Java spring boot.war tomcat应用程序日志不在那里

我正试图将我的webapp日志写入tomcat中/logs目录中的.log文件，但该文件未生成，除spring日志和tomcat日志外，任何日志输出也不会发送到控制台。当我将springboot作为一个jar文件运行并嵌入tomcat时，它会很好地写入日志文件，但一旦我通过webapps文件夹部署到tomcat，应用程序日志就找不到了

SpringBoot 2.1.2

Java1.8

Tomcat 8.5

我试过：

• 在setenv.sh中配置日志记录\u配置
• 多个伐木工人。。logback、javautils等

application.properties：

logging.file=../logs/my-app.log
logging.level.org.springframework=INFO
logging.level.com.bose=DEBUG

log4j.log4j的属性：

log4j.rootLogger=${marge.log.level}, stdout, file

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=marge.log

#when stdout is also specified it will not write to the file

log4j.appender.file.MaxFileSize=1MB
# Keep one backup file
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss,SSS} [%c] [%-5p] %n%m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# stdout uses PatternLayout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{HH:mm:ss,SSS} [%c] [%-5p] %n%m%n

# Print only messages of level DEBUG or above in the package com.bose
log4j.logger.com.app=${log.level}

预期：当我在/webapps中部署我的webapp时，应用程序日志（由log4j生成）应该在/logs目录下的my-app.log中

实际：默认情况下，spring boot使用

logback

作为日志绑定器，因此这里的关键概念是先排除

logback

，然后包括

log4j

例如：

<dependency>

 package com.example;

 import org.apache.logging.log4j.LogManager;

  @SpringBootApplication
  public class Application extends SpringBootServletInitializer {

  private static final Logger LOGGER = LogManager.getLogger(Application.class);

  public static void main(String[] args){
    ApplicationContext ctx = SpringApplication.run(Application.class, args);

    LOGGER.info("Info level log message");
    LOGGER.debug("Debug level log message");
    LOGGER.error("Error level log message");
    }
  }
