1、坑,pom.xml
哪種啟動方式
web啟動這種方式,不需要去掉引用,
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.8.2</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.25</version>
</dependency>

2、坑,版本衝突,版本不支援
1.3.8以後的spring boot版本對log4j不支援
3、log4j.xml不載入
可以在application.properties檔案中指定: logging.config=classpath:log4j2.xml ;
log4j.xml
