# Camel Sports API (JSON in REST services)
2+
3+
This is a demo that shows how to use Apache Camel on Spring Boot to expose a REST service.
4+
5+
It also shows how to use Camel's _REST binding mode_ to automatically convert Java POJOs to JSON in the response. JSON support is provided by the `camel-jackson-starter` dependency.
6+
7+
For more info, check out the accompanying YouTube video and blog post!
8+
9+
- [Video: Adding JSON to my REST API (YouTube)][youtube]
10+
- [Blog: Create a REST service in Apache Camel (tomd.xyz)][blog]
11+
12+
## To run
13+
14+
mvn clean spring-boot:run
15+
16+
And the service will be accessible at:
17+
18+
http://localhost:8080/services/go-sports
19+
20+
## To test
21+
22+
To test with `curl`:
23+
24+
curl -H 'Content-Type: application/json' -X POST --data '{ "name": "Sportsball" }' http://localhost:8080/services/go-sports
25+
26+
If you're using another REST testing tool like Insomnia, just make sure it includes the header `Content-Type: application/json` in the request.
27+
28+
## Changing the URL
29+
30+
If you don't like `/services/` and you want to change the root URL used for all Camel servlet endpoints (e.g. REST services) then edit this line in `application.properties`:
31+
32+
camel.component.servlet.mapping.context-path=/services/*
