public AmazonClient() {

}

@PostConstruct
private void initializeAmazon() {
    AWSCredentials credentials = new BasicAWSCredentials(this.accessKey, this.secretKey);
    this.s3Client = new AmazonS3Client(credentials);
}

amazonProperties:
  endpointUrl: https://s3.eu-central-1.amazonaws.com
  accessKey: XYZ
  secretKey: XYZ
  bucketName: XYZ

当我用 mvwn 启动我的应用程序时，一切正常。当我运行我的测试时，我得到以下异常：
