public void generateReport() {

        try {

            conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/bsaigsamed?user=root&password=root");

            InputStream input = new FileInputStream(new File("C:/jrxml/idcard.jrxml"));
            JasperDesign jasperDesign = JRXmlLoader.load(input);

            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);

            //Exporting the report
            OutputStream output = new FileOutputStream(new File("D:/Report/Reperesentative_id.pdf"));
            JasperExportManager.exportReportToPdfStream(jasperPrint, output);


            System.out.println("Report Generation Complete");
            conn.close();

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (JRException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();

推荐答案

将其扔到操作系统上，然后让操作系统决定如何打开它.这很容易，免维护并且是常见的方法.

throw it against the OS and let the OS decide on how to open it. That''s easy, maintenance free and the common way.

final Program p = Program.findProgram("pdf");
p.execute(printFilePath);

然后，用户可以决定是否要使用它(例如打印它)或保存它.

The user can then decide if he wants to work with it (e.g. print it) or save it.
