+= Spring Modulith: Event Publication Registry with PostgreSQL
+Rashidi Zin <rashidi@zin.my>
+1.0, August 29, 2026: Initial version
+:toc:
+:icons: font
+:source-highlighter: highlight.js
+:url-quickref: https://github.com/rashidi/spring-boot-tutorials/tree/master/modulith-events
+:source-main: {url-quickref}/src/main/java/zin/rashidi/boot/modulith/events
+:source-test: {url-quickref}/src/test/java/zin/rashidi/boot/modulith/events
+
+In monolithic architectures, ensuring event delivery across module boundaries without tight bean coupling or data loss is essential. In this tutorial, we will explore how to implement resilient, asynchronous event publication using https://spring.io/projects/spring-modulith[Spring Modulith] and its Event Publication Registry backed by PostgreSQL.
+
+== Background
+
+When an application publishes domain events in-memory, failures in asynchronous listeners or unhandled exceptions can result in permanent event loss. The Transactional Outbox pattern solves this by persisting events into the database as part of the primary business transaction.
+
+Spring Modulith provides an out-of-the-box Event Publication Registry that intercepts domain events published within a `@Transactional` boundary and records them in the `event_publication` table. Downstream listeners marked with `@ApplicationModuleListener` consume these events asynchronously and update their completion status in the registry.
+
+== Aggregate & Domain Event
+
+Let's define our shared domain event record in link:{source-main}/common/OrderPlacedEvent.java[`OrderPlacedEvent`]:
+
+[source,java]
+----
+public record OrderPlacedEvent(
+        UUID orderId,
+        String customerEmail,
+        BigDecimal totalAmount,
+        Instant timestamp
+) {
+}
+----
+
+Next, we define our `Order` entity in link:{source-main}/order/Order.java[`Order`]:
+
+[source,java]
+----
+@Table("orders")
+class Order {
+
+    @Id
+    private UUID id;
+
+    private final String customerEmail;
+    private final BigDecimal totalAmount;
+    private OrderStatus status;
+
+    Order(String customerEmail, BigDecimal totalAmount, OrderStatus status) {
+        this.customerEmail = customerEmail;
+        this.totalAmount = totalAmount;
+        this.status = status;
+    }
+
+}
+----
+
+== Event Publishing Service
+
+In link:{source-main}/order/OrderService.java[`OrderService`], we publish `OrderPlacedEvent` within a transactional method:
+
+[source,java]
+----
+@Service
+public class OrderService {
+
+    private final OrderRepository repository;
+    private final ApplicationEventPublisher events;
+
+    public OrderService(OrderRepository repository, ApplicationEventPublisher events) {
+        this.repository = repository;
+        this.events = events;
+    }
+
+    @Transactional
+    public Order placeOrder(String customerEmail, BigDecimal totalAmount) {
+        var order = repository.save(new Order(customerEmail, totalAmount, Order.OrderStatus.CREATED));
+
+        events.publishEvent(new OrderPlacedEvent(
+                order.getId(),
+                order.getCustomerEmail(),
+                order.getTotalAmount(),
+                Instant.now()
+        ));
+
+        return order;
+    }
+
+}
+----
+
+== Asynchronous Listeners
+
+Downstream modules use `@ApplicationModuleListener` to consume the event asynchronously in an independent transaction.
+
+In link:{source-main}/inventory/InventoryListener.java[`InventoryListener`]:
+
+[source,java]
+----
+@Component
+class InventoryListener {
+
+    private static final Logger log = LoggerFactory.getLogger(InventoryListener.class);
+
+    @ApplicationModuleListener
+    void on(OrderPlacedEvent event) {
+        log.info("Reserved inventory for order: {}", event.orderId());
+    }
+
+}
+----
+
+And in link:{source-main}/notification/NotificationListener.java[`NotificationListener`]:
+
+[source,java]
+----
+@Component
+class NotificationListener {
+
+    private static final Logger log = LoggerFactory.getLogger(NotificationListener.class);
+
+    @ApplicationModuleListener
+    void on(OrderPlacedEvent event) {
+        log.info("Sent order confirmation email to: {} for order: {}", event.customerEmail(), event.orderId());
+    }
+
+}
+----
+
+== Verification
+
+We will verify both architectural compliance and event publication behavior using `@Testcontainers` and PostgreSQL.
+
+=== Architectural Boundaries
+
+In link:{source-test}/ModulithEventsApplicationTests.java[`ModulithEventsApplicationTests`], we verify module boundaries using `ApplicationModules`:
+
+[source,java]
+----
+class ModulithEventsApplicationTests {
+
+    private final ApplicationModules modules = ApplicationModules.of(ModulithEventsApplication.class);
+
+    @Test
+    @DisplayName("Verify modular architecture boundaries and rules")
+    void verifyModularity() {
+        modules.verify();
+    }
+
+    @Test
+    @DisplayName("Generate module documentation")
+    void renderDocumentation() {
+        new Documenter(modules).writeDocumentation();
+    }
+
+}
+----
+
+=== Outbox Event Completion
+
+In link:{source-test}/order/OrderEventPublicationTests.java[`OrderEventPublicationTests`], we verify that publishing an order event automatically registers and completes the outbox publication:
+
+[source,java]
+----
+@Testcontainers
+@SpringBootTest(classes = ModulithEventsApplication.class)
+class OrderEventPublicationTests {
+
+    @Container
+    @ServiceConnection
+    private static final PostgreSQLContainer postgres = new PostgreSQLContainer(DockerImageName.parse("postgres:latest"));
+
+    @Autowired
+    private OrderService orderService;
+
+    @Autowired
+    private EventPublicationRepository publicationRepository;
+
+    @Test
+    @DisplayName("When an order is placed Then domain event is published and completed in the outbox registry")
+    void placeOrder() {
+        var order = orderService.placeOrder("rashidi@zin.my", BigDecimal.valueOf(99.90));
+
+        assertThat(order).isNotNull();
+        assertThat(order.getId()).isNotNull();
+
+        await().atMost(Duration.ofSeconds(5)).untilAsserted(() -> {
+            var incompletePublications = publicationRepository.findIncompletePublications();
+            assertThat(incompletePublications).isEmpty();
+        });
+    }
+
+}
