1.导入jar
springboot默认是用logback的日志框架的，所以需要排除logback，不然会出现jar依赖冲突的报错。

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions><!-- 去掉springboot默认配置 --> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <!-- 引入log4j2依赖 --> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency> |
2.配置文件
1.如果自定义了文件名，需要在application.yml中配置
2.默认名log4j2-spring.xml，就省下了在application.yml中配置
在applicaiton.yaml中添加配置

logging: #日志文件 config: classpath:log4g2.xml level: com.alibaba.nacos.client.config.impl: WARN cn.jay.repository: trace file: #${file.name} 后期可以改成${spring.application.name} path: /log/${file.name} file: name: dome |
在config中配置log4g2.xml文件
