Generate REST API with CRUD operations

You can generate REST API with CRUD operation using the following command:

IMPORTANT: You should run the following command from within the generated project folder.

$ cd blog
$ yo springboot:controller Customer --base-path /api/customers

This sub-generator will generate the following:

• JPA entity
• Spring Data JPA Repository
• Service
• Spring MVC REST Controller with CRUD operations
• Unit and Integration Tests for REST Controller
• Flyway or Liquibase migration to create table

$ yo springboot:controller Customer --base-path /api/customers
