- <strong>Customer</strong> class corresponds to entity and table <strong>customer</strong>.
- <strong>CustomerRepository</strong> is an interface extends <strong>MongoRepository</strong>, will be autowired in <strong>CustomerController</strong> for implementing repository methods and custom finder methods.
- <strong>CustomerController</strong> is a REST Controller which has request mapping methods for RESTful requests such as: <code>getAllCustomers</code>, <code>postCustomer</code>, <code>deleteCustomer</code>, <code>deleteAllCustomers</code>, <code>findByAge</code>, <code>updateCustomer</code>.
- Configuration for Spring Datasource and Spring Data properties in <strong>application.properties</strong>
- <strong>Dependencies</strong> for <strong>Spring Boot</strong> and <strong>MongoDb</strong> in <strong>pom.xml</strong>
