通过springboot切换日志框架理解springboot日志原理

可以按照slf4j的日志适配图，进行相关的切换；

1.slf4j+log4j的方式；

<dependency>
  <groupId>org.springframework.bootgroupId>
  <artifactId>spring-boot-starter-webartifactId>
  <exclusions>
    <exclusion>
      <artifactId>logback-classicartifactId>
      <groupId>ch.qos.logbackgroupId>
    exclusion>
    <exclusion>
      <artifactId>log4j-over-slf4jartifactId>
      <groupId>org.slf4jgroupId>
    exclusion>
  exclusions>
dependency>

<dependency>
  <groupId>org.slf4jgroupId>
  <artifactId>slf4j-log4j12artifactId>
dependency>

需要导入log4j配置文件

2.切换为log4j2

   <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
            <exclusions>
                <exclusion>
                    <artifactId>spring-boot-starter-loggingartifactId>
                    <groupId>org.springframework.bootgroupId>
                exclusion>
            exclusions>
        dependency>

<dependency>
  <groupId>org.springframework.bootgroupId>
  <artifactId>spring-boot-starter-log4j2artifactId>
