We now support SpEL expressions in routing targets for events to be externalized. Introduced a BrokerRouting.getTarget(Object) overload to allow access to the event object in the SpEL expression. To support those, event externalizers will have to call that method where they previously called ….getTarget().
We now ship our own APT (included in the core starter) that automatically extracts the user code's Javadoc into a metadata file in generated-spring-modulith/javadoc.json. The documentation generation support picks up that file through SpringModulithDocumentationSource. Asciidoctor has been extended to make more use of the Javadoc where ever it renders a plain type.
We now expose ApplicationModuleSourceFactory as Spring Factories-based SPI interface to further contribute ApplicationModuleSource instances either from a provided root package subject for module detection through a (potentially customized) ApplicationModuleDetectionStrategy or by explicitly listing particular module base packages.
We now expose a spring.modulith.events.completion-mode property, defaulting the previous behavior to a value of UPDATE. The property can also be configured to DELETE, which will cause the persistence implementations to flip to removing the database entries for event publications instead of setting the completion date.
The ApplicationModules bootstrap now triggers the module base package detection, followed by a new, additional pass of detecting nested application module packages. Those packages are now added to the ones we create ApplicationModule instances for and also handed into the module instance creation step as exclusions to make sure that parent modules do not include code residing in sub-modules.
The bootstrap of ApplicationModules now uses a dedicated ApplicationModuleSource to allow calculating a default module name relative to the application base package.
Each module now operates on the Classes instance obtained from the JavaPackage instance that constitutes the module's base package but filtered by the given exclusions.
We now expose a configuration property spring.modulith.detection-strategy that can take either of the two prepared values "direct-sub-packages" (default) or "explicitly-annotated", or a fully qualified class name of the strategy to use.
Removed ApplicationModuleStrategies enum to avoid exposing the enum values as additional implementations. Those are now held as inline lambda expression in the factory methods on ApplicationModuleStrategy. Extracted the lookup of the strategy to use into ApplicationModuleDetectionStrategyLookup for easier testability.
When defining allowed application module dependencies to named interfaces, the asterisk can now be used to allow referencing all named interfaces declared by the target module.
The exclusion of types from the Application Modules model is now described in the section about the ApplicationModules type already. That general section is now located before the discussion of simple and advanced modules.
The verification section now mentions the behavior for open modules as well.
Introduce @PackageInfo annotation to allow marking a types as alternative to Java's native package-info.java so that annotation lookups on a JavaPackage will also find annotations placed on that type. Useful to declare package scoped metadata like @ApplicationModule and @NamedInterface for languages that do not support packages well enough (read: Kotlin).
