如何使用 criteria.uniqueResult(); 填充碧玉報告？

Question

我想使用customerId查看報告。

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, ?, ?);// How to fill?

我試過了：
BLManager.java

public void report(int custId) throws JRException, FileNotFoundException {
        Session session = sessionFactory.openSession();
        Criteria criteria = session.createCriteria(Customer.class);
        criteria.add(Restrictions.eq("custId", custId));
        Customre customer = (Customer) criteria.uniqueResult();

        FileInputStream fis = new FileInputStream("src/com/customer/reports/report.jrxml");
        BufferedInputStream bis = new BufferedInputStream(fis);

        JasperReport jasperReport = (JasperReport) JasperCompileManager.compileReport(bis);
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, ?, ?);// How to fill?

        JasperViewer.viewReport(jasperPrint, false);
    }

此外，我在buttonClick上調用此方法
Client Class

@FXML
private void viewReport(ActionEvent e) {
    Customer customer = customerTable.getSelectionModel().getSelectedItem();
    if (customer != null) {
        int custId = customer.getCustId();
        try {
            bLManager.report(custId);
        } catch (FileNotFoundException | JRException ex) {
            Logger.getLogger(FollowUpController.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

當您使用JasperFillManager的fillReport方法時，您可以傳遞一個parameterMap 。

parameterMap映射是HashMap ，您將報告管理的參數名稱作為鍵，並將 object 實例作為值。

這是我填充parameterMap的代碼（您可以將其用作您的案例的示例）：

Map<String, Object> parameterMap = new HashMap<String, Object>;
parameterMap.put("datasource", jRdataSource);
parameterMap.put("MyComplexObject", myComplexObject); // you can pass a pojo
parameterMap.put("Title", "My report title");
