要解决"Axon - 使用ListenerInvocationErrorHandler从SagaEventHandler引发的发布事件未正确解析的问题",您可以采取以下步骤:
@Configuration
public class AxonConfig {
@Autowired
public void configure(EventProcessingConfigurer configurer) {
configurer.registerListenerInvocationErrorHandler("myErrorHandler", c -> new MyListenerInvocationErrorHandler());
}
}
public class MyListenerInvocationErrorHandler implements ListenerInvocationErrorHandler {
@Override
public void onError(Exception exception, EventMessage> event, EventListener eventListener, UnitOfWork unitOfWork) throws Exception {
// 处理错误的逻辑,例如记录日志或发送特定的错误消息
System.out.println("Error occurred while invoking event listener: " + eventListener);
exception.printStackTrace();
}
}
@SagaEventHandler(associationProperty = "id")
public void handle(MyEvent event) {
// 模拟处理事件时发生异常
throw new RuntimeException("Error occurred while handling event");
}
@Autowired
private EventGateway eventGateway;
public void publishEvent() {
try {
eventGateway.publish(new MyEvent("123"))
.registerListenerInvocationErrorHandler("myErrorHandler");
} catch (Exception e) {
e.printStackTrace();
}
}
通过以上步骤,您将能够捕获从SagaEventHandler方法中引发的异常,并使用自定义的ListenerInvocationErrorHandler进行处理。您可以根据实际需求来自定义错误处理逻辑。
