因为项目 spring boot 默认 使用 logback ，但是我这里 指定了 log4j2
org.springframework.boot spring-boot-starter-log4j2
解决办法
只需要 对因此的 spring boot starter 对应依赖排除对应的 log 依赖即可
org.springframework.boot
spring-boot-starter-actuator
org.springframework.boot
spring-boot-starter-logging
org.springframework.cloud
spring-cloud-starter-gateway
org.springframework.boot
spring-boot-starter-logging
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-logging
