== OpenAPI Contract First - Spring Boot example

=== Abstract

This example uses Camel to expose REST APIs from an existing OpenAPI specification (contract first).

=== Introduction

From the contract we generate Java POJO classes (using maven plugin, see `pom.xml`).

In the Camel route `PetStoreRoute.java` we use Rest DSL using OpenAPI in contract-first mode.
This makes it possible to expose all the APIs very easily, and map this to corresponding Camel
routes via `direct:operationId` naming convention.

The example uses the Petstore OpenAPI example which comes with 18 APIs. This example has only
implemented 2 of these APIs, and to ignore the remaining APIs. This is handy during development,
so you can implement the APIs one by one.

=== How to run

You can run this example using

    mvn spring-boot:run

=== To call the API

You can call the Rest APIs such as

----
curl http://0.0.0.0:8080/api/v3/pet/123
----

Which returns information about a pet.

You can also update an existing PET such:

----
curl -XPUT -H "Content-Type: application/json" --data "@daisy.json" http://0.0.0.0:8080/api/v3/pet
----


=== Camel CLI

This application is integrated with the Camel CLI (camel-jbang) via the `camel-cli-connector-starter` dependency (see `pom.xml`).
This allows to use the Camel CLI to manage this application, such as:

    $mvn spring-boot:run

And then use the CLI to see status:

    $camel get
      PID   NAME           CAMEL  PLATFORM            PROFILE  READY  STATUS   RELOAD  AGE  ROUTE  MSG/S  TOTAL  FAIL  INFLIGHT  LAST  DELTA  SINCE-LAST
     87918  CamelPetStore  4.6.0  Spring Boot v3.2.4            1/1   Running       0   7s    3/3   0.00      0     0         0                    -/-/-

To see which Rest APIs that are available in the running Camel application, you can use camel-jbang as follows:

    $camel get platform-http
