Jersey contextConfig support

[Jotschi]

It would be great if it would be possible to add support for the contextConfig resource config setting. In my case the setting is a spring AnnotationConfigApplicationContext object. The object can't be passed on to the DefaultJerseyOptions via the vert.x config mechanism. Do you have an idea how to handle this setting? I added a static setter to the DefaultJerseyOptions class in order to test it.

Do you have a snippet you can post? I don't follow what you mean by:
add support for the contextConfig resource config setting

Do you need a way to control creation of the ResourceConfig? You can extend DefaultJerseyOptions and override getResourceConfig() and do whatever you need. Does that help?

Yes that helps. How can i unbind the DefaultJerseyOptions? The HK2JerseyBinder is binding and my own binder is used once the DefaultJerseyOptions has already been used.

public class JerseyOptionsWithContextInfo extends DefaultJerseyOptions {

    public static Object context;

    @Inject
    public JerseyOptionsWithContextInfo(@Optional ServiceLocator locator) {
        super(locator);
    }

    @Override
    protected ResourceConfig getResourceConfig() {
        ResourceConfig rc = super.getResourceConfig();
        if (context != null) {
            rc.property("contextConfig", context);
        }
        return rc;
    }

}

/**
 * HK2 Jersey binder
 */
public class AppBinder extends AbstractBinder {

    @Override
    protected void configure() {
        bind(JerseyOptionsWithContextInfo.class).to(JerseyOptions.class);
    }

}

My idea was to replace DefaultJerseyOptions with the JerseyOptionsWithContextInfo class but i just noticed that the DefaultJerseyOptions are responsible for handling the binders option. Do you have a suggestion on how to deal with this usecase?

[Jotschi]

Got it!

I'm now extending the HK2JerseyBinder and using the _hk2_binder_ config instead of _binders_.

/**
 * HK2 Jersey binder
 */
public class AppBinder extends HK2JerseyBinder {

    @Override
    protected void configure() {
        bind(JerseyOptionsWithContextInfo.class).to(JerseyOptions.class);
        super.configure();
    }

}

Yes, that is what I was thinking.

Two things to consider:

1. You can, but don't need to extend HK2JerseyBinder. Alternatively you can specify multiple binders as a json array in config or you can call install(new HK2JerseyBinder()); from your binder. All three approaches should work fine.
2. You should probably set the rank to ensure your implementation of JerseyOptions is chosen: bind(JerseyOptionsWithContextInfo.class).to(JerseyOptions.class).ranked(10);
