AWS-从EC2连接到SQS

我正在使用以下代码获取AWS凭据以连接到SQS。这是我的个人凭据,当我在qa或prod env中部署此代码时,我不应该使用凭据连接到SQS。此代码将在AWS中的EC2容器中运行。我可以使用哪些选项连接到SQS,而不必像下面那样明确提供用户id/密码?

@Bean
public AWSCredentialsProvider awsCredentialsProvider() {

    ProfileCredentialsProvider profileCredentialsProvider = new ProfileCredentialsProvider(credentialsProvider);
    try {
        profileCredentialsProvider.getCredentials();
    } catch (Exception e) {
        throw new AmazonClientException(
                "Cannot load the credentials from the credential profiles file. " +
                        "Please make sure that your credentials file is at the correct " +
                        "location (~/.aws/credentials), and is in valid format.",
                e);
    }
    return profileCredentialsProvider;
}
