springboot eureka log4j2空日志文件

Question

我按照这里的教程SpringEureka教程创建了一个基本的Eureka注册表jar应用程序。下一步是将日志记录更改为log4j2，这样我就可以使用Spring log4j2指南中的指南获得一个滚动文件。

我遇到的问题是，当我运行应用程序时，没有抛出错误，但是

1. eureka服务器日志仍会输出到控制台
2. 已创建自定义日志输出文件“eureka.log”，但该文件为空
3. 我编写的任何自定义日志，例如logger。信息（“正在启动Eureka注册表服务器…”） 不会显示在任何位置，不会显示在日志文件或控制台日志中。它们只是在记忆中的某个地方被吞没了

因此，spring以某种方式获取了我的log4j2属性文件，但它仍然使用eureka服务器的默认内置日志记录，而忽略了其他日志记录。

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);     
 }
}

log4j2.properties

status = error
name = PropertiesConfig
property.filename = logs

filters = threshold

filter.threshold.type = ThresholdFilter
filter.threshold.level = info

appenders = rolling
appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${filename}/eureka.log
appender.rolling.filePattern = eureka-%d{MM-dd-yy-HH-mm-ss}-%i.log
appender.rolling.layout.type = PatternLayout

appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=10MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 20

loggers = rolling

#Make sure to change the package structure as per your application
logger.rolling.name = com.lab.servers
logger.rolling.level = debug
logger.rolling.additivity = false
logger.rolling.appenderRef.rolling.ref = RollingFile

最后，我得到了一张空的尤里卡。日志文件和控制台日志输出如下所示

我怀疑我可能遗漏了什么，我一直在寻找其他解决方案，但在两天没有运气之后，我想最好还是寻求帮助。欢迎提供任何建议。
