Kotlinで@Serviceを使用すると例外がスローされます

Question

KotlinでSSMプロジェクトを作成していますが、これは、クラス（サービス実装）に@Serviceで注釈を付けようとしている限り発生します。

1. 代わりにJavaでこの実装クラスをコーディングしようとしましたが、すべて正常に機能しました。
2. 必要なオーバーライドメソッドのみを保持しようとしました。
3. openはすでに追加されています。
4. context:component-scanが構成されています。

追加情報：

相対構造

- src
  - kotlin
      - service
        An interface
        - impl
          -> The implementation <-

spring-service.xml

<context:component-scan base-package="service" />

必要なメソッドのみを保持しようとしました

@Service
open class SeckillServiceImpl : SeckillService {
    override fun getAll(): List<Seckill> {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }

    override fun getById(seckillId: Long): Seckill? {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }

    override fun exportSeckillUrl(seckillId: Long): SeckillUrlExposer {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }

    override fun doSeckill(seckillId: Long, userPhone: Long, md5: String?): SeckillExecutionResult {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }
}

何が問題で、どうすればよいですか？ありがとう！

Answer 1

Kotlinの リフレクション機能 Springに必要なものは、別のJARで出荷されます。ビルドに追加してみてください。

build.gradle：

compile 'org.jetbrains.kotlin:kotlin-reflect:1.1.51'

pom.xml：

<dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-reflect</artifactId>
    <version>1.1.51</version>
</dependency>
