Tracer.addSpanLifecycleListener介绍

[英]Adds the given listener to the #spanLifecycleListeners list using java.util.List#add(Object). This method will do nothing if you pass in null.

WARNING: It's important that any SpanLifecycleListener you add is extremely lightweight or you risk distributed tracing becoming a major bottleneck for high throughput services. If any expensive work needs to be done in a SpanLifecycleListener then it should be done asynchronously on a thread or threadpool separate from the application worker threads.
[中]使用java将给定的侦听器添加到#spanLifecycleListeners列表中。util。列表#添加（对象）。如果传入null，此方法将不起任何作用。
警告：添加的任何SpanLifecycleListener都必须非常轻量级，否则分布式跟踪可能会成为高吞吐量服务的主要瓶颈。如果需要在SpanLifecycleListener中完成任何昂贵的工作，那么应该在与应用程序工作线程分离的线程或线程池中异步完成。
