== Spring Boot REST DSL / JPA Example

=== Introduction

This example demonstrates how to use JPA and Spring Data along with
Camel’s REST DSL to expose a RESTful API that performs CRUD operations
on a database.

It generates orders for books referenced in database at a regular pace.
Orders are processed asynchronously by another Camel route. Books
available in database as well as the status of the generated orders can
be retrieved via the REST API.

It relies on Swagger to expose the API documentation of the REST
service.

=== Build

You can build this example using:

[source,sh]
----
$ mvn package
----

=== Run

You can run this example with Maven using:

[source,sh]
----
$ mvn spring-boot:run -Dspring.profiles.active=dev
----

Alternatively, you can also run this example using the executable JAR:

[source,sh]
----
$ java -jar -Dspring.profiles.active=dev target/camel-example-spring-boot-rest-jpa-${project.version}.jar
----

This uses an embedded in-memory HSQLDB database. You can use the default
Spring Boot profile in case you have a MySQL server available for you to
test.

When the Camel application runs, you should see the following messages
being logged to the console, e.g.:

....

You can then access the REST API directly from your Web browser, e.g.:

* http://localhost:8080/camel-rest-jpa/books
* http://localhost:8080/camel-rest-jpa/books/order/1

The Camel application can be stopped pressing ctrl+c in the shell.

=== Swagger API

The example provides API documentation of the service using Swagger
using the _context-path_ `+camel-rest-jpa/api-doc+`. You can access the
API documentation from your Web browser at
http://localhost:8080/camel-rest-jpa/api-doc.
