FinTech Examples

Example FinTech application provide in this sub module.

fintech-api

Contains an example-api, how calls from the fintech-ui to the fintech-server may look. The example-api is an open-api file to be found in

fintech-api/src/main/resources/static

From this files the server stubs are generated to the target/generated-sources/open-api/src/main/java folder.

fintech-impl

Contains an example implementation of the api. Here the REST calls coming from the Fintech-UI are handled. For that the TPPServers API is called. The imiplementation contains the Controllers to handle the Rest Calls and the Client Stubs, to call the TPPServer. To generate the client Stubs spring-feign is used.

fintech server

The server simply packs the impl to an application.

To view the API:

> mvn clean install
> cd fintech-server
> mvn spring-boot:run

then http://localhost:8086

The application tries to connect to TppServer on port 18080. This is configured in

open-banking-gateway/fintech-examples/fintech-server/src/main/resources/application.yml

First call to FintechServer is always post request /v1/login

When credentials are sufficiant, two cookies will be returned. A sessionCookie with name SESSION-COOKIE and an CORS Cookie with name XSRF-TOKEN. The second cookies value has to be passed from the client with every succeeding call in a header field called X-XSRF-TOKEN. Otherwise all other calls will fail with ttpStatus.Unauthorized.

For the Cookies returned by the fintechServer to the client, all attributes can be set in the application.yml file.

server:
  port: 8086
  controller:
     cookie:
        secure: false
        maxAge: 300
        httpOnly: false
        path: /
        sameSite: none
tpp:
    url: http://localhost:18085

fintech-ui

To serve a dev server:

> cd fintech-ui
> npm install
> npm run start

then http://localhost:4200

The app will automatically reload if you change any of the source files.
