FINT Example Client using Spring
Example web application for creating cascading web APIs using FINT APIs. It uses Spring Framework for OAuth, HTTP, JSON HAL HATEOAS parsing, and web container.
The purpose of this application is to demonstrate how to interact with FINT APIs, and provide some basic ideas of services that can be built.
The properties used for authorization are stored in application.yml,
under the key security.oauth2.client. The configuration is specified by
the @Bean restTemplate in no.fint.labs.Config and autowired into Application.
This is done by a Spring HATEOAS library, enabled by the @EnableHypermediaSupport(type=HAL)
annotation in Application. It also uses the FINT generated model classes from FINTmodels.
To get HATEOAS resources with links, the model class is wrapped in Resources<Resource<?>>.
This is all wrapped in ParameterizedTypeResource<?> to instruct the Spring RestTemplate and Jackson to
deserialize into the correct object.
The Web container has two REST controllers configured, Bursdager and Telefonliste. They serve the following REST endpoints:
/bursdager- Provides a list of people with birthday today/jubilanter- Provides a list of people with an anniversary birthday in the near future/telefonliste- Provides a list of people's mobile phone numbers.
