一：pom.xml配置：去掉Spring boot 默认的spring-boot-starter-logging，引入spring-boot-starter-log4j2
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency>
二：应用配置application.yaml
# logging logging: config: classpath:log4j2.xml
三：log42j.xml配置

四：Druid配置
