Microservices with Camel Quarkus

This project shows four microservices implemented using Apache Camel on Quarkus, as follows:

• aws-camelk-file: this microservice is polling the /tmp/input local folder and, as soon as an XML file is comming, it store it in an AWS S3 bucket, which name starts with mys3 followed by a random suffix.
• aws-camelk-s3: this microservice is listening on the first found AWS S3 bucket which name starts with mys3 and, as soon as an XML file comes in, it splits, tokenizes and streams it, before sending each message to an AWS SQS queue, which name is myQue.
• aws-camelk-sqs: this microservice subscribes for messages to the AWS SQS queue named myQueue and, for each incoming message, unmarshall it from XML to Java objects, the marshal it to JSON format, before sending it to the REST service below.
• aws-camelk-jaxrs: this microservice exposes a REST API having endpoint for CRUDing money transfer orders. It consumes/produces JSON input/output data. It uses a service which exposes and interface defined by aws-camelk-api project. Several implementations of this interface might be present but, for simplicity sake, in the current case we're using the one defined by aws-camelk-provider project, named DefaultMoneyTransferProvider, which only CRUds the money transfer order requests in an in-memory hash map.
