如何在DefaultTableModel传递的Jasper报表表中显示数据

Question

我正在用Java Swing和Jasper Report开发一个项目。

   package pmc;
   import java.util.HashMap;
   import javax.swing.table.DefaultTableModel;
   import net.sf.jasperreports.engine.JRException;
   import net.sf.jasperreports.engine.JasperCompileManager;
   import net.sf.jasperreports.engine.JasperFillManager;
   import net.sf.jasperreports.engine.JasperPrint;
   import net.sf.jasperreports.engine.data.JRTableModelDataSource;
   import net.sf.jasperreports.view.JasperViewer;

   public class SimpleReport1 {

   DefaultTableModel tableModel;

   public SimpleReport1() {
     JasperPrint jasperPrint = null;
      TableModelData();
       try {
            JasperCompileManager.compileReportToFile("src/reports/report1.jrxml");
        jasperPrint = JasperFillManager.fillReport("src/reports/report1.jasper", new HashMap(),
                new JRTableModelDataSource(tableModel));
        JasperViewer jasperViewer = new JasperViewer(jasperPrint);
        jasperViewer.setVisible(true);
    } catch (JRException ex) {
        ex.printStackTrace();

}}

private void TableModelData() {
    String[] columnNames = {"Id", "Name", "Department", "Email"};
    String[][] data = {
        {"111", "G Conger", " Orthopaedic", "[e-mail]"},
        {"222", "A Date", "ENT", "[e-mail]"},
        {"333", "R Linz", "Paedriatics", "[e-mail]"},
        {"444", "V Sethi", "Nephrology", "[e-mail]"},
        {"555", "K Rao", "Orthopaedics", "[e-mail]"},
        {"666", "V Santana", "Nephrology", "[e-mail]"},
        {"777", "J Pollock", "Nephrology", "[e-mail]"},
        {"888", "H David", "Nephrology", "[e-mail]"},
        {"999", "P Patel", "Nephrology", "[e-mail]"},
        {"101", "C Comer", "Nephrology", "[e-mail]"}
    };
    tableModel = new DefaultTableModel(data, columnNames);
}
public static void main(String[] args) {
    new SimpleReport1();
}
}

更改这一行：

JasperCompileManager.compileReportToFile("src/reports/report1.jrxml");

致：

JasperCompileManager.compileReportToFile("src/reports/report1.jrxml","src/reports/report1.jasper");
