Spring Boot整合Log4j2.xml的时候返回以下错误:
Caused by: org.apache.logging.log4j.LoggingException: log4j-slf4j-impl cannot be present with log4j-to-slf4j
进行了解决。
Spring Boot整合Log4j2.xml经过以下操作:
log4j2.xmlsrc/main/resources目录下build.gradle中添加:dependencies {
...
implementation "org.springframework.boot:spring-boot-starter-log4j2"
...
}
启动应用,返回以下错误:
Caused by: org.apache.logging.log4j.LoggingException: log4j-slf4j-impl cannot be present with log4j-to-slf4j
解决方法如下:
我们需要将spring-boot-starter-logging这个模块从所有的库中排除。这里我在build.gradle中使用了以下配置:
configurations {
all {
exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
}
}
再次启动应用,问题解决。
