Hi guys

How do I access arrays from configuration in spring? This doesn’t work:

private fun ssoFilter(): Filter {
        val filters = oauth2().map { ssoFilter(it, "/login/${it.name}") }
        // filters are always empty :(
        val filter = CompositeFilter()
        filter.setFilters(filters)
        return filter
    }

    data class OAuth2Service(
        val name: String = "",
        val client: OAuth2ProtectedResourceDetails = AuthorizationCodeResourceDetails(),
        val resource: ResourceServerProperties = ResourceServerProperties()
    )

    @Bean
    @ConfigurationProperties("oauth2")
    open fun oauth2() = ArrayList<OAuth2Service>()

oauth2:
  - name: facebook
    client:
      clientId: 12312
      clientSecret: 213123
      accessTokenUri: <https://graph.facebook.com/oauth/access_token>
      userAuthorizationUri: <https://www.facebook.com/dialog/oauth>
      tokenName: oauth_token
      authenticationScheme: query
      clientAuthenticationScheme: form
    resource:
      userInfoUri: <https://graph.facebook.com/me>

  - name: github
    client:
      clientId: 12312
      clientSecret: 21312312
      accessTokenUri: <https://github.com/login/oauth/access_token>
      userAuthorizationUri: <https://github.com/login/oauth/authorize>
      clientAuthenticationScheme: form
    resource:
      userInfoUri: <https://api.github.com/user>

I tried to bind single element and it worked, but array is always empty

hi guys

how to get rid of this warning? http://take.ms/075om

that’s how I use this property

@Configuration
open class GoogleApiConfiguration {
  @Value("\${google.maps.apiKey}")
  lateinit var apiKey: String
…
}

I think is just IntelliJ

nothing bad with your project, just IntelliJ’s spring boot support being picky

@dstarcev: have you tried oauth2[0] and oauth2[1]?

@corneil: the oauth2 function returned empty array

I had to create a wrapper class handling this part of the configuration

@dstarcev: In the examples from http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html I see you can add \@EnableConfigurationProperties(OAuth2Service.class) I am not sure if that will load an array of OAuth2Service the example has an array of String which doesn't require extra annotation.

Did you create a wrapper that contains array or list of OAuth2Service?

@corneil: yes I did

that’s what I ended with:

data class OAuth2Service(
        var name: String = "",
        val client: OAuth2ProtectedResourceDetails = AuthorizationCodeResourceDetails(),
        val resource: ResourceServerProperties = ResourceServerProperties()
    )

    data class OAuth2ServicesCollection(val services: List<OAuth2Service>)

    @Bean
    @ConfigurationProperties(prefix = "oauth2")
    open fun oauth2() = OAuth2ServicesCollection(mutableListOf<OAuth2Service>())

Maybe it is worth reporting to the spring team.

Notice, that I also had to define

name

as a variable and make the inner list mutable

howdy spring kotlingers

i'm trying to convert my spring rest docs to kotlin

having troube with generics here:

@Before public void setUp() { this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context) .apply(documentationConfiguration(this.restDocumentation)).build(); }

can any kind soul help me ?

@User uploaded a file:

Seems like you need to add a type to apply function

like apply<T> but with the expected type

Kotlin is pickier with generics
