找到了 ！！您现在可以通过3个简单的步骤在App的Log4j日志文件中查看嵌入式Tomcat的内部日志：
1]加入你的pom：
2]为你的运行arg添加一个新的JVM参数，例如：
3]添加到您的application.properties：
享受生活！ :)
Explaination: 问题是因为Log4j日志级别没有传播到JUL（这是嵌入式tomcat使用的实际日志记录方式）所以上面实现了与JUL和Log4j日志级别的这种连接 .
Reference: 在阅读了Spring boot 1.5.10发行说明（解决方案不需要）后，我看到了新的文档，阐明了如何实现它并解释它：
https://github.com/spring-projects/spring-boot/issues/2923#issuecomment-358451260
我挣扎了很多，并没有发现任何我的帮助 . 我刚从Spring启动应用程序中构建了“WAR” . 将它部署到tomcat实例并按照以下步骤操作，将所有内部tomcat日志（JULI）日志重定向到我的应用程序日志文件
删除现有的JULI库（CATALINA_HOME / bin / tomcat-juli.jar文件）和现有的Tomcat Java Logging配置文件（CATALINA_HOME / conf / logging.properties） .
从Tomcat下载'Extras部分（http://tomcat.apache.org/download-70.cgi）下载JULI Log4j Tomcat库（tomcat-juli.jar） . 将下载的文件放在CATALINA_HOME / bin目录中 .
从Tomcat下载'Extras部分'下载Tomcat JULI适配器库（tomcat-juli-adapters.jar） . 将此文件放在CATALINA_HOME / lib目录中 .
下载Log4j（版本1.2或更高版本），并将下载的库文件放入CATALINA_HOME / lib目录 .
在以下位置创建Log4j配置文件：CATALINA_HOME / lib / log4j.properties . 检查下面的log4j配置是否与默认的Java Logging配置相匹配 .
重启Tomcat .
Log4j配置文件匹配默认Tomcat日志记录设置：
You can also check a adapter avaiable on GIT @ link
在Spring启动应用程序中，您可以进行更改，例如添加和删除嵌入式Tomcat服务器中的jar文件夹，甚至可以使用 TomcatEmbeddedServletContainerFactory.class spring 启动向其添加自定义配置文件 .
请参阅此url，其中包含常见的应用程序属性，其中还包括应用程序日志记录属性和tomcat级别日志记录属性 . 无论您使用yaml还是属性文件，spring boot都使用此配置来引导应用程序 . 搜索以下配置项 .
为Java Util Logging，Log4J，Log4J2和Logback提供了默认配置 . 在每种情况下， Logger 都预先配置为使用控制台输出，并且还提供可选的文件输出
请参考此链接：https://stackoverflow.com/questions/31939849/spring-boot-default-log-location/31939886
spring boot中的嵌入式tomcat在内部将日志回显给控制台 . 默认日志配置将在写入时将消息回显给控制台 . 因此，在您按照描述明确指定文件之前，它将保留在控制台中 .
来自spring boot logging doc .
您可以根据需要保留日志记录 .
嵌入式tomcat的包是
org.springframework.boot.context.embedded.tomcat所以将它添加到您的application.properties文件中
