Create a ToDo Application Using SpringBoot

ToDo Application

We would like you to create a ToDo REST-Service Application.
Technology: Java, SpringBoot, SpringMVC, Hibernate, JPA, H2 Database 

Todo
{
    id [mandatory]
    name [mandatory]
    description
    tasks: [
        {
            id [mandatory]
            name [mandatory]
            description

    ]
}

The service shall support the following endpoints/rest-api:

GET /tasks/{id} -> Returns a Task
PUT /tasks/{id} -> Overwrites an existing Task

GET /todos/{id} -> Returns a Todo
GET /todos/{id}/tasks/id -> Returns a Todo with Task
PUT /todos/{id} -> Overwrites an existing Todo
DELETE /todos/{id} -> Deletes a Todo

Todos must be stored in the Database.
