jasperreport报表的简易demo

//这里只要是为输出的excel文件设置各种高属性，文件名 sheetname 。。。public void exportFile(HttpServletResponse res , JasperPrint print , String outputFileName,OutputStream outputStream) throws JRException{JRAbstractExporter jrExporter = new JRXlsxExporter();jrExporter.setParameter(JRExporterParameter.JASPER_PRINT, print);    jrExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);    jrExporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);    jrExporter.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN, Boolean.TRUE);    jrExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);    jrExporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);    jrExporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);    if(outputFileName!=null && !outputFileName.isEmpty()){    jrExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outputFileName);    }    System.out.println("exportFile:outputFileName outputStream " + outputFileName + " " + outputStream);    jrExporter.setParameter(JRXlsExporterParameter.SHEET_NAMES, new String[]{"信息"});     jrExporter.exportReport();}
