无法从类路径上的/AwsCredentials.properties文件加载AWS凭据

Question

使用此代码设置类路径

AWSCredentialsProvider credentialsProvider = new ClasspathPropertiesFileCredentialsProvider();
ec2 = new AmazonEC2Client(credentialsProvider);

以下是AwsCredentials.properties文件的格式

# Fill in your AWS Access Key ID and Secret Access Key
# http://aws.amazon.com/security-credentials
accessKey = keyHere
secretKey = secretKeyHere

以下是我得到的例外情况

Exception in thread "main" com.amazonaws.AmazonClientException: Unable to load AWS credentials from the /AwsCredentials.properties file on the classpath

    at com.amazonaws.auth.ClasspathPropertiesFileCredentialsProvider.getCredentials(ClasspathPropertiesFileCredentialsProvider.java:81)
    at com.amazonaws.services.ec2.AmazonEC2Client.invoke(AmazonEC2Client.java:8359)

Answer 1

我使用不同的方法建立了连接:

BasicAWSCredentials credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY);
AmazonDynamoDBClient client = new AmazonDynamoDBClient(credentials).withRegion(Regions.US_EAST_1);
DynamoDB dynamoDB = new DynamoDB(client);

可以在Identity and Access Management控制台中创建访问密钥和密钥.我希望它有所帮助......

Answer 2

您可以使用DefaultAwsCredentialsProviderChain()

根据文档!http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/DefaultAWSCredentialsProviderChain.html

AWS凭证提供程序链,按此顺序查找凭据:

1. 环境变量 - AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY(推荐,因为它们是由所有AWS SDK和除了.NET CLI识别),或AWS_ACCESS_KEY和AWS_SECRET_KEY(仅Java SDK中识别)
2. Java系统属性 - aws.accessKeyId和aws.secretKey
3. 凭据配置文件位于所有AWS开发工具包和AWS CLI共享的默认位置(〜/ .aws/credentials)
4. 通过Amazon EC2元数据服务提供的实例配置文件凭据

Answer 3

AWSCredentialsProvider credentialsProvider = new ProfileCredentialsProvider();
new AmazonEC2Client(credentialsProvider)

.aws /凭证

[default]
aws_access_key_id =
aws_secret_access_key = 

Answer 4

您收到此异常是因为您的AWS开发工具包无法加载您的凭据.您应该做的是转到首选项然后转到AWS并添加您的密钥和访问密钥.这样您的项目就可以检索这两个键.

Answer 5

试试这个文件格式：

[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>

我使用 ProfileCredentialsProvider() 将此文件保存为 ~/.aws/credentials。
