springboot + eureka + log4j2空日誌文件

我按照這裏的教程Spring Eureka Tutorial創建了一個基本的Eureka註冊表jar應用程序。下一步是將日誌記錄更改爲log4j2，這樣我可以使用在此處找到的指南Spring log4j2 guide來製作滾動文件。springboot + eureka + log4j2空日誌文件

我的問題是，當我運行應用程序，我沒有拋出錯誤，但

尤里卡服務器日誌仍然輸出到控制檯
自定義日誌輸出文件「eureka.log」被創建，但它是空的。
我寫的任何自定義日誌，例如logger.info("Starting Eureka Registry server...");都不會顯示在任何地方，不在日誌文件或控制檯日誌中。他們只是在記憶中的某個地方被吞噬。

因此，不知何故，春天正在拿起我的log4j2屬性文件，但它仍然使用默認的內置日誌記錄爲尤里卡服務器和忽略其他。

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);  
} 
}

property.filename = logs 

filters = threshold 

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

appenders = rolling 
appender.rolling.type = RollingFile 
appender.rolling.name = RollingFile

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

最後，我得到一個空eureka.log文件和控制檯日誌輸出看起來這

我懷疑我可能失去了一些東西，我一直在尋找其他的解決方案，但後2天，沒有運氣我想最好問求助。任何建議或提示，歡迎。

在application.properties，您可以指定：

logging.path
logging.file
logging.level

是的，但是這仍然會使用默認的logback爲日誌。我想像教程中那樣將它切換到Log4j2。但它不工作。 – Rhycce
