I would be interested by the outcome

@sdeleuze Thanks for the hints, will try tomorrow. As for the class "openness" I thought that kotlin all open plugin handles this

allopen only acts on classes with certain annotations (https://kotlinlang.org/docs/reference/compiler-plugins.html#spring-support)

@sdeleuze Seems that problem lies in the initialization order/time. In my security config I have

authenticationProvider

that depends on

userDetailsServiceProvider

@get: Bean
val userDetailsServiceProvider = JdbcDaoImpl().apply { ... }

@get: Bean
val authenticationProvider = DaoAuthenticationProvider().apply {
        setUserDetailsService(userDetailsServiceProvider)
    }

And it seems that initialization of

authenticationProvider

forces

userDeatailsServiceProvider

bean creation in constructor

public Security(@Autowired @Qualifier("dataSource") @NotNull DataSource appDataSource) {
      Intrinsics.checkParameterIsNotNull(appDataSource, "appDataSource");
      super();
      // Some lines skipped
      DaoAuthenticationProvider var7 = new DaoAuthenticationProvider();
      var7.setUserDetailsService((UserDetailsService)this.getUserDetailsServiceProvider());  // This seems to be a problem
      this.authenticationProvider = var7;
      this.securityEvaluationContextExtensionProvider = new SecurityEvaluationContextExtension();
   }

And problem is cured by this change

val authenticationProvider
    @Bean get() = DaoAuthenticationProvider().apply {
        setUserDetailsService(userDetailsServiceProvider)
    }

This way initialization of

authenticationProvider

happens later on demand, when class is constructed and

BeanFactory

injected.

This also helps (obviously)

@get: Bean
val authenticationProvider by lazy {
    DaoAuthenticationProvider().apply {
        setUserDetailsService(userDetailsServiceProvider)
    }
}

Quick question from a spring boot noob. What is the best way to keep an arraylist in memory on a spring boot applic ation so that can be used throughout the application?

Ideally I would be able to load that arraylist on application startup

FYI start.spring.io now adds

jackson-module-kotlin

dependency when appropriate https://github.com/spring-io/initializr/commit/4d0fac5df0c5b12c86ee8174b1b03c0227e9b676

What’s the way to autowire dependencies into a kotlin test class?

Should I just do

@Autowired var dependency: Dependency? = null

? or is there a cleaner way.

(since that makes all the calls

?.

Hey, I need feedback on this : from my latest tests it seems

lateinit var

works nicely with

@ConfigurationProperties

. If that's true that would be super nice since Boot 2.0 will not support immutable data classes yet (2.1 should). Could you try the following approach with your projects and say me if I missed something of if it works as expected.

(instead of nullable

var

which I was using previously)

Some concrete applications and use cases would be interesting I think

Hi there, I'm having some trouble getting code that invokes Spring's JdbcOperations extensions to compile when working with variable arguments. Am I in the right place? 🙂

you're

show as an example

Not kotlin: But has anyone attempted to use Spring’s STOMP websocket along with a

selector

header in the subscription?

For some reason, Kotlin interprets the value in Spring's

@Import

as a single KClass, instead of an array of KClass

Hello everyone, I have a generics issue with Kotlin and Spring, not sure if this is a bug or I’m doing something wrong, I would appreciate if someone can take a look https://stackoverflow.com/questions/48921097/kotlin-generic-issue-should-be-subtype-of-nothing

Hey guys, I am creating a Kotlin based JHipster project. That includes creating awesome web application Spring boot 2 + Angular (or) react for the frontend. I want to achieve a completely Kotlin based application (incl frontend and backend). If anybody is interested to contribute come and join the fun at https://github.com/jhipster/jhipster-kotlin

Hi, seems that I find a problem in Spring kotlin interop. The example is https://gitlab.com/AleksandrSl/spring-sandbox/tree/data-rest-security-RC2.

-Xjsr305=strict

compiler argument that is added by spring initializr forces to override methods like

findById

the following way

override fun findById(id: Long): Optional<User>

. But it seems that this override is the wrong one, and it should be

override fun findById(id: Long?): Optional<User>

cause with the last one security annotations works the right way.

I've started integrating it in our production software at RC2. Will probably finish tomorrow 🙂

do you know of any json deserializer that doesn't need an empty constructor and calls it with all the given params?

Or Jackson with

jackson-module-kotlin

.

You don't need the annotation in most cases.
