log4j2配置的documentation提供了一个与默认配置等效的简单示例XML文档:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<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="error">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
等效文件看起来像(有效)YAML?
答案 0 :(得分:56)
❐ YAML文件
等效的YAML文件( log4j2.yaml
)如下所示:
Configuration:
status: warn
Appenders:
Console:
name: Console
target: SYSTEM_OUT
PatternLayout:
Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
Loggers:
Root:
level: error
AppenderRef:
ref: Console
此文件会自动加载(假设文件位于类路径中且具有所需的依赖关系),如Automatic Configuration中所述。
❐ Maven
如果您使用的是Maven,则需要以下依赖项:

<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.1</version>
</dependency>
<dependency>
