apache/causeway-app-simpleapp

This system is a Java-based application built on the Apache Causeway framework, serving as a modernized version of the Apache Isis platform. It implements a simple domain model using JPA and Spring Boot, featuring a web interface with REST and GraphQL endpoints. The codebase includes comprehensive test coverage and supports background processing and scheduled jobs.

10 changes.

This period was dominated by the migration of the codebase from Apache Isis to Apache Causeway, including a comprehensive shift from JDO to JPA for data persistence. The work involved renaming the project, updating dependencies, and refactoring domain models and web applications to align with the new framework and Jakarta namespace.

5 changes.

This period focused on refining the domain model by introducing new type annotations and restructuring the SimpleObject layout for better organization. Concurrently, the project upgraded its testing infrastructure by migrating to JUnit 5 and updating integration tests to align with modern Java and Spring Boot standards.

New Java annotations, Name and Notes, have been added to the domain model. These annotations, part of the Apache Causeway framework, define constraints and UI hints for string-based fields. The Name type enforces a maximum length of 40 characters, while the Notes type allows up to 4000 characters and is configured to be hidden in all tables. These changes provide a more structured way to define and display these common string types within the application.

The webapp module has been restructured with a new AppManifest that registers various framework extensions (including JPA, Flyway, and GraphQL) and imports application-specific modules. A new HomePageViewModel is introduced to display a list of SimpleObjects on the home page, supported by a corresponding layout XML. Additionally, a custom REST controller is added to expose simple objects at /custom/simpleObjects, and the application now includes support for Quartz scheduling and H2 console access. The old menubars.layout.xml has been replaced with a more comprehensive menu configuration, and legacy translation files have been removed.

The application module has been removed, along with its associated test infrastructure. This includes the deletion of the \ApplicationModule\ configuration class, the \DomainAppFixtureScriptsSpecificationProvider\, the \DomainAppDemo\ fixture script, and the \HomePageService\ and \HomePageViewModel\ for the home page. Additionally, all related integration tests, BDD specifications, and their corresponding approval files have been deleted, effectively removing the application's core service and test coverage from this module.

The SimpleObject persona fixture was refactored to support attaching PDF files to created objects. The enum now carries a content filename, and the builder script reads the corresponding PDF from the classpath to attach to the SimpleObject. Additionally, the fixture now sets a 'last checked in' date using a fake data service and clock service, and imports were updated from javax to jakarta.

The SimpleObject domain model and SimpleObjects service are now implemented using JPA (Jakarta Persistence) with the Apache Causeway framework, replacing previous JDO-based implementations. This includes the addition of a Quartz-based scheduled job (SampleJob) for background processing, a Spring-managed health check service (HealthCheckServiceImpl) that validates the JPA integration, and a seed service (SeedSecurityService) that runs fixture scripts during prototyping. The changes also update imports from javax to jakarta and integrate with the new Causeway entity listener and JPA support services.

The project has been renamed from Apache Isis to Apache Causeway, reflected in updated documentation, configuration files, and build scripts. Users will now encounter the 'Causeway' branding and terminology throughout the application and its supporting files, including the removal of legacy 'Isis' references and the adoption of new build and run scripts.

The SimpleModule has been migrated from JDO to JPA, introducing JPA-specific annotations such as @EnableJpaRepositories and @EntityScan, and updating the fixture teardown to use JPA-aware classes. The module also imports several Apache Causeway extension modules (PDF.js, FullCalendar, Fake Data, and JPA persistence) and renames the implemented interface from Module to ModuleWithFixtures, reflecting the broader framework rename from Isis to Causeway.

The legacy domain classes SimpleObject and SimpleObjects have been removed from the module-simple module. This eliminates the previous implementation of the simple object model and its associated repository service, likely as part of a broader refactoring or migration of the application's data model.

The \logging-dn-enhance.properties\ file, which configured Log4j for DataNucleus, has been removed. Additionally, the \persistence.xml\ file, which defined the JPA persistence unit named 'simple', has been deleted. These changes reflect a shift away from the previous persistence and logging setup.

The layout for SimpleObject has been simplified and reorganized. The previous layout, which included a 'General' tab with name and notes fields, has been replaced with a new structure featuring 'Identity', 'Other', and 'Metadata' tabs, along with a separate 'Details' fieldset. This change streamlines the user interface by removing redundant or unused sections and consolidating the layout into a more logical grouping of properties.

Adds integration tests for the webapp module; Migrate simple module tests to JUnit 5 and update test infrastructure; Removal of legacy unit and integration test classes.

The SimpleApp starter project has been migrated from the JDO object store to the JPA object store, with the parent POM and all module POMs updated to version 3.6.0. This includes renaming the project artifacts to include a '-jpa' suffix (e.g., 'simpleapp-jpa'), switching dependencies from 'isis' to 'causeway' artifacts, and adding new test modules for the webapp and simple modules. The webapp module now includes support for the GraphQL viewer and additional extensions like Flyway, layout loaders, and security encryption.
