What is the equivalent of

Copy code

springBoot {
    executable = true
}

in kotlinGradleDsl

Copy code

configure<SpringBootPluginExtension> {
    executable = true
}

Thanks @madhead actually I already tried

Copy code

configure<SpringBootPluginExtension> {
    isExecutable = true
}

but the build file doesn't compile (can't find the class SpringBootPluginExtension)

@xantier We provide cookie support on client side, and annotation based server, but not yet on functional API side, good catch. Could you create an feature request on https://jira.spring.io/browse/SPR/ asking for cookie support on WebFlux functional API ?

Looking for a cleaner way to access custom properties, seems like

lateinit

is not playing well when spring is reading and initialising properties via

yaml

. I have a class

Copy code

@ConfigurationProperties("maintenance")
class MaintenanceProperties {
var foo : String ? = null 
}

when we change it to => lateinit var foo :     String , kotlin gives us runtime error lateinit property foo has not been initialized

Without

lateinit

The way I am forced to access it is

properties.foo!!

,one way to get rid of

!!

is to perform a null check but this approch doesn't work well when we have nested properties (we end up with ugly null checks). Is there a better way to get rid of

!!

and make the application failed during startup if the property is not defined ?

@nklmish: I don't think there's a better way right now other than initializing your variables. I think @sdeleuze is working on it -> https://github.com/spring-projects/spring-boot/issues/8762 ?

@rpalcolea thanks man

Yeah no better approach for now, but I am doing good progress on https://jira.spring.io/browse/SPR-15673 and my goal is to have https://github.com/spring-projects/spring-boot/issues/8762 fixed for Spring Boot 2.0. That may be non-trivial but I will do my best to work with Spring Boot team to fix that. Current behavior is a pain clearly.

I am using Gradle 4.0 with IDEA 2017.1.4; but I got:

Configuration problem: @Configuration class 'Configuration' may not be final. Remove the final modifier to continue.

when I debug; I have used kotlin-allopen plugin

sdeleuze

07/05/2017, 1:13 PM

Make sure to use the

kotlin-spring

variant which is preconfigued with Spring annotatons, see https://kotlinlang.org/docs/reference/compiler-plugins.html#kotlin-spring-compiler-plugin. Also IDEA make sure to refresh Gradle config and run a full rebuild.

Anyone had any luck using BeanPropertyRowMapper with JdbcTemplate?

the.fine

07/06/2017, 4:18 AM

Trying to use it with a data class, couldnt figure it out

sdeleuze

07/06/2017, 8:24 AM

Could you share a repro project of the issue ? We plan to support Kotlin data classes in Spring 5 so that could help us.

the.fine

07/06/2017, 9:45 AM

Sure, will share something soon

Hey @sdeleuze, here is a repo that reproduces this issue https://github.com/the-fine/springBootKotlinJdbcTemplate

And what is the problem?

the.fine

07/06/2017, 12:45 PM

It expects a default constructor or no argument constuctor, which kinda misses the point in case of a data class in kotlin

dh44t

07/06/2017, 12:47 PM

But your properties are read only

dh44t

07/06/2017, 12:48 PM

did you tried with vars?

the.fine

07/06/2017, 1:02 PM

It should work, but this way you miss the immutability

dh44t

07/06/2017, 1:04 PM

Then use a normal RowMapper

the.fine

07/06/2017, 1:05 PM

Already did, i was thinking it might be possible to use it

the.fine

07/06/2017, 1:08 PM

Is there any example of it with Spring 5?

dh44t

07/06/2017, 1:09 PM

let me check

07/06/2017, 1:27 PM

Ive done it in a similar way. I was thinking that the propertyRowMapper will remove the need of mapping the result set to the object :)

the.fine

07/06/2017, 1:27 PM

Lazy me 😁

@sdeleuze can you think of a walk around with this?

sdeleuze

07/06/2017, 2:04 PM

For now using the function variant as suggested by @dh44t is probably the best way to handle that. I need to have a deeper look with Spring Framework team for native support, I tend to think that will be supported but no commitment yet.
