第 20 章 Log

初始日志配置从 etc/org.ops4j.pax.logging.cfg 加载。

此文件是 标准 Log4j2 配置文件。

找到不同的 Log4j2 元素：

您可以在 文件中直接添加自己的初始配置。

默认配置如下：

默认配置使用 out 文件 appender 定义 ROOT 日志记录器，其 INFO 日志级别。您可以将日志级别更改为任何 Log4j2 有效值。从最详细到最详细的信息，您可以指定 TRACE, DEBUG, INFO, ERROR, 或 FATAL。

要启用它，您必须在 rootLogger 中添加 stdout 附加程序：

log4j2.rootLogger=INFO, out, stdout, osgi:*

log4j2.appender.jdbc.cs.lazy = true
