Dropwizard guice integration

@oeddyo

I meant that: if I use a prefix like you mentioned, for instance use the test class's name

io.dropwizard.configuration.ConfigurationValidationException: src/test/resources/dropwizard-test-config.yml has an error:
  * dataSourceFactory.url must not be empty

it complains that it needs to have url

I suppose "oh" means you got what was wrong

Eddie Xie

@oeddyo

let me try it out. was missing the "each" part

ah!

oh my god can't believe this is real

yes your solution works!

@oeddyo

amazing! Not going to be ass kissing but this guicey project is the most amazing one-man OS project I've seen lol

@xvik

thank you))

Hi @xvik ! I'm using a guava cache in my filter: ``` @Inject
private SessionFactory sessionFactory;

@Inject
public CredentialRequiredFilter(AppDao appDao, Cache<String, App> appCache) {
this.appDao = appDao;
this.appCache = appCache;
}
```

sorry gitter code format is always a mystery to me

now I'm trying to replace the cache with a mock cache in test. I saw in GuiceyHook it's possible but I'm using junit-5. Is there anything I can do now or shall I wait for your changes?

Vyacheslav Rusakov

@xvik

hi!

hooks is a generic mechanism:

GuiceyConfigurationHook hook  = builder -> builder.extensions(...);

here lambda used instead of direct inteface implementation

to register hook: hook.register()

there only problem is to register it before application startap

your junit extension use BeforeAll hook, so it is impossible to register anything beofre extension execution

so you will have to add hooks support inside your extension (to register them before startup)

Eddie Xie

@oeddyo

i see. I'll try out and see if I can get it work

Vyacheslav Rusakov

@xvik

and about formatting: just start ''' on new line. To activate syntax highlighting put language name after it like '''java

Eddie Xie

@oeddyo

ah ok
thanks

@oeddyo

neat!

Eddie Xie

@oeddyo

I seem to get it working in the extension via:

i pass the overrideModule in the extension's constructor, and in the overrideModule I override the cache I wanted to mock. from the guice print it seems to be overridden

does this sound reasonable?

Vyacheslav Rusakov

@xvik

yes ofc, report confirms that

Eddie Xie

@oeddyo

it works!

@xvik i had a suggestion to dropwizard core project to add the application build version during startup,which is rejected unfortunately..i want to know your opinion about this feature dropwizard/dropwizard#3331

Vyacheslav Rusakov

@xvik

I agree that it is too specific addition (and could be easily done in the application if required).

Fazeem Mohammed

@fazeem84

Ok.. thanks for your opinion :)

Hi @xvik I'm seeing my customized Exceptionmapper registered but it's not called when exception happens. The exception is thrown in one of the filter I created

Dynamic features
        CredentialRequiredFeature    (c.k.restful.filter)       
        LoginRequiredFeature         (c.k.restful.filter)       

    Exception mappers
        IndexNotFoundException         IndexNotFoundExceptionMapper (c.k.r.exceptionmapper)

ERROR [2020-06-16 18:22:29,915] io.dropwizard.jersey.errors.LoggingExceptionMapper: Error handling a request: c6536299f686a565

maybe I'm not registering it correctly?

        .extensions(
            AccountResource.class,

            IndexResource.class,
            DocResource.class,
            CredentialRequiredFeature.class,
            LoginRequiredFeature.class
        )

Eddie Xie

@oeddyo

ah I found it probably has something to do with the exception is thrown in the ContainerRequestFilter

if it's thrown elsewhere, the ExceptionMapper can actually catch it

Vyacheslav Rusakov

@xvik

hi @oeddyo ! Actually LoggingExceptionMapper (shown in error log) is the default dropwizard mapper, so mappers mechanism was used. It is better to debug exception handling to see why it choose default handler instead of your custom mapper. org.glassfish.jersey.internal.ExceptionMapperFactory#find(java.lang.Class<T>, T) - mapper selection logic

Eddie Xie

@oeddyo

@xvik looks like in the function you mentioned, it's trying to search for which is the most "suitable" exceptionMapper by looking at distance

Eddie Xie

@oeddyo

it's interesting... i didn't do anything new but now it seems be able to recognize the exp mapper :|

Eddie Xie

@oeddyo

hmm... it happened again. I'm throwing an exception in resource now, but for some reason the mapperFactory you mentioned keep finding the default mapper so my IndexNotFoundExceptionMapper is not used
