Building and testing customer service

Let's create builds for the Eureka server, customer, and Account service using the mvn clean install command and after that run all these services using the Java command. You can find customer service in port 6161. And Account service is available at port 6060. But we are using the Spring Cloud Eureka registry server, so you don't need to use the actual hostname and port to call Account service in the customer service, just use the logical service name (http://ACCOUNT-SERVICE).

Now fetch the customer service by opening the browser and type http://localhost:6161/customer/1001. It should show the following output in the browser:

As you can see in the preceding screenshot, the customer with the 1001 customer ID has been rendered with two accounts by calling the Account service internally by the customer service. So if both services are running fine, the customer service is displaying the data returned by the Account service. That means the circuit-breaker...
