我正在使用log4j2 kafka附加程序,log4j2.xml看起来像

当我使用Spring Boot和Spring Cloud开发微服务时,我想从配置服务器中读取kafka连接的详细信息。我该怎么办?
答案 0 :(得分:1)
据我所知,您可以在Log4J配置中使用系统属性:${sys:some.property}
:https://logging.apache.org/log4j/2.x/manual/configuration.html#PropertySubstitution
我认为在引导上下文中,从配置服务器读取属性后,您可以将Kafka连接的属性公开到系统属性中,并且可用于下游日志记录配置:https://github.com/spring-cloud/spring-cloud-commons/blob/master/docs/src/main/asciidoc/spring-cloud-commons.adoc#the-bootstrap-application-context
