SpringBoot使用log4j2记录日志 Gradle配置

1、修改build.gradle
然后添加log4j依赖
// log4j2日志框架
implementation 'org.springframework.boot:spring-boot-starter-log4j2'
// 加上这个才能辨认到log4j2.yml文件
implementation 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:2.10.2'

由于springboot本身自带的logback,会导致冲突。所以这块需要排除默认日志。
configurations {
all*.exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
}

2、在application.yml中添加
logging:
config: classpath:config/log4j2.yml
3、新建log4j2.yml文件,放在resources/config目录下,内容如下:
# 共有8个级别,按照从低到高为:ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF。
Configuration:
status: warn
monitorInterval: 30
Properties: # 定义全局变量
Property: # 缺省配置(用于开发环境)。其他环境需要在VM参数中指定,如下:
#测试:-Dlog.level.console=warn -Dlog.level.xjj=trace
#生产:-Dlog.level.console=warn -Dlog.level.xjj=info
