我試圖以excel(xls)格式導出報告,並在打開/保存對話框幫助下從瀏覽器中下載文件。JasperReports:將報告導出到Excel時文件名不正確
當文件下載框彈出時,文件名不能正確顯示。該文件名來作爲URL
下面是我的代碼:
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReportMCQ, params, datasource);
JRXlsExporter jasperXlsExportMgr = new JRXlsExporter();
ByteArrayOutputStream xlsReport = new ByteArrayOutputStream();
jasperXlsExportMgr.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.TRUE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, java.lang.Boolean.FALSE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, java.lang.Boolean.FALSE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, java.lang.Boolean.TRUE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS, java.lang.Boolean.TRUE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN, java.lang.Boolean.TRUE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.IS_IGNORE_CELL_BORDER, java.lang.Boolean.FALSE);
jasperXlsExportMgr.setParameter(JRXlsExporterParameter.CREATE_CUSTOM_PALETTE, java.lang.Boolean.TRUE);
jasperXlsExportMgr.setParameter(JRExporterParameter.OUTPUT_STREAM, xlsReport);
jasperXlsExportMgr.exportReport();
bytes = xlsReport.toByteArray();
getResponse().setHeader("Content-disposition", "attachment; filename=\"report.xls\"");
getResponse().setContentType("application/vnd.ms-excel");
getResponse().setContentLength(bytes.length);
if (bytes.length > 0) {
servletOutputStream.write(bytes, 0, bytes.length);
servletOutputStream.flush();
servletOutputStream.close();
}
