调用用Micronaut编写的AWS Lambda时出现NoSuchBeanException

问题描述

我已经用https://www.raywenderlich.com/5777183-write-an-aws-lambda-function-with-kotlin-and-micronaut作为指南在Kotlin中编写了一个简单的lambda。我的测试在本地通过。

但是，在将影子生成的胖罐子上载到AWS，运行时设置为 Java 11（Corretto）并使用io.micronaut.function.aws.MicronautRequestStreamHandler处理程序执行时，出现以下异常：

No bean of type [io.micronaut.function.LocalFunctionRegistry] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).: io.micronaut.context.exceptions.NoSuchBeanException

我想念什么？

项目结构如下：

                        └── ServiceTest.kt

重要代码：

// application.yml
micronaut:
  application:
    name: app

data class HandlerInput(var parameters: String)
data class HandlerOutput(val parameters: String,val result: String)
class Service() {
    fun execute(parameters: String): String {
        return "Not yet implemented"
    }
}

@FunctionBean("app")
class AppFunction : Function<HandlerInput,HandlerOutput> {
    private val service: Service = Service()

    override fun apply(input: HandlerInput): HandlerOutput {
        return HandlerOutput(input.parameters,service.execute(input.parameters))
    }
}
