如果您在将`NettyNioAsyncHttpClient`作为`SdkHttpClient`构建器时遇到`ClassCastException`异常,可能是由于错误的类型转换引起的。为了解决这个问题,您可以使用`SdkHttpClient.Builder`的`httpClientProvider`方法来设置`NettyNioAsyncHttpClient`。
请将代码片段中的`.httpClientBuilder(NettyNioAsyncHttpClient.builder())`替换为`.httpClientBuilder(builder -> builder.httpClientProvider(NettyNioAsyncHttpClient.builder()))`:
```java
S3Client s3Client = S3Client.builder()
.region(Region.US_WEST_2)
.credentialsProvider(DefaultCredentialsProvider.create())
.serviceConfiguration(s3Config)
.httpClientBuilder(builder -> builder.httpClientProvider(NettyNioAsyncHttpClient.builder()))
.overrideConfiguration(ClientOverrideConfiguration.builder()
.apiCallTimeout(Duration.ofSeconds(30))
.build())
.build();
```
这样,您将使用`NettyNioAsyncHttpClient`作为`SdkHttpClient`的提供者,而不是直接将`NettyNioAsyncHttpClient.builder()`作为构建器。
请确保您已经将适当的依赖项添加到您的项目中,以便能够使用`NettyNioAsyncHttpClient`。例如,在您的pom.xml文件中添加以下依赖项:
```xml
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>netty-nio-client</artifactId>
</dependency>
```
希望这可以帮助您解决问题!
