运行graals原生spring云函数示例

Question

我尝试在spring-graals中运行aws函数示例，'java‘版本运行良好，但当我测试’原生‘版本时，我在控制台中看到以下错误。

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationContextInitializer : org.springframework.cloud.function.adapter.aws.CustomRuntimeInitializer
    at org.springframework.boot.SpringApplication.createSpringFactoriesInstances(SpringApplication.java:445)
    at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:427)

该示例将这些步骤记录到output.txt中，我在其中看到了以下几行。

WARNING: Could not register reflection metadata for org.springframework.cloud.function.adapter.aws.CustomRuntimeInitializer. Reason: java.lang.NoClassDefFoundError: org/springframework/cloud/function/web/source/DestinationResolver.

spring-graals-native版本为0.70.BUILD-SNAPSHOT.jar

快照版本为3.1.0- spring-cloud-function

pom文件可以是found here。

此外，在亚马逊网络服务控制台中，我只能使用类型为FunctionInvoker的处理程序进行测试，而不能使用SpringBootApiGatewayRequestHandler。

需要添加以下依赖项才能成功编译本机映像。

<!-- Required by DestinationResolver -->
       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

<!-- "spring-cloud-function-adapter-aws" coupled with webFlux-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-function-web</artifactId>
        </dependency>
