java - 如何在 AWS Java SDK v2 Apache 客户端上设置代理

Question

看起来没有关于如何做到这一点的好的来源，我找到信息的两个地方如下:

First link .这看起来是最新的版本。但是，即使我有依赖项，我也无法在项目的任何位置找到 software.amazon.awssdk.http.apache.ApacheHttpClient。

 <groupId>software.amazon.awssdk</groupId>
  <artifactId>aws-sdk-java</artifactId>
  <version>2.3.2</version>
</dependency>
<dependency>
    <artifactId>aws-http-client-apache</artifactId>
    <groupId>software.amazon.awssdk</groupId>
    <version>2.0.0-preview-1</version>
</dependency>

second link看起来提供了一个关于如何配置客户端的过时版本。示例中的以下代码看起来无效:

DynamoDBClient client =
        DynamoDBClient.builder()
                      .httpConfiguration(ClientHttpConfiguration.builder()
                                                                .httpClientFactory(apacheClientFactory)
                                                                .build())
                      .build();

ClientHttpConfiguration 不可用并且 httpConfiguration 方法在客户端不可用。

尝试一起破解一些东西给了我以下代码:

ProxyConfiguration proxyConfiguration = ProxyConfiguration.builder().endpoint(URI.create("host:port")).username("usr").password("pwd").build();

SdkHttpClient apacheClientFactory =
        ApacheSdkHttpClientFactory.builder()
                .socketTimeout(Duration.ofSeconds(10))
                .connectionTimeout(Duration.ofMillis(750))
                .proxyConfiguration(proxyConfiguration).build().createHttpClient();


this.s3client = S3Client.builder().httpClient(apacheClientFactory).build();

这可以编译，但我得到很多 java.lang.ClassNotFoundException: software.amazon.awssdk.http.ExecutableHttpRequest 异常，我不明白它们来自哪里或如何修复。

So my question is what is the correct way to setup a proxy for the 2.3.2 version of AWS Java SDK v2 and why is my implementation not working?

更新

当我添加以下依赖项时，出现另一个错误:

<dependency>
  <groupId>software.amazon.awssdk</groupId>
  <artifactId>apache-client</artifactId>
  <version>2.3.2</version>
</dependency>

错误:

Caused by: java.lang.ClassNotFoundException: software.amazon.awssdk.http.SdkHttpClient$Builder

Answer 1

您似乎引入了多个版本的 AWS SDK for Java。尝试使用像这样使用导入范围的“Bill of Materials”BOM 方法:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>software.amazon.awssdk</groupId>
      <artifactId>bom</artifactId>
      <version>2.5.60</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

有了定义，带上你想要的特定部分:

<dependencies>
    <dependency>
        <groupId>software.amazon.awssdk</groupId>
        <artifactId>iam</artifactId>
    </dependency>
    <dependency>
      <groupId>software.amazon.awssdk</groupId>
      <artifactId>apache-client</artifactId>
    </dependency>
</dependencies>

您无需指定版本，因为 BOM 涵盖了这些版本。正确设置依赖项后，您可以执行以下操作:

  final SdkHttpClient httpClient = ApacheHttpClient.builder()
            .proxyConfiguration(ProxyConfiguration.builder()
                    .useSystemPropertyValues(true)
                    .build())
            .build();
  this.s3client = S3Client.builder().httpClient(httpClient).build();

我正在使用 useSystemPropertyValues 以便它会获取 standard system properties为方便起见设置代理值。所有这些对我们都有效，并且代理被正确使用。
