@sdeleuze i'd like to register an exception handler that transforms an exception into a json response.

for example, I'd like to create a custom WebExceptionHandler that upon receiving an exception e.g. Exception("oh snap! something went wrong"), it return a json response e.g.

 {
   "code": "internal_server_error",
   "message": "oh snap something went wrong"
}

i see the default exception strategy does this

public Mono<Void> handle(ServerWebExchange exchange, Throwable ex) {
	if (ex instanceof ResponseStatusException) {
		exchange.getResponse().setStatusCode(((ResponseStatusException) ex).getStatus());
		logger.debug(ex.getMessage());
		return exchange.getResponse().setComplete();
	}
	return Mono.error(ex);
}

All in all, its not clear to me how to respond with json from the exception handler. It seems like i must transform the exception into a DataBuffer, however this seems fairly complicated.

Any ideas? An example would be greatly appreciated!

Also, thanks so much for this example project. I've found it super helpful.

Hello,
can i define the configuration properties in a functional way?

Thanks

Hey @sdeleuze, thank you for cool project.
I have question about CORS in your Netty configuration by Kotlin DSL - could you add CORS filter in project?

Thanks

I download this code,and the build.gradle.kts file was all red ,idea prompt unresolved reference:kotlin,can you tell me why,thank you !

Add MongoDB Reactive support by providing a functional alternative to <repositories base-package="com.acme.repositories" /> in order to register MongoRepositoryFactoryBean (and possibliy other required beans). This could be maybe integrated in Spring Data natively later.

Pull requests welcomed!

Running the commands given for building and running:

1. ./gradlew clean build shadowJar
2. java -jar build/libs/spring-kotlin-functional-1.0.0-SNAPSHOT-all.jar

Results in:

no main manifest attribute, in build/libs/spring-kotlin-functional-1.0.0-SNAPSHOT-all.jar

Can the more best way of this code?

fun router() = router {
GET("/{a}", proxyHandler::redirect)
GET("/{a}/", proxyHandler::redirect)
GET("/{a}/{b}", proxyHandler::redirect)
GET("/{a}/{b}/", proxyHandler::redirect)
GET("/{a}/{b}/{c}", proxyHandler::redirect)
GET("/{a}/{b}/{c}/", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}/", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}/{e}", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}/{e}/", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}/{e}/{f}", proxyHandler::redirect)
GET("/{a}/{b}/{c}/{d}/{e}/{f}/", proxyHandler::redirect)
POST("/{a}", proxyHandler::redirect)
POST("/{a}/", proxyHandler::redirect)
POST("/{a}/{b}", proxyHandler::redirect)
POST("/{a}/{b}/", proxyHandler::redirect)
POST("/{a}/{b}/{c}", proxyHandler::redirect)
POST("/{a}/{b}/{c}/", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}/", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}/{e}", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}/{e}/", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}/{e}/{f}", proxyHandler::redirect)
POST("/{a}/{b}/{c}/{d}/{e}/{f}/", proxyHandler::redirect)

The link leads to https://github.com/sdeleuze/spring-kotlin-functional/blob/master/src/main/kotlin/micro/Beans.kt which gives 404. Maybe this is the right one ? https://github.com/sdeleuze/spring-kotlin-functional/blob/master/src/main/kotlin/functional/Beans.kt
