在 AWS CDK 代码中引用 Lambda 代码时出现 java.lang.ClassNotFoundException

Question

我是 AWS CDK 的新手。

问题：我正在尝试将我的 lambda 代码引用到 CDK 代码中，但是 当我尝试在 AWS Lambda 控制台上对其进行测试时，它会抛出 java.lang.ClassNotFoundException。

我添加了一些代码供参考。这些类存在于同一个包中。

LambdaFunctionHandler 类：

Lambda 代码：

package com.myorg;

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;

public class LambdaFunctionHandler implements RequestHandler<String, String> {

    public String handleRequest(String event, Context context) {
        context.getLogger().log("Received event: " + event);
        return "Hello from lambda "+event;

    }

}

CDK 代码：

package com.myorg;

import software.amazon.awscdk.core.Construct;
import software.amazon.awscdk.core.Stack;
import software.amazon.awscdk.core.StackProps;
import software.amazon.awscdk.services.lambda.Code;
import software.amazon.awscdk.services.lambda.Function;
import software.amazon.awscdk.services.lambda.Runtime;

public class CdkProjectStack extends Stack {
    public CdkProjectStack(final Construct scope, final String id) {
        this(scope, id, null);
    }

    public CdkProjectStack(final Construct scope, final String id, final StackProps props) {
        super(scope, id, props);

        // The code that defines your stack goes here
        final Function hello = Function.Builder.create(this, "HelloHandler")
                .runtime(Runtime.JAVA_8)   
                .code(Code.fromAsset("src/main/java/com/myorg"))  
                .handler("com.myorg.LambdaFunctionHandler::handleRequest")        
                .build();
    }
}

创建部署包后它工作了。
