Hi guys please i'm using the twilio API to send SMS I noticed that when i put the implementation under a Restcontroller in the Application.kt file just for test , it was able to send sms to my phone But when i moved the implementation to the controller package it gave me the error

The 'From' number xxx is not a valid phone number, shortcode, or alphanumeric sender ID.

//Controller
 @PatchMapping("/comment/{id}/")
    fun PatchCommentById(@PathVariable id: Long, @RequestBody comment: Comment): ResponseEntity<Comment> {
    
        val updatedComment = repo.save(Comment(
                id = id,
                body = comment.body,
                video_link = comment.video_link,
                image_link = comment.image_link,
        ))
        return ResponseEntity.ok(updatedComment)
    }

how would u partial update this?

how would you implement websockets into spring boot?

Hi All. I am getting build errors when using the following plugins:

id("io.spring.dependency-management") version "1.0.10.RELEASE"
id("org.springframework.boot") version "2.3.3.RELEASE"

Even without any Spring dependencies declared. If I don't include the dependency-management plugin, the errors do not occur. The errors are:

w: Runtime JAR files in the classpath should have the same version. These files were found in the classpath:

This was with a new Multiplatform Kotlin project created in IntelliJ, but just adding those 2 plugins to the build.gradle.kts. I think this is an issue with the Spring dependency-management plugin. I am not sure if this is the best place to ask for help with this, if it is a bug or something I am doing wrong. If I should file a bug report in another Spring channel, please advise where that should be. Thanks!

I don't know if this is the correct place to talk about this. I've started to use spring-auto-restdoc (third party project). It infers a property in the api is optional based on if its a nullable type. However I've got a few data classes that use default values, which are not marked as nullable. So from an API consumers point of view they are nullable. Whats the best way to approach this? Mark the values (

val

as nullable ). This leads to unnecessary null checks later. Or somehow change how Jackosn creates its

PropertyMetadata

object. --- I'm going to cross post to stack overflow.

Hello, the code completion plugin broke an unknown time ago for us for https://blog.jetbrains.com/idea/2018/10/kotlin-jpa-and-spring-data/ no longer do we get suggestions for repository extended classes, anyone know why?

Guess it would be easier to just make it open and make the setter private...

Hi guys, please maven is not running my tests. I have gone through google, but none of the solutions seems to be working

Requirekt provides idiomatic preconditions for spring boot. K🎉 The idiomaticity and power of kotlins 

require

 for spring boot rest API's. 👌 v1.1.0 now supports custom error responses! https://github.com/nextbss/requirekt

Hello guys please maven doesnt see and run junit4 tests in springboot please help, I have tried different configurations, please if anyone has done this before

so im trying to have a one to many and a many to one in the dto. should i create a separte dto for postmapping?

does it matter if i use a data class or class for my entity

hi guys i need to set based on a profile a environment variable (here https_proxy) for local development. any best practise for it ? (my idea so far is to set it within a @Configuration in the init block with ProcessBuilder, but no luck so far 😞 )

consider introducing proper tracing, not sure how it works with coroutines but it would be a better solution imo: https://spring.io/projects/spring-cloud-sleuth

Hi, does spring MVC support kotlinx.serialization library ? if yes, where can i find example using it instead of Jackson ?

is there ever a reason to use mutable list vs list in spring boot:?

so is there something in spring-init that looks like

fun makeFunctional(Class<?> configClass): (GenericApplicationContext) -> Unit

?

Is that kofu or it that part of spring boot now?

Looking forward to the coroutine support in Spring MVC - We can then finally get rid of our

runBlocking

"workaround" - thanks @sdeleuze ! Less Kotlin, probably more about Spring itself: We're also using functional routing for a year now and we're very happy with it. The only thing I miss is support for server side events for Spring MVC projects. The functional routing receives a

ServerRequest

and expects a

ServerResponse

in return but I don't see a way to incorporate to respond with the SseEmitter object that is used for SSE on Spring MVC. Am I missing something or should I open a ticket?

is Exposed the recommended ORM for Kotlin + Spring?

I am not sure how to look for this info without going through github issues, so maybe someone knows and can save me some time. assuming I have something like

class MyRestRepresentation(@get:NotBlank val notBlank: String)

and someone makes an http call like

POST { notBlank: null }

kotlin will throw an exception (jackson will actually) before validation happens. this messes up the error response a bit, since with javax validation we get a nice path to the property that fails validation oob, while otherwise we probably need to do it manually, if at all possible. is Spring working on something like doing validation before before or some other approach or is my best option to declare

notBlank

as

String?

and just read it as

notBlank!!

?

Hi. I'm using Spring Webflux and have controllers with suspending functions. I'd like to have all of those controller functions invoked with a coroutine that has an element within the coroutine context. The best I can think of so far is to manually add the context element as

withContext

inside each and every controller function - something like this:

@GetMapping("/foo")
    suspend fun getFoo(): Foo {
        withContext(SomeCoroutineContextElement()) {
            TODO("Do something")
        }
    }

Is there a better way - i.e. a way to add the context across all controller functions, so I don't need to litter every one of them with

withContext

?

I’m having trouble integrating Flux into my codebase:

val inputStream: InputStream = URL(attachmentURL).openStream()
val buffer = DataBufferUtils.readInputStream(
    { inputStream },
    DefaultDataBufferFactory(),
    8192
)

I’ve integrated the following dependency into my project:

implementation(group = "io.projectreactor", name = "reactor-core", version = "3.3.10.RELEASE")

But i’m getting this error:

Cannot access class 'reactor.core.publisher.Flux'. Check your module classpath for missing or conflicting dependencies

highlighted on readInputStream Am I missing something?

now i want to play with coroutines and change my

router

to a

corrouter

but the latter expects a

ServerResponse

, not a

Mono<ServerResponse>

every example i see the function that generates/read the data is

suspend

and returns

T

so shall i understand in that case,

corrouter

is not a good fit? or did i miss something?

Hi, i have Exceptions defined like this

const val reason = "store not found"
@ResponseStatus(code = HttpStatus.NOT_FOUND, reason = reason)
class StoreNotFoundException : RuntimeException()

but i want to log the error whenever its been throw

const val reason = "store not found"
@ResponseStatus(code = HttpStatus.NOT_FOUND, reason = reason)
class StoreNotFoundException : RuntimeException(){
    init {
        warningLog(reason)
    }

    companion object {
        private val logger = LoggerFactory.getLogger(CustomException::class.java)
        fun warningLog(message: String) {
            logger.warn(message)
        }
    }
}

i've implemented like this Since i have a lot of exceptions defined like this and i want to have the log whenever one is threw, how can i generalize this behavior? how can i write a CustomException?

Hi guys, is it possible to use kotlinx serialisation with spring boot?

Hi. What does

@EnableWebMvc

exist for? 🤔 I used this annotation. However, when I added

@EnableWebMvc

to some

Configuration

, the other

Configuration

seemed to be disabled...

I built API by using

@RestController

. And I called GET API via curl command with multibyte character query param. But I received 400 error (The valid characters are defined in RFC 7230 and RFC 3986). Do I need to set some Spring Boot config?
