Apache Camel：如何创建 AWS SQS 并订阅 SNS 主题

Question

I want to create AWS SQS and then subscribe it to an existing SNS topic. For use this approach , from Camel documentation, I must know a queue URL.

//create SQS
from("aws-sqs://MyQueue?amazonSQSClient=#client&delay=5000&maxMessagesPerPoll=5")
.startupOrder(1)
.to("mock:result");

//create SNS and subscribe to SQS
from("direct:start")
.startupOrder(2)
.to("aws-sns://test-camel-sns1?amazonSNSClient=#amazonSNSClient&amazonSQSClient=#amazonSQSClient&subscribeSNStoSQS=true&queueUrl=https://sqs.eu-central-1.amazonaws.com/780410022472/MyQueue");

But I want to use previously created SQS (I know the name of SQS) and I don't know the account value(780410022472). How can I create SQS and subscribe to SNS without additional information(like an account value) by Camel?

Answer 1

If you have access to the AWS account via CLI, you could simply list all existing queues as follows:

aws sqs list-queues

This will return the SQS queue URLs as follows:

https://queue.amazonaws.com/80398EXAMPLE/MyQueue

In the above example, the account number would be 80398EXAMPLE .

You could also get the account details for the current IAM user/role using the following command:

aws sts get-caller-identity

This will return the account number with the Account field.
