我正在尝试制作一个简单的播放框架应用程序来监视我的 aws ec2 实例。我一直在按照本指南开始。这是我遇到问题的方法。

public static AmazonEC2Client createClient(){
    String accessKey = "ACCESS_KEY";
    String secretKey = "SECRET_KEY";
    String endpoint = "ec2.us-east-1.amazonaws.com";

    BasicAWSCredentials credentials  = new BasicAWSCredentials(accessKey, secretKey);
    AmazonEC2Client ec2Client = new AmazonEC2Client(credentials);
    ec2Client.setEndpoint(endpoint);
    return ec2Client;
}

当该方法运行时，我收到此错误并且播放服务器停止。

我遇到了同样的错误。我更改了我的 Maven 依赖项的版本并解决了错误。

新依赖：

<dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk</artifactId>
            <version>1.4.3</version>
</dependency>

旧依赖：

<dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk</artifactId>
            <version>1.5.7</version>
</dependency>

此外，请确保从类路径中删除旧版本，因为如果您不这样做，它往往会选择最新版本。希望这可以帮助 ：）
