내 앱의 "파일 내보내기"옵션을 클릭하면 "다른 이름으로 저장"창이 표시됩니다. ,이 파일은 Apache POI로 작성한 것보다 Excel 2007입니다. 파일은 폴더 "D : \ jboss-6.1.0.Final \ bin"에 올바르게 저장되지만 이상한 기호와 문자을 사용하여 페이지로 리다이렉트하는 "다른 이름으로 저장"창이 표시됩니다.Java에서 Excel 파일을 다운로드 할 때 "다른 이름으로 저장"창이 표시되지 않지만 파일이 올바르게 저장되었습니다.
가장 이상한 것은 내 앱의 다른 페이지에서 Excel의 파일을 다운로드하는 다른 버튼이 있고 POI와 동일한 코드 y와 함께 "다른 이름으로 저장"이 정상적으로 나타납니다.
왜 발생합니까 ???
감사합니다.

함수 수출의 코드는 다음과 같습니다
public void exportarTabla(){
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("Hoja 1");
XSSFRow row;
XSSFCell cell;
for (int i = 0; i < getLstEtiquetasCol().size(); i++) {
row = sheet.createRow(i+3);
for (int j = 0; j < getLstEtiquetasCol().get(i).size(); j++) {
cell = row.createCell(j+3+getLstEtiquetasFil().get(0).size());
cell.setCellValue(getLstEtiquetasCol().get(i).get(j).getValor().getEtiqueta());
}
}
for (int i = 0; i < getLstEtiquetasFil().size(); i++) {
row = sheet.createRow(i+3+getLstEtiquetasCol().size());

이 함수 ExportarTAbla()는 bean의 일부이고 파일은 dndBean.java입니다. 비아에서 무엇을보고 싶니? 내가 원하는 부분을 게시 할 수 있습니다. – Sisi002
