Question

我正在使用Apache Poi将数据复制到excel工作表中。我想像同一张纸一样从D列复制到G列。但是，当我尝试从D列复制到G列时，出现异常-

INFO [http-nio-9080-exec-8] org.apache.cxf.phase.PhaseInterceptorChain.doDefaultLogging应用程序{http://service.ccc.com/} excelS引发了异常，现在展开：org.apache.poi.openxml4j。 exceptions.OpenXML4JRuntimeException：规则M2.4异常：永远不会发生此错误，如果是这样，请向开发团队发送邮件，谢谢！警告[http-nio-9080-exec-8] org.apache.cxf.phase.PhaseInterceptorChain.unwind拦截器org.apache.cxf.jaxrs.interceptor.JAXRSDefaultFaultOutInterceptor@33b5e6de上的handleFault异常 org.apache.cxf.interceptor.Fault：规则M2.4异常：永远不会发生此错误，如果是这样，请向开发团队发送邮件，谢谢！

请告诉我问题出在哪里以及如何解决。.

public class excelS {


   public void copyColumn(String fileId, int sourceCol, int targetColumn) {
        Long l = Long.valueOf(fileId);
        excelDetail x = (excelDetail) componentList.get(l);
        Sheet sheet = x.wb.getSheetAt(x.wb.getSheetIndex(x.sheetName));

        for (int rId = 0; rId <= sheet.getLastRowNum(); rId++) {
            Row row = sheet.getRow(rId);
            if (row != null) {
                Cell oldCell = row.getCell(sourceCol);
                if (oldCell != null) {
                    Cell newCell = row.createCell(targetColumn, oldCell.getCellType());
                    cloneCellWithStyle(newCell, oldCell);
                } else {
                    row.createCell(targetColumn, Cell.CELL_TYPE_BLANK);
                }
            }
        }

        try {
            FileOutputStream fos = new FileOutputStream(x.path);
            x.wb.setForceFormulaRecalculation(true);
            x.wb.write(fos);
            fos.close();
            rm.setResult("success");
            rm.setValue("column has been copied.");
        } catch (IOException e) {
            e.printStackTrace();
            rm.setResult("error");
            rm.setValue(e.getMessage());
        }
    }
}

为什么会出现org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException：规则M2.4异常？
