This application is a fully JHipster generated demo, demonstrating the usage of JHipster UAA
An UAA is defined as User Account and Authentcation service, and manages user accounts, user authentication and authorization. Instead of share JHipster UAA as an prebuilt application as JHipster Registry or JHipster Console, this UAA is generated as an JHipster application, with options to implement the user account API with all existing features wrapped up in JHipster.
You can find further information in the official JHipster UAA documentation and in my tutorial blog article
- an UAA (as it rolled out from generators)
- app1 and app2 with one entity each, "Foo" on app1 and "Bar" on app2 both with one field "value" of type "string"
- an gateway app, generated using app1 and app2 entity configuration
- a docker directory, storing docker-compose information to start the application using all apps
To start of quickly, first use the build script in root:
$ ./build-all.shand then just start the whole setup using:
$ cd docker/
$ docker-compose up -dYou can use ./gradlew test to test the applications the usual way. For a test using curl or some other HTTP client, you first
$ curl -XPOST -d "grant_type=password" -d "username=admin" -d "password=admin" "web_app:@localhost:8080/uaa/oauth/token"
{"access_token":"eyJ...L2A","expires_in":43199,"scope":"openid","jti":"86f84e4b-e242-43d0-ab30-a759dcc03f19"}
to retrieve authorized "bars":
$ curl -H "Authorization: Bearer eyJ...L2A" "localhost:8080/bar/api/bars"
[]
you can also login as just an internal service using:
$ curl -XPOST -d "grant_type=client_credentials" "internal:internal@localhost:8080/uaa/oauth/token"
{"access_token":"eyJh...FmrQ","token_type":"bearer","expires_in":43199,"scope":"web-app","jti":"7229e92f-824e-4940-9727-48d9df31eeed"}
and perform a similar request to the SomeController endpoint from app1:
$ curl -H "Authorization: Bearer eyJh...FmrQ" "localhost:8080/foo/api/client/bar"
[]
note: it sometimes happens, that the first request fails with code 500 and some Zuul error. Just repeat the operation, then this should work.
