Localstack-通过java aws sdk访问SNS：NoSuchFieldError：ENDPOINT

问题描述

我正在玩在docker上运行的localstack实例。我尝试访问sns服务，但是在执行“ listTopics（）”或“ createtopic（）”之类的方法时收到错误我尚未在Google上找到任何帮助，所以可能有人知道这里出了什么问题吗？

错误：

我尝试通过java aws sdk访问localstack sns服务：

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-sns</artifactId>
    <version>1.11.875</version>
</dependency>

我的应用中引发错误的代码如下：

private String serviceEndpoint = "http://localhost:4566";
private String signingRegion = "eu-west-1";

@Bean
    public AmazonSNS getSnsClient() {
        AmazonSNS sns = AmazonSNSClient.builder().withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(serviceEndpoint,signingRegion)).withCredentials(new DefaultAWSCredentialsProviderChain()).build();

        System.out.println(sns.listTopics().toString());

        return sns;
    }

我正在使用此docker-compose文件在Docker上运行localstack：

version: '2.1'

services:
  localstack:
    container_name: "localstack"
    image: localstack/localstack-full
    network_mode: bridge
    ports:
      - "4566-4599:4566-4599"
      - "${PORT_WEB_UI-8080}:${PORT_WEB_UI-8080}"
    environment:
      - SERVICES=s3,sns
      - DEBUG=${DEBUG- }
      - data_dir=/tmp/localstack/data
      - PORT_WEB_UI=${PORT_WEB_UI- }
      - LAMBDA_EXECUTOR=${LAMBDA_EXECUTOR- }
      - KInesIS_ERROR_PROBABILITY=${KInesIS_ERROR_PROBABILITY- }
      - DOCKER_HOST=unix:///var/run/docker.sock

    volumes:
      - "local_vol:/tmp/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"
volumes:
  local_vol:
      driver: local

通过cmdline创建SNS主题可以正常工作，因此该服务正在运行！

/opt/code/localstack # aws --endpoint-url=http://localhost:4566 sns create-topic --name my_topic
{
    "TopicArn": "arn:aws:sns:us-east-1:000000000000:my_topic"
}
/opt/code/localstack # aws --endpoint-url=http://localhost:4566 sns list-topics
{
    "Topics": [
        {
            "TopicArn": "arn:aws:sns:us-east-1:000000000000:my_topic"
        }
    ]
}

顺便说一句：我也使用了本地股票的S3，这是可行的-无论如何这2个冲突？

希望有人可以帮助我解决此问题。：）

解决方法

使用AmazonRoute53Client时也遇到此错误。

检查后，HandlerContextKey类上没有ENDPOINT_OVERRIDDEN字段。

此类可在aws-java-sdk-core库中找到。从1.11.873开始添加了ENDPOINT_OVERRIDDEN。

解决方案： 将aws-java-sdk-core更新为最新版本或至少为1.11.873

Github source code

Library: aws-java-sdk-core for version 1.11.873

我也遇到了同样的问题。

错误来自使用2个不同的AWS库，每个库均依赖于不同的AWS开发工具包SDK核心版本。

我们需要确保版本号是一致的。他们每两天发布一次更新的版本：https://github.com/aws/aws-sdk-java/releases

将AWS依赖关系与Maven一起使用的推荐方法是使用BOM表，该BOM表将同步AWS依赖关系版本。详细信息：https://aws.amazon.com/blogs/developer/managing-dependencies-with-aws-sdk-for-java-bill-of-materials-module-bom/

如果有人碰到这个，我在这里找不到实际的问题，但是让它与适用于Java 2.0的Amazon Aws sdk一起工作。

            <groupId>software.amazon.awssdk</groupId>
