找不到类:org.springframework.cloud.function.adapter.aws.Function

Question

我使用的是Springcloud函数版本3.2.6。我已经在S3 bucket中上传了jar的zip文件，然后尝试使用S3 URI上传到AWS Lambda。在成功更新jar之后，我得到了以下错误。

{
"errorMessage": "Class not found: 
org.springframework.cloud.function.adapter.aws.FunctionInvoker",
"errorType": "java.lang.ClassNotFoundException"
}

我正在使用最新版本的spring-cloud函数，并尝试在AWS lambda中运行它。一些函数调用程序类不存在的原因。请告诉我我缺少什么。

Answer 1

该问题与包装无关。这有点奇怪，因为当zar被推到S3时，S3引用被赋予了它不调用的lambda。但是，如果您直接将jar添加到lambda中，那么它就会调用并像魅力一样运行lambda。

Answer 2

也许是包装有问题。请以其中一个样品为出发点-https://github.com/spring-cloud/spring-cloud-function/tree/3.2.x/spring-cloud-function-samples此外，请快速启动-https://docs.spring.io/spring-cloud-function/docs/current/reference/html/aws.html#_getting_started

Answer 3

问题是使用aws-sam 的包装

sam构建将生成：function-sample-aws-0.0.1-SNAPSHOT.jar

mvn包将生成：function-sample-aws-0.0.1-SNAPSHOT-aws.jar

如果手动上传到s3，-aws版本可以正常工作，但这并不实用。

我自己刚刚遇到了这个，正要去寻找解决方案
