ddd4j-quarkus Runtime

Overview

Covers CDI/Arc, CommandBus, DomainEventPublisher, SubjectProvider, Context, and startup/shutdown uniformly, not split per artifact. Choose 3.3.x or 4.0.x first, then read the current source.

When to Use

• Producing CommandBus, DomainEventPublisher, or SubjectProvider beans for ddd4j SPIs via CDI producers or BuildItems in a Quarkus application.
• Binding request-scoped Context and restoring it on success, exception, and async completion paths.
• Owning ddd4j resource lifecycle with startup/shutdown observers: drain, reverse-order close, idempotent close.
• Diagnosing duplicate SPI registrations or an Arc unsatisfied dependency build failure for a ddd4j port.
• Aggregating readiness from real dependencies instead of a hardcoded state.
• Reviewing an application's Arc wiring against Quarkus (not Spring) registration semantics on either line.
