All tutorials focus on the usage of Jexxa. Therefore, the business logic in these tutorials is without any special meaning. Nevertheless, we tried to find typical scenarios of business applications that can be easily mapped to other applications.
In these tutorials we assume that you have a basic understanding of:
-
Writing Java code and build your programs using maven.
-
First experience in the use of a database and message bus.
-
An initial idea of ports and adapters architecture as described here.
-
All tutorials run by default without any additional infrastructure services such as JMS or a database.
-
In case you want to just run the tutorials, you can use:
- Docker images provided here.
- Docker stacks for all tutorials: HelloJexxa, TimeService, BookStore, ContractManagement
-
In case you want to build the tutorials, please ensure a locally running developer stack providing a Postgres database, ActiveMQ broker, and Swagger-UI to access these applications.
