Apache camel Camel EventNotifierSupport生成重复的输出

为了在Camel上执行性能度量和审计日志记录，AuditEventNotifier的实现如下所示。但是，每个事件都记录两次。例如，31140的消息完成事件记录两次。有人能给我一个如何解决这个问题的提示吗

路由定义

AuditEventNotifer实现

下面是制作的日志

---

检查通知程序bean是否未配置两次。如果用

@Component

注释该类，则必须在SpringXML配置中定义bean

---

选择一种或另一种可能性，但不能同时选择两者。

因为您尚未覆盖

public boolean isEnabled(EventObject event)

它为事件的每个状态打印消息

如果您希望消息在发送时只打印一次，请检查下面的代码块

@Component
public class AuditEventNotifer extends EventNotifierSupport {

    private static final Logger LOGGER = LoggerFactory
            .getLogger(AuditEventNotifer.class);

    @Override
    public boolean isEnabled(EventObject event) {
        return event instanceof ExchangeSentEvent;
    }
    @Override
    public void notify(EventObject event) throws Exception {

        LOGGER.info(event.toString());
    }

}

@刘易斯王：我用这个取代了我以前的答案。如果它解决了您的问题，请检查它。
