How to test the project

When you run the project, you should be able to load the URL http://localhost:8080/, but you shouldn't be able to access http://localhost:8080/api/hello-world.

You can log in by sending a post on http://localhost:8080/login and send there username and password, both set to admin.

curl -XPOST -H "Content-Type: application/json" 'http://localhost:8080/login' -d '{"username":"admin","password":"admin"}'

You should get back something like :

{
"id":1,
"username":"admin",
"jwt":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiaWF0IjoxNDg3NjM3OTg0LCJleHAiOjE0ODc2NDE1ODR9.1jMwROveQeR64baJOPdZV4SdpmKKVRvgPg0wJX9sHnI"
}

Now, when you want to load http://localhost:8080/api/hello-world and you send there Authorization header with jwt token from the previous response, you should be successful :

curl -XGET -H 'Authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiaWF0IjoxNDg3NjM3OTg0LCJleHAiOjE0ODc2NDE1ODR9.1jMwROveQeR64baJOPdZV4SdpmKKVRvgPg0wJX9sHnI' 'http://localhost:8080/api/hello-world'
