這裏是我的代碼我有3個textfields和1個comboBox.I hava使用mysql數據庫和休眠我可以創建一個碧玉報告（/home/webwerks/gitpro/Swing/src/report5.jrxml「）給這樣的路徑沒關係，但我已經設置了outfile（jasper report）的動態路徑，你可以看到jButton5ActionPerformed代碼，我可以給這樣的outfile的靜態路徑（JasperExportManager.exportReportToPdfFile（jasperPrint，「/ home/webwerks/report在這個地方我可以給動態路徑.PDF「）如何請幫我Swing應用程序桌面

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {           

    if (evt.getSource() == jButton1) { 
      String s = jTextField1.getText(); 
      String s1 = jTextField2.getText(); 
      String s2 = jTextField3.getText(); 
      String s4 = (String) jComboBox1.getSelectedItem(); 
      Session session = HibernateUtil.getSessionFactory().openSession(); 
      session.beginTransaction(); 
      Performance performance = new Performance(); 
      performance.setFirerating(s4); 
      performance.setSoundrating(s); 
      performance.setWidth(s1); 
      performance.setMaxheight(s2); 
      session.save(performance); 
      session.flush(); 
     } 
    }           

    private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {           
     // TODO add your handling code here: 
     if (evt.getSource() == jButton5) { 
      try { 
       Session session = HibernateUtil.getSessionFactory().openSession(); 
       List l = ((org.hibernate.classic.Session) session).find("from Hibernate.Performance"); 
       Map parameters = new HashMap(); 
       InputStream input = new FileInputStream("/home/webwerks/gitpro/Swing/src/report5.jrxml"); 
       JasperDesign jasperDesign = JRXmlLoader.load(input); 
       JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign); 
       JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(l); 
       JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, ds); 
       JasperExportManager.exportReportToPdfFile(jasperPrint, "/home/webwerks/report.pdf"); 
      } catch (Exception e) { 
      } 
     } 
    }

您需要使用JFileChooser的，就像在this tutorial

所示

final JFileChooser fc = new JFileChooser(); 
// configure file chooser if needed 
int returnVal = fc.showSaveDialog(jButton5); 
if (returnVal == JFileChooser.APPROVE_OPTION) { 
    String filename = fc.getSelectedFile().getAbsolutePath(); 
    // Put your code here to generate the report. 
}
