我刚刚设置了一个项目来测试junit jupiter(junit 5(，无论我在xml配置中设置的级别如何，我都会在TRACE级别获得一堆log4j2输出。示例输出如下。如何在解析 xml 之前更改 log4j2 的日志级别？
这是我的 xml 配置：
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="TRACE" packages="com.travisfw">
<Appenders>
<Console name="console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
</Console>
</Appenders>
<Loggers>
<Root level="WARN">
<AppenderRef ref="console" />
</Root>
<Logger level="WARN" name="com.travisfw" additivity="false">
<AppenderRef ref="console" />
</Logger>
</Loggers>
</Configuration>
然后，尽管 WARN 是我设置的唯一级别，但我在 junit 报告中得到了 DEBUG 和 TRACE 输出，从它找到我的 xml 配置的地方开始：

我会省略完整的日志，但它会持续一段时间。
我认为您的问题是您将状态记录器的级别设置为 TRACE：status="TRACE".尝试将其更改为不同的级别 - 也许是 WARN。
