下載Stimulsoft Reports Java最新版本

此示例項目顯示了在運行時創(chuàng)建報表并在查看器中顯示報表的可能性。您只需要顯示報表的本機Java查看器，以及使用組件創(chuàng)建報表的幾行代碼。

首先，我們需要創(chuàng)建Java查看器。創(chuàng)建JFrame，設置必要的選項并添加查看器控件。

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);
...

接下來，創(chuàng)建新的報表對象，然后使用Demo XML和XSD文件的路徑創(chuàng)建XML數(shù)據(jù)集對象，并將其添加到報表中。

...
    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);
...

接下來，從Demo數(shù)據(jù)庫中提取信息，并使用Categories名稱創(chuàng)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);
        }
    }
...

現(xiàn)在我們需要創(chuàng)建報表組件。首先，使用Text組件將Header band添加到報告頁面。這些組件將顯示報表標題。

...
    // 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);
...

接下來，使用“Text”字段和“Image”字段添加“Data”區(qū)域。這些組件將顯示報表數(shù)據(jù)。

...
    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，渲染報表并在查看器中顯示它。

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