如何使用camel-zipkin和camel-rabbitmq跟踪消息

我使用不同的交换和队列实现了不同的微服务，其中内部通信通过camel和rabbitMQ进行。我使用

camel-zipkin

进行跟踪，使用

log4j2

进行日志记录

例：

• Service1将消息发布到RabbitMQ（即Exchange 1->队列1） 其中Service2使用消息
• Service2将消息发布到RabbitMQ（即Exchange 1->队列2） 其中Service3使用消息等

我正在使用Springboot

1.5.12.版本

和Camel

2.21.5版本

，具有以下依赖项（Camel）：

• 驼形弹簧靴起动器
• 骆驼兔起动器
• 驼芯
• 骆驼泉
• 驼色齐普金起子
• 骆驼试验
• 驼峰试验弹簧

我需要两个问题的建议

span id、跟踪id未打印在日志中。我在log4j2.xml中添加了必要的占位符

每当将消息发送到exchange时，都会生成唯一的span id和跟踪id 我的问题是：

是否可以为从服务1到服务N的整个数据遍历使用唯一的traceID

如何将跨度id、跟踪id打印到日志

示例代码：

似乎您想要添加的是日志跨度和日志跟踪相关信息。默认情况下，Camel不会为您执行此操作。查看如何在Camel中启用MDC日志记录。请注意，MDC在线程本地上下文上工作，因此，只有在处理线程上预先设置了MDC时，才会显示信息。关于创建新的跨度或跟踪，请查看何时生成新的ID。为camel-zipkin相关类（如

ZipkinTracer

）启用调试日志可能会揭示一些更深刻的见解。实际上，每次发布到rabbitmq时，它都在创建新的span和跟踪，我希望避免这种情况。我还想记录span（X-B3-SpanId）和trace（X-B3-TraceId），类似于我们使用springcloudstarterzipkin时的情况。

@Service
public class SmsActivity {

    private static final Logger log = LoggerFactory.getLogger(SmsActivity.class);
