That provide the simple form + Kotlin displayed and pre-selected

Anyone know of a reason why the top delete override in this is acting weird?

eluinhost

Copy code

@RepositoryRestResource
interface MatchRepository : PagingAndSortingRepository<Match, Long> {
    @RestResource(exported = false) override fun delete(id: Long)
    @RestResource(exported = false) override fun delete(match: Match)
    @RestResource(exported = false) override fun delete(match: Iterable<Match>)
    @RestResource(exported = false) override fun deleteAll()
}

If it is there I get

PropertyReferenceException: No property delete found for type Match

and if I comment it out everything loads as usual

eluinhost

it's supposed to override

void delete(ID id);

CrudRepository<T, ID extends Serializable> extends Repository<T, ID>

but it doesn't seem like it gets detected properly

probably because

Long

is actually a

long

, try

Long?

instead

eluinhost

05/24/2016, 10:07 AM

yeah that fixed it :)

eluinhost

05/24/2016, 10:08 AM

Long?

keeps the representation as an object, whereas

Long

uses the primitive?

cleiter

05/24/2016, 10:09 AM

it's the most efficient way to map these types. non-nullable can be a

long

but if it can be null you need an object

eluinhost

05/24/2016, 10:09 AM

makes sense

cleiter

05/24/2016, 10:09 AM

you could also try with

java.lang.Long

but it's also not pretty 🙂

Hey @sdeleuze Thanks for the spring kotlin FAQ. It’s really informative and a great condensing of known issues/workarounds.

Just spotted it by looking at my history.

@dharrigan Thanks, glad it helps, I will try to update it as needed.

FYI we have maybe found a strange Kotlin bug with Spring MockMVC https://youtrack.jetbrains.com/issue/KT-12624

@sdeleuze: it's not a corrupted class. It's just an array of WelcomeController. And it's expected, since that's what you pass to standaloneMvcBuilders():

arrayOf(controller)

instead of just

controller

. It's a vararg method. You're not supposed to pass an array.

@sdeleuze: Any progress in reviewing https://github.com/spring-projects/spring-framework/pull/1060 ?

Could somebody from JetBrains unflag my https://discuss.kotlinlang.org/t/dependency-injection/138/12 comment ? It seems somebody have flagged it as spam (by mistake I assume given my comment)

(the comment was just "Constructor injection is also recommended with Spring, see this spring-kotlin FAQ entry for more details." with a link to https://github.com/sdeleuze/spring-kotlin#what-is-the-recommanded-way-to-inject-dependencies-in-a-spring-kotlin-application)
