将 jasper 报告导出为 XLS 格式时不会发生单元格扩展

Question

我有一个带有静态字段和文本的 ireport fields.The 数据库由大部分数据组成，对于数据库中的单行，当我导出 jasper 报告时有多个行 data.So java 代码到 PDF 格式，它正在拉伸、详细说明和打印整个数据，没有任何行丢失，但是当我导出到 XLS 时，它丢失了数据，而且单元格的拉伸不是 happening.I 将显示图像以便更好地理解。

正如您在上面看到的那样，数据以 PDF 格式打印得非常清楚。

在上面，XLS 格式数据被隐藏或在某种意义上 missing.So 我的问题是当报告导出到 XLS 时如何在单元格中显示整个数据 format.I 正在发帖java 下面的代码。

    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();} 

        %>

下面是 jrxml 代码。

Answer 1

首先你在jasper报告中使用了deprecated方法，考虑更新你的代码：

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 中设置 reportElement 的属性，其中包含需要位适合的文本。

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

如果这不能按预期工作，您的解决方案是：

使 excel 更改字体大小（以适合）

configuration.setFontSizeFixEnabled(true)

Flag for decreasing font size so that texts fit into the specified cell height.

在excel

net.sf.jasperreports.export.xls.column.width、属性以像素为单位的整数值

如果您仍然不满意转向apache-poi，请加载工作簿并根据需要进行修改....
