解析xml

Question

我试图在解析xml后显示带有复选框的表。但是，当我尝试编辑复选框时，它引发了一个异常，表示无法将String强制转换为boolean。

public class CheckGlobalOptionsPanel{
    private JPanel rootPane;
    private ConvertXmlToObjects convertXmlToObjects;

    @Override
    public JComponent getComponent() {
        if (rootPane == null) {
            rootPane = new JPanel(new BorderLayout());
            rootPane.add(createXMLRulePanel(), BorderLayout.CENTER);
        }

        return rootPane;
    }

    private JPanel createXMLRulePanel() {
        JTable jTable = new JTable();
        JScrollPane sp = null;
        try {
            convertXmlToObjects = new ConvertXmlToObjects();
            RulesetType rulesetType = convertXmlToObjects.convertToObjects(null);

            DefaultTableModel model = new DefaultTableModel();
            jTable.setModel(model);
            model.addColumn("Sl. No.");
            model.addColumn("Rule Name");
            model.addColumn("Message");
            model.addColumn("Priority");
            model.addColumn("Active");
            for (int i = 0; i < rulesetType.getRule().size(); i++) {
                model.addRow(new Object[]{i, rulesetType.getRule().get(i).getRef(), rulesetType.getRule().get(i).getMessage(),
                        rulesetType.getRule().get(i).getPriority(), true});
            }
            sp = new JScrollPane(jTable);
            jTable.setVisible(true);
            jTable.setDefaultRenderer(Object.class, new XMLCellRenderer());

        } catch (JAXBException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        JPanel xmlPanel = new JPanel(new VerticalFlowLayout());
        xmlPanel.setBorder(BorderFactory.createEmptyBorder(0, 0, 4, 0));
        xmlPanel.add(sp);

        return xmlPanel;
    }

    private class XMLCellRenderer implements TableCellRenderer {
        DefaultTableCellRenderer DEFAULT_RENDERER = new DefaultTableCellRenderer();
        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            Component objComponent = DEFAULT_RENDERER.getTableCellRendererComponent(table,
                    value, isSelected, hasFocus, row, column);
            JCheckBox jCheckBox = new JCheckBox();
            if (column == 4) {
                if (value != null) {
                    jCheckBox.setSelected((Boolean) value);
                }
                return jCheckBox;
            }
            return objComponent;
        }
    }
}

由于最后一列被定义为布尔值，因此我在对象数据的最后传递了一个布尔值。

一旦我开始编辑复选框，它将显示为“ true”的文本。任何建议将不胜感激。
