导入excel文件POI解析 时报错：
FileInputStream file = new FileInputStream(new File("G:\\TestData\\test.xls")); //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();
报错：
org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13] at org.apache.poi.util.PackageHelper.open(PackageHelper.java:41) at org.apache.poi.xssf.usermodel.XSSFWorkbook.<init>(XSSFWorkbook.java:218)
解决:
//Create Workbook instance holding reference to .xlsx file XSSFWorkbook workbook = new XSSFWorkbook(file);
修改为：
import org.apache.poi.ss.usermodel.Workbook; Workbook workbook = WorkbookFactory.create(file);
