有没有一种方法可以在不编写原始sql语句的情况下将注释添加到由slick形成的sql中？这是为了跟踪启动sql的应用程序中的代码。
我在EC2上运行了一个长时间运行的工作进程,该进程使用来自SQS队列的项目.过了一段时间(8-12小时,我估计)我开始得到过期的安全令牌错误.我希望aws lib能够自动处理凭证刷新,但似乎并非如此.无论如何在客户端内处理？仅当我使用DefaultCredentialsProviderChain生成访问时才会发生这种情况.与密钥和密钥一起使用时不会发生此错误.堆栈跟踪如下:
com.amazonaws.AmazonServiceException: The security token included in the request is expired (Service: AmazonSQS; Status Code: 403; Error Code: ExpiredToken; Request ID: 6ff6e1a0-d668-5ac5-bcd7-ae30058f25c0)

我发现的解决方法是每次遇到过期令牌错误时更新awsCredentials并重置sqs客户端.
awsCredentials = (new DefaultAWSCredentialsProviderChain).getCredentials
sqs = SimpleSQSClient(awsCredentials, Regions.US_EAST_1)
queueSQS = sqs.simple(QueueName(queueName), true)
