http://dummy.restapiexample.com/api/v1/employees
Let's create a Spring Boot Camel microservice.
In the pom.xml of the microservice, add the dependency below:
XML
x

<dependency>
2
<groupId>org.apache.camel.springboot</groupId>
3
<artifactId>camel-http-starter</artifactId>
4
<version>3.8.0</version>
5
</dependency>
Configuring the REST Client Route in the Microservice
restConfiguration() is used to configure the host and the port.
The route is configured to run every 10 secs and call the REST API endpoint using the GET method.

Testing
Start the application. You can see that the timer is triggered every 10 secs, and the REST API endpoint is called.
