I'm afk but I got an error trying to deserialize a Kotlin data class using the ChatClient's entity(Class<T>) method
Comment From: mxsl-gr
try register jackson kotlin module, at least it works for me. essentially kotlin's data class compiles into a class with a full-parameter constructor. register relevant module should resolve the issue
add dependency:
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-kotlin</artifactId>
</dependency>
ObjectMapper register module:
OBJECT_MAPPER.registerModule(new KotlinModule.Builder().build())

Recent work in this area for kotlin support. Need to retry on latest code base.

@joshlong there is now dedicted kotlin support can you try again. clikc on the kotlin tab on https://docs.spring.io/spring-ai/reference/api/functions.html for some additional information

package com.example.demo
import org.springframework.ai.chat.client.ChatClient
import org.springframework.aot.hint.annotation.RegisterReflectionForBinding
import org.springframework.boot.ApplicationRunner
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.context.support.beans
@SpringBootApplication
@RegisterReflectionForBinding(Joke::class)
class DemoApplication
fun main(args: Array<String>) {
runApplication<DemoApplication>(*args) {
val ctx = beans {
bean {
val cb = ref<ChatClient.Builder>()
return@bean cb.build()
}
bean {
ApplicationRunner {
val cc = ref<ChatClient>()
val joke = cc
.prompt("tell me a joke")
.call()
.entity(Joke::class.java)
println(joke)
}
}
}
addInitializers(ctx)
}
}
data class Joke(val setup: String, val punchline: String)
This basic thing works with boot 3.4 snapshot and spring ai 1.0.0 snapshots! :) Nice! I can't wait to try some of the other things Sebastien worked on

One thing that doesn't appear to work is using a reified generic variable , eg
val joke = cc
.prompt("tell me a joke")
.call()
.entity<Joke>()
Looks like we need n extension function for this. :) I'll craft a PR?
