如何使用 criteria.uniqueResult(); 填充碧玉报告？

Question

I want to view report by using customerId .

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

I tried:
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);
    }

Further I calling this method on buttonClick
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);
        }
    }
}

When you use fillReport method of JasperFillManager , you can pass a parameterMap .

A parameterMap is a HashMap where you put as key the name of paramter managed by the report, and as value the object instance.

This is my code to fill parameterMap (you can use as example for your case):

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");

You can see the documentation about JasperFillManager methods here
