####Simple application with Spring boot using a configurable embedded/external DB datasource and RESTful calls that demonstrate how Guava Eventbus can be used to intercept invocations.

Here

1. A POST call to localhost:8080/customer/

with json data like {"id":"501","owningCustomer":{"id":"1001","name":"John Lennon"}}

will result in a adding a bank account to a customer.

2. A GET call to localhost:8080/customer/1001

will result in getting customer of id=101 and will result in producing { "id": "1001", "name": "George Harrison1-JPA", "bankAccounts": "[501, ]" }

A log message is printed out when a new account is added using the POST request and that event is logged using the EventBus api.
