Logger.trace介绍

[英]Logs a TRACE message.

TRACE messages must be valuable for diagnosing production problems. They must not be used for development debugging. They can significantly slow down performances. The standard use-case is logging of SQL and Elasticsearch requests.
[中]记录跟踪消息。
跟踪消息对于诊断生产问题必须很有价值。它们不能用于开发调试。它们可以显著降低性能。标准用例是记录SQL和Elasticsearch请求。
