Quarkus 1.8.3.Final
直接调用访问 PanacheRepository 的方法按预期工作,但是当通过 EventBus 调用相同的方法时,调用到达该方法并执行每一行,直到它到达任何存储库调用,然后静默失败/退出而没有任何指示发生了什么。
根据日志,直接调用在 Quarkus 主线程中执行,事件总线调用在 vert.x-eventloop-thread-2 中执行。
还尝试了以下步骤的组合,结果相同:
- 将 EventBus 的消费者端包装到 Mutiny Uni。
- 让消费者退回了大学。
- 使消费者明确阻塞=假(默认)。
- 尝试io.vertx.core.eventbus.EventBus和io.vertx.mutiny.core.eventbus.EventBus实现。
- 将消费者置于相同的服务和不同的服务。
- 在被调用方法上使用 @Transactional 注释。
@ApplicationScoped
public class TestEntityRepository implements PanacheRepository<TestEntity> { }
@Slf4j
@Startup
@Transactional
@ApplicationScoped
public class TestService {
@Inject
TestEntityRepository repository;
@Inject
EventBus eventBus;
public void startUp(@Observes StartupEvent event) {
// Call via the event bus prints the log in listEntities() and silently stops when it reaches the repository call.
eventBus.sendAndForget("test_topic", "eventbus call");
// This prints the log in listEntities() and then lists all the entities in the repository.
listEntities("direct call");
}
@ConsumeEvent("test_topic")
public void listEntities(String testMessage) {
log.info("Printing all entities via: " + testMessage);
repository.findAll().stream().map(TestEntity::toString).forEach(log::info);
}
以下是日志的 EventBus 部分的摘录:
