java.lang.NoSuchMethodError：org.apache.poi.util.IOUtils.copy（Ljava/IO/InputStream的; Ljava/IO/OutputStream中;）V

Question

我有使用Apache POI 3.5

public void UploadXLSX(File file, FileType fileType) 
      { 
     XSSFWorkbook workbook = null; 
     XSSFSheet sheet = null; 
     StringBuilder query = new StringBuilder(); 
     try { 
      workbook = new XSSFWorkbook(new FileInputStream(file)); 
      sheet = workbook.getSheetAt(0); 
      System.out 
        .println("sheet.getLastRowNum() : " + sheet.getLastRowNum() 
          + " First" + sheet.getFirstRowNum()); 
      XSSFRow row; // = sheet.getRow(2); // third row 
      XSSFCell cell;// = row.getCell((short)3); // fourth cell 

程序該應用程序拋出異常

java.lang.NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;)V 

任何意見，如何解決售後服務異常

Answer 1

貌似也有POI的在其中該方法還不存在的類路徑的早期版本。
