Question

我有一个超级简单的mvn项目，该项目正在运行一些代码，以根据arn获取Lambda函数的标签。

public static void listTag(String lambdaArn) {
        final AWSLambdaAsync lambdaClient = AWSLambdaAsyncClientBuilder.standard()
             .withRegion(Regions.EU_WEST_1)
             .build();
        final ListTagsRequest listTagsRequest = new ListTagsRequest();
        listTagsRequest.setResource(lambdaArn);
        final ListTagsResult listTagsResult = lambdaClient.listTags(listTagsRequest);
        final Map<String, String> tags = listTagsResult.getTags();
        ...
}

代码运行正常，我可以获取标签。如果我在Spring Boot应用程序的@RestController类中的方法中调用完全相同的代码，则该代码不再起作用，并且继续显示以下内容：

我当然尝试在构建客户端时添加凭据，

.withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials("accessKey", "secretKey")))

该库的版本和Java都相同。 Spring Boot的版本为2.1.3.RELEASE（如果可能的话）。

我有同样的问题。我解决了直接在项目的httpclient中添加pom.xml。

<dependency>
   <groupId>org.apache.httpcomponents</groupId>
   <artifactId>httpclient</artifactId>
   <version>4.5.5</version>
</dependency>

Spring Boot依赖于该库的另一个版本。您需要将aws-java-sdk-core库所需的模块版本添加到pom.xml。

从Spring Boot运行时，AWSLambdaException和InvalidSignatureException
