Log4j2找不到使用Spring Boot的日志记录实现 [英] Log4j2 could not find a logging implementation with Spring Boot
本文介绍了Log4j2找不到使用Spring Boot的日志记录实现的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在尝试将log4j2与spring boot结合使用时遇到此错误.
ERROR StatusLogger Log4j2 could not find a logging implementation.
Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
我已遵循此指南: https://logging添加了两个log4j2依赖关系. apache.org/log4j/2.x/maven-artifacts.html
我的依存关系:树看起来像这样:

我已经使用默认配置将标准log4j2.xml文件添加到src/main/resources/config中:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="org.apache.log4j.xml" level="info"/>
<Root level="debug">
<AppenderRef ref="STDOUT"/>
</Root>
</Loggers>
</Configuration>
有没有猜到?我尝试从Spring Tool Suite内运行，并使用maven spring-boot插件.
根据普遍要求，以下是完整的pom.xml:

解决方案
我查找了http://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html#howto-configure-log4j-for-logging - and also added the two log4j2-dependencies from https://logging.apache.org/log4j/2.x/maven-artifacts.html
My dependency:tree looks like this:

I have added the standard log4j2.xml-file to src/main/resources/config with the default config:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="org.apache.log4j.xml" level="info"/>
<Root level="debug">
<AppenderRef ref="STDOUT"/>
</Root>
</Loggers>
</Configuration>
Any guesses? I've tried running from within Spring Tool Suite and with the maven spring-boot plugin.

解决方案
I looked up the source code of LogManager.class and found the reason was there's no LoggerContextFactory found in log4j-provider.properties which should be found in log4j-core.jar/META-INF.
So check your log4j-core.jar/META-INF/log4j-provider.properties file , or you can delete your log4j-core.jar in your local repository.
这篇关于Log4j2找不到使用Spring Boot的日志记录实现的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
