【log4j2配置报错】SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder"

【一.问题描述】

1.日志框架换成log4j2时报错

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See www.slf4j.org/codes.html#… for further details.

2.引入依赖

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.19.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.19.0</version>
</dependency>

【二.解决方法】

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.17.2</version>
</dependency>

可以去maven仓库下载其他版本

central.sonatype.dev/artifact/or…

使用log4j2的话，可以引入log4j-slf4j-impl-2.17.2.jar包，这是log4j对slf4j相关方法的实现
