1. Add class AccountsConstants provided to a new package com.tus.accounts.constants. This class will store error messages.
2. Update the AccountController class for the PostMapping as shown. You can add /accounts to the PostMapping path
3. Add a packages service and serviceImpl. These will hold the interface for the Service layer and its implementation. Note: don’t need to use @Autowired in Springboot 3.
4. We will now create a mapper class (code given) for AccountsMapper and CustomerMapper. This is to map data between the Entity classes and the DTO classes.
5. Update the AccountsServiceImpl with the method for creating a new account base on a CustomerDto object.
6. Update the controller to call the service layer
7. Run the project and check the h2-console. The tables should be created and empty.
8. Create a new customer from postman. You should get response code 201 and message as shown below.
9. Check that the data has been written to the database
