当更改默认属性文件名时，log4j2不能工作的Spring Boot

Question

spring.profiles.active=dev

logging.config=classpath:log4j2-demo.properties

status=debug
name=PropertiesConfig
#
filters=threshold

filter.threshold.type=ThresholdFilter
filter.threshold.level=debug
#
appenders=console

我的应用程序结构：

src
  main
    java
    resources
       application.properties
       application-dev.properties
       log4j2-demo.properties

pom.xml：

Answer 1

如果您使用Log4J2.13.0，则可以在spring配置中使用配置文件定义Log4J2系统属性。所以您可以：

应用程序-开发.属性

log4j2.configurationFile=log4j2-demo.properties.

Log4J2.13.0还支持将Log4J2配置文件放在Spring Cloud Config中。
