我按照这里的教程Spring Eureka Tutorial创建了一个基本的Eureka注册表jar应用程序。下一步是将日志记录更改为log4j2，以便我可以使用此处Spring log4j2 guide中的指南创建滚动文件。
我遇到的问题是当我运行应用程序时，我没有抛出任何错误，但是
logger.info("Starting Eureka Registry server...");）都不会显示在任何地方，不会显示在日志文件中，也不会显示在控制台日志中。他们只是被记忆中的某个地方吞没了。所以不知何故，spring正在拿起我的log4j2属性文件，但它仍然使用eureka服务器的默认内置日志记录而忽略其他服务器。
Main.java
@EnableEurekaServer
@SpringBootApplication
public class Main {
public static void main(String[] args) {
Logger logger = LogManager.getLogger(Main.class.getSimpleName());
logger.info("Starting Eureka Registry server..."); //Log message disappears
logger.info("Starting Eureka Registry server..."); //Log message disappears
logger.info("Starting Eureka Registry server..."); //Log message disappears
logger.info("Starting Eureka Registry server..."); //Log message disappears
SpringApplication.run(Main.class, args);
}
}
的pom.xml

最后，我得到一个空的eureka.log文件，控制台日志输出看起来是

我怀疑我可能会遗漏某些东西并且我一直在寻找其他解决方案但是在没有运气的2天之后我会尽力寻求帮助。欢迎任何建议或提示。
