jackson - KotlinデータクラスJackson @JsonPropertyが尊重されない

Question

Kotlin データ クラスを使用して Feign を POST に配線しています。

私が呼び出している API は、{..."brandInfo":{"TPID":1}...} を想定しています。

私の理解では、jackson-module-kotlin 依存関係が正しく取得されていない場合、Jackson エンコーディングが完全に失敗するため、Feign は POST をまったく実行できません。

ただし、Feign は POST でき、Jackson はエンコードできますが、何をしても、{..."brandInfo":{"tpid":1}...} が投稿されています。 @JsonProperty("TPID") で注釈が付けられています。

私は何が欠けていますか？

@JsonIgnoreProperties(ignoreUnknown = true)
data class KBrandInfo (
    @JsonProperty("TPID") //not honored
    val TPID: Long
)


interface KConversationServiceClient {
    @RequestLine("POST v2/conversations")
    @Headers("Content-Type: application/json")
    fun createConversation(createConversation: KCreateConversation): String
}


@Provides
public KConversationServiceClient getKConversationServiceClient(
        @Named("conversationServiceUrl") String baseUri,
        Feign.Builder builder) {
    return builder
            .logLevel(Logger.Level.FULL)
            .decoder(new StringDecoder())
            .encoder(new JacksonEncoder(jacksonObjectMapper())) //does this need some extra configuration in order to pick up @JsonProperty annotations?
            .requestInterceptor(requestTemplate ->
                    requestTemplate
                            .header("requestId", UUID.randomUUID().toString())
            .target(KConversationServiceClient.class, baseUri);
}
