to .xlsx file
XSSFWorkbook workbook = new XSSFWorkbook(file);
// Get first/desired sheet from the workbook
XSSFSheet sheet = workbook.getSheetAt(0);
// Iterate through each rows one by one
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
// For each row, iterate through all the columns
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
// Check the cell type and format accordingly
switch (cell.getCellType()) {
case Cell.CELL_TYPE_NUMERIC:
System.out.print(cell.getNumericCellValue() + "t");
break;
case Cell.CELL_TYPE_STRING:
System.out.print(cell.getStringCellValue() + "t");
break;
}
}
System.out.println("");
}
file.close();
} catch (Exception e) {
e.printStackTrace();
}
Error output:
Exception in thread "main" java.lang.NoSuchFieldError: RAW_XML_FILE_HEADER at org.apache.poi.openxml4j.opc.internal.ZipHelper.verifyZipHeader(ZipHelper.java:179) at org.apache.poi.openxml4j.opc.internal.ZipHelper.openZipStream(ZipHelper.java:228) at org.apache.poi.openxml4j.opc.ZipPackage.(ZipPackage.java:93) at org.apache.poi.openxml4j.opc.OPCPackage.open(OPCPackage.java:294) at org.apache.poi.util.PackageHelper.open(PackageHelper.java:37) at org.apache.poi.xssf.usermodel.XSSFWorkbook.(XSSFWorkbook.java:273) at com.wtolliver.spring.test.ReadExcel.readExcel(ReadExcel.java:18) at com.wtolliver.spring.test.App.main(App.java:17)
回答1:
After looking around a bit. I browsed the documentation for APACHE POI, and saw that this was one of the constants(not that i know what that really means). But eventually, I realized all the tutorials I used were pre-2014, so I just changed my Maven POM to version 3.11 of apache POI, and POI-OOXML. Its working now.

I got same error with different constant.
Exception in thread "main" java.lang.NoSuchFieldError: RETURN_NULL_AND_BLANK poi.
Googled lot but no answer. I was using apache poi-ooxml-3.11, later I changed to 3.17 then it was working fine.
Hope this might helpful someone.

I got the same error, try changing the XSSFWorkbook diclaration to HSSFWorkbook. It worked for me.
回答4:

Please perform following task: upgrade the APACHE POI 3.** to the latest version in my case i have done the following thing i was previously using the apache poi 3.09 later i have upgraded the lib to latest version i.e 3.12 and its work !!
Perform the following steps and your code will but make sure the error should be same.
