Re: [jetty-users] jetty-maven-plugin hot deploy questions

[Bryan Fok <bryanevil@xxxxxxxxxxx>]

HI Jan


Thanks for your reply. I was trying to keep the StatefulResource instance (it has a AutoInteger counter) alive during the redeployment.
Is the hot deployment behavior difference between the jetty-maven-plugin, and normal jetty(embedded or tranditional deployment)?
Is my goal achievable?

Bryan,

When you're running jetty:run  with a non-zero scan time, then when any of the monitored files is changed (eg a class or web.xml etc), the webapp is stopped, configuration re-applied and then then restarted.

Can you describe exactly what is happening that you feel is a problem, providing log traces, exception etc to demonstrate the issue?

regards

Jan

Hi Jetty users and experts

 

I thought that jetty only redeploy the class that got update but it isn't the case. See the below class:

 

@Component

@Path("/")

public class Example1Service {

 

    private final StatefulResource resource;    //referencing to a spring autowired class with an AtomicInteger counter

    private final static Logger logger = LoggerFactory

            .getLogger(Example1Service.class);

 

    @Autowired

    public Example1Service(StatefulResource resource) {

        logger.debug("Example1Service constructed\n");

        this.resource = resource;

    }

 

    @GET

    @Path("counter")

    @Produces(MediaType.TEXT_PLAIN)

    public String getCounter() {

        return "Example1Service(3)" + resource.getCounter(); //change this to Example1Service(1)

    }

}

 

The Example1Service REST class reference to a class auto-wired by Spring autowired. I expecting when i updated the service class, jetty will redeploy this service and auto-wired the same instance again because spring DI by default has a singleton initialization setting, isn't it?

 

Cheers

Bryan
