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：我试图将我的 lambda 代码引用到CDK代码中，但是java.lang.ClassNotFoundException当我尝试在AWS Lambda Console上测试它时它会抛出。

我添加了一些代码以供参考。这些类存在于同一个包中。

LambdaFunctionHandler 班级 ：

拉姆达代码：

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();
    }
}

创建部署包后它就起作用了。
