將jasper報告導出爲XLS格式時沒有發生單元格擴展

我有一個帶有靜態字段和文本字段的ireport。數據庫由大部分數據組成，對於數據庫中的單個行有多行數據。因此，當我我正在通過java代碼將jasper報告導出爲PDF格式，它正在擴展和詳細描述和打印整個數據，而不會丟失任何行，但是當我輸出到XLS時，它缺少數據，而且單元格的伸展不會發生。顯示圖像以便更好地理解。將jasper報告導出爲XLS格式時沒有發生單元格擴展

正如你可以在上面看到的數據打印非常清晰的PDF格式。

在上面，這是XLS格式數據隱藏或在感覺missing.So我的問題是如何顯示報告導出到XLS格式的單元格中的整個數據。我在下面張貼Java代碼。

ServletContext context = request.getServletContext(); 
    String fullPath = context.getRealPath("/WEB-INF/reports/report5.jrxml"); 
    InputStream input = new FileInputStream(new File(fullPath)); 
    JasperDesign jasperDesign = JRXmlLoader.load(input); 

    System.out.println("Compiling Report Designs"); 
    JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign); 

    System.out.println("Creating JasperPrint Object"); 
    HashMap<String,Object> map = new HashMap<String,Object>(); 
    map.put("sql",sql); 
    JasperPrint jasperPrint = JasperFillManager.fillReport (jasperReport,map,conn); 
    byte bytes[] = new byte[10000]; 
    //String result = JasperRunManager.runReportToHtmlFile("./usertemplates/test.jasper" , parameters, conn); 



    JRXlsxExporter exporter = new JRXlsxExporter(); 
    ByteArrayOutputStream xlsReport = new ByteArrayOutputStream(); 
exporter.setExporterInput(new SimpleExporterInput(jasperPrint)); 
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(xlsReport)); 
SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration(); 
configuration.setWhitePageBackground(true); 
configuration.setDetectCellType(true); 
configuration.setFontSizeFixEnabled(true); 
exporter.setConfiguration(configuration); 
exporter.exportReport(); 
    //System.out.println("Size of byte array:"+xlsReport.size()); 
    //bytes = xlsReport.toByteArray(); 
    String fileName = "InvoiceReport.xls"; 
response.setHeader("Content-Disposition", "inline; filename=" 
+ fileName); 
    response.setContentType("application/vnd.ms-excel"); 
    //System.out.println("After JasperPrint = 1"); 
    response.setContentLength(xlsReport.size()); 
    //System.out.println("After JasperPrint = 2"); 
    //xlsReport.close(); 
    //System.out.println("After JasperPrint = 3"); 

    OutputStream outputStream = response.getOutputStream(); 
    System.out.println("After JasperPrint = 4"); 
    xlsReport.writeTo(outputStream); 
    outputStream.flush(); 
    //outputStream.close(); 
    } 
    catch(Exception e) 
    {e.printStackTrace();} 

     %>

和jrxml代碼如下。

report5.jrxml

我把這兩個在但它不工作。 –

首先你正在使用碧玉報告deprecated方法，考慮更新代碼：

JRXlsxExporter exporter = new JRXlsxExporter(); 
exporter.setExporterInput(new SimpleExporterInput(jasperPrint)); 
xporter.setExporterOutput(new SimpleOutputStreamExporterOutput(xlsReport)); 
SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration(); 
configuration.setWhitePageBackground(true); 
configuration.setDetectCellType(true); 
\\... set all your configuration like above 
exporter.setConfiguration(configuration); 
exporter.exportReport();

您需要在textField在reportElement的設置屬性包含需要適合的文本。

<property name="net.sf.jasperreports.export.xls.auto.fit.row" value="true"/> 
<property name="net.sf.jasperreports.export.xls.auto.fit.column" value="true"/>

如果這是不工作的期望您的解決方案是：

使Excel改變字體大小（以適應）

configuration.setFontSizeFixEnabled(true)

標誌用於減少字體大小，以便文本符合指定的單元格高度。

手動設置列的寬度在Excel

net.sf.jasperreports.export.xls.column.width，與以像素爲單位

如果一個整數值屬性您仍不滿意轉apache-poi ，加載工作簿並修改它，只要你喜歡....

我已經完成了你所說的，但它仍然是一樣的。不擴展cell.You可以看到上面的代碼被編輯 –

在excel中發生了什麼？任何更改？ –

否。在PDF格式中，它正在擴展，如上所示，並且以XLS格式顯示一些正在打印並且一些正在隱藏 –
