将 Hibernate 连接与 JasperReports 结合使用

Question

I'm making now a new module into a big one web application. I've created in iReport a report with Hibernate Connection. All Hibernate classes were already made by my teammates, hql query also. So, we can say, I've made only "visual" part in designer.

In iReport all works great, like I wanted. I'm using hibernate.cfg.xml file where session factory is defined.

My problem began when I wanted to integrate my *.jrxml file with java web app. Web application is made on maven using Spring Framework. So I have additional file applicationContext.xml where hibernate session factory is also defined like in hibernate.cfg.xml.

The question is, is it possible to make it's working, using @autowired on bean from applicationContext.xml?

@Autowired
@Qualifier("binderSessionFactory")
protected SessionFactory sessionFactory;

If yes, how could I give this connection so it work's with my *.jrxml file?

Java code:

OutputStream outputStream = response.getOutputStream();

Map parameters = (Map) model.get("parameters");

URL reportTemplate = getClass().getClassLoader().getResource("pathToFile/file.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(reportTemplate.getPath());
jasperPrint = JasperFillManager.fillReport(jasperReport, parameters);

JasperExportManager.exportReportToPdfStream(jasperPrint, outputStream);

How should I make a hibernate db connection visible for my report?

To answer you first question, yes it is possible. Please refer to this links for the required configuration needed for the JasperReports-Hibernate integration: JasperReports 5.6.0 - Hibernate Sample and
Using Hibernate queries in JasperReports
While this last link is shows the specific requirement for Spring: JasperReports - Spring MVC
Hope these helps.
