java - 为什么 aws UploadFunctionResult 不起作用？

问题描述

我正在尝试从 dummylamda更新mylamda的代码，但我认为代码实现方法存在一些问题。

每当一个新的myobject.jar被上传到mybucket时，dummylamda就会被触发，这会将myobject.jar部署到mylambda。

当我编写此代码时，我无法导入正确的包。以下是规格：

https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/lambda/AWSLambda.html#updateFunctionCode-com.amazonaws.services.lambda.model.UpdateFunctionCodeRequest-

Java代码：

package com.amazonaws.lambda.dummy;

import com.amazonaws.AmazonWebServiceResult;
import com.amazonaws.ResponseMetadata;
import com.amazonaws.services.lambda.AWSLambda;
import com.amazonaws.services.lambda.AWSLambdaAsyncClient;
import com.amazonaws.services.lambda.AWSLambdaClient;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.lambda.model.UpdateFunctionCodeResult;

public class LambdaFunctionHandler  {

     UpdateFunctionCodeResult updateFunctionCode(UpdateFunctionCodeRequest updateFunctionCodeRequest)
       {
           AWSLambda client = AWSLambdaClientBuilder.standard().build();
           UpdateFunctionCodeRequest request = new UpdateFunctionCodeRequest().withFunctionName("mylambda-arn")
                    .withS3Bucket("mybucket-name").withS3Key("myobject-key")
                    .withPublish(true);
            UpdateFunctionCodeResult response = client.updateFunctionCode(request);

        return response;

       }   
}

解决方案

只需添加aws-java-sdk-bundle maveen 依赖项，并且需要更新其他依赖项的版本。因此，更新后的 POM 为：
