【Stimulsoft Reports Java教程】运行时创建报表

下载Stimulsoft Reports Java最新版本

此示例项目显示了在运行时创建报表并在查看器中显示报表的可能性。您只需要显示报表的本机Java查看器，以及使用组件创建报表的几行代码。

首先，我们需要创建Java查看器。创建JFrame，设置必要的选项并添加查看器控件。

public class CreateReport extends JPanel {
 
    private static final long serialVersionUID = 330448692680237867L;
    private static final Dimension FRAME_SIZE = new Dimension(800, 800);
 
    public static void main(final String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                try {
                    JFrame frame = new JFrame();
                    frame.add(new CreateReport(frame));
                    frame.setSize(FRAME_SIZE);
                    frame.setLocationRelativeTo(null);
                    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                    frame.setVisible(true);
                } catch (Throwable e) {
                    StiExceptionProvider.show(e, null);
                }
            }
        });
    }
    public CreateReport(final JFrame parentFrame) throws FileNotFoundException {
    setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
    setPreferredSize(FRAME_SIZE);
    StiViewerFx viewerPanel = new StiViewerFx(parentFrame);
    add(viewerPanel);
...

接下来，创建新的报表对象，然后使用Demo XML和XSD文件的路径创建XML数据集对象，并将其添加到报表中。

...
    StiReport report = new StiReport();
 
    StiPage page = new StiPage(report);
    report.getPages().add(page);
    page.setName(StiNameCreation.createName(report, StiNameCreation.generateName(page)));
    String xsdPath = "/samples/Demo.xsd";
    StiXmlDatabase xmlDatabase = new StiXmlDatabase("Demo",
        StiResourceUtil.getStream(xsdPath), StiResourceUtil.getStream("/samples/Demo.xml"));
    report.setDictionary(new StiDictionary(report));
    report.getDictionary().getDatabases().add(xmlDatabase);
...

接下来，从Demo数据库中提取信息，并使用Categories名称创建TableSource 。

...
    StiXmlTableFieldsRequest tables = StiDataColumnsUtil.parceXSDSchema(StiResourceUtil.getStream(xsdPath));
    StiDataTableSource tableSource = null;
    for (StiXmlTable table : tables.getTables()) {
        if (table.getName().equals("Categories")) {
            tableSource = new StiDataTableSource("Demo." + table.getName(), table.getName(), table.getName());
            tableSource.setColumns(new StiDataColumnsCollection());
            for (StiSqlField field : table.getColumns()) {
                StiDataColumn column = new StiDataColumn(field.getName(), field.getName(), field.getSystemType());
                tableSource.getColumns().add(column);
            }
            tableSource.setDictionary(report.getDictionary());
            report.getDictionary().getDataSources().add(tableSource);
        }
    }
...

现在我们需要创建报表组件。首先，使用Text组件将Header band添加到报告页面。这些组件将显示报表标题。

...
    // Create TitleBand
    StiHeaderBand titleBand = new StiHeaderBand();
    titleBand.setHeight(0.85);
    titleBand.setName("TitleBand");
    page.getComponents().add(titleBand);
 
    // Create Title text on header
    StiText headerText = new StiText(new StiRectangle(0, 0, page.getWidth(), 0.85));
    headerText.setTextInternal("Tacticdescription");
    headerText.setHorAlignment(StiTextHorAlignment.Left);
    headerText.setName("TitleHeader");
    headerText.setFont(new StiFont("Arial", 12F, StiFontStyle.Bold));
    titleBand.getComponents().add(headerText);
 
    // Create HeaderBand
    StiHeaderBand headerBand = new StiHeaderBand();
    headerBand.setHeight(0.5);
    headerBand.setName("HeaderBand");
    page.getComponents().add(headerBand);
...

接下来，使用“Text”字段和“Image”字段添加“Data”区域。这些组件将显示报表数据。

...
    double pos = 0;
    double columnWidth = page.getWidth() / tableSource.getColumns().size();
    Integer nameIndex = 1;
    for (StiDataColumn dataColumn : tableSource.getColumns()) {
        // Create text on header
        StiText hText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
 
        hText.setTextInternal(dataColumn.getName());
        hText.setHorAlignment(StiTextHorAlignment.Center);
        hText.setName("HeaderText" + nameIndex.toString());
        hText.setBrush(new StiSolidBrush(StiColorEnum.Orange.color()));
        hText.getBorder().setSide(StiBorderSides.All);
        headerBand.getComponents().add(hText);
 
        if (dataColumn.getName().equals("Picture")) {
            StiImage dataImage = new StiImage(new StiRectangle(pos, 0, columnWidth, 0.5));
            dataImage.setDataColumn("Categories." + dataColumn.getName());
            dataImage.setName("DataImage" + nameIndex.toString());
            dataImage.getBorder().setSide(StiBorderSides.All);
            dataBand.getComponents().add(dataImage);
        } else {
            StiText dataText = new StiText(new StiRectangle(pos, 0, columnWidth, 0.5));
            dataText.setText("{Categories." + dataColumn.getName() + "}");
            dataText.setName("DataText" + nameIndex.toString());
            dataText.getBorder().setSide(StiBorderSides.All);
            dataBand.getComponents().add(dataText);
        }
        pos = pos + columnWidth;
        nameIndex++;
    }
...

最后，渲染报表并在查看器中显示它。

...
    report.Render();
 
    viewerPanel.getStiViewModel().getEventDispatcher().dispatchStiEvent(
        new StiViewCommonEvent(StiViewCommonEvent.DOCUMENT_FILE_LOADED, new StiDocument(report), null));
}

在下面的屏幕截图中，您可以看到示例代码的结果。
