SpringBoot 默认的日志场景启动器为`spring-boot-starter-logging`，我们可以切换到`spring-boot-start-log4j2`。 <br/> **1. 把`spring-boot-starter-logging`排除并引入`spring-boot-starter-log4j`即可** ```xml <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <artifactId>spring-boot-starter-logging</artifactId> <groupId>org.springframework.boot</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency> </dependencies> ```
