我的 Dropwizard(版本 1.3.8)应用程序中遇到问题，将 HTTP 请求记录到文件中。我已经按照Dropwizard的文档来配置YAML文件，我的config.yml如下所示：
logging:

问题是HTTP请求像这样记录在控制台中：
192.168.1.5 - - [09/Aug/2020:10:08:05 +0000] "GET /api/orders HTTP/1.1" 200 14094 "-" "Apache-HttpClient/4.5.10 (Java/1.8.0_161)" 710
。我也想将其记录在文件中，但它根本不记录它！我尝试使用注释logFormat，但是每个注释logFormat值都出错。 例如，当我在终端中运行时logFormat: "%h %l %u %t "%r" %>s %b"(我正在使用RMI 参数从远程机器收集 JMX 样本)：
java -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=1616 -Dcom.sun.management.jmxremote.rmi.port=1616 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -jar ./target/DW-Bookshop-1.0-SNAPSHOT.jar server config.yml
。我得到数字格式异常：

我也研究过这个答案，但没有运气！另外，我正在运行Fedora 31 OS，并且使用的是Java 8。
任何建议/帮助将不胜感激。
UPDATE1：
我已经深入研究了配置文档，并在此链接下找到了模式，并在logFormat键下编辑了值，如下所示：
logFormat: "%h %l %u [%t] '%r' %s %b '%i{Referer}' '%i{User-Agent}'"
还发现 Logback 项目使用 PatternLayout 类并在终端中获得了此输出(因为起始行和其他行与往常一样)：

显然，我需要创建logback.xml文件，如以下行所述：
09:27:33,944 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.xml]
知道该 logback.xml 文件需要在 MAven 项目中的位置以及我应该使用logFormat的哪个值吗？
要在文件中记录 http 请求，您必须设置server: requestLog:配置。logging配置用于配置应用程序中的日志。
有关该配置以及回日志访问和回日志访问模式引用的文档，请访问： https://www.dropwizard.io/en/latest/manual/configuration.html#request-log
这是我的例子：
