springboot整合log4g2的问题

 

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

在这里插入图片描述

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

<?xml version="1.0" encoding="UTF-8"?>
<!-- status="OFF",可以去掉,它的含义为是否记录log4j2本身的event信息,默认是OFF -->
<configuration status="off" monitorInterval="60">
