Starting and Stopping a service instance in Spring MVC

Question

I am planning to use JODConverter to do my conversion of office files to PDF. From the tutorial I read that the API instance should be started when the web app starts and closed when the web app closes.

The code would be something like

// web app starts
OfficeManager officeManager = new ManagedProcessOfficeManager();
officeManager.start();

OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
converter.convert(sourceFile,targetFile);

// web app stops
officeManager.stop();

The question is where do put the lines of code for starting and stopping the instance (XML or Java classes) ?

I've configured my service to implements `org.springframework.context.Lifecycle`. Thanks! — abiieez, Oct 14 '14 at 06:20
As the doc says, the best, modern, recommended way is ti use PreDestroy and PostConstruct annotated methods. — JB Nizet, Oct 14 '14 at 06:21

Based on the information provided by JB Nizet, I got it working with

@Service
public class JODConverter {

    OfficeManager officeManager;

    public void convertToPDF() {
        OfficeDocumentConverter converter = new OfficeDocumentConverter(
                officeManager);
        converter.convert(new File("test.odt"), new File("test.pdf"));
    }

    @PostConstruct
    public void start() {
        officeManager = new DefaultOfficeManagerConfiguration()
                .buildOfficeManager();
        officeManager.start();
    }

    @PreDestroy
    public void stop() {
        officeManager.stop();
    }

}
