cd chapter-4-spring-data-r2dbc
./mvnw spring-boot:run

Try to get fruits by running the following command with curl:

curl http://localhost:8080/fruits

You should get two fruits:

[
    {
        "description": "Hearty fruit",
        "id": 1,
        "name": "Apple"
    },
    {
        "description": "Juicy fruit",
        "id": 2,
        "name": "Pear"
    }
]

You can also add a fruit by running the following command:

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"description":"Best fruit ever","name":"Watermelon"}' \
  http://localhost:8080/fruits
