带有Slf4的Log4j2以及Spring Boot初始化很好，但不要记录其他任何内容

Question

我最近使用了Spring Boot，并且使用了log4j2和Sl4j，这两者都非常好用。在我使用Feign、hystrix和Spring cloud库进行了大量更改之后，在某个时候log4j日志记录被破坏了。我的第一个尝试是删除我添加的那些别致的spring云库，但不幸的是，这并没有解决这个问题。在部署和初始化日志上下文过程中，我看到了一些奇怪的东西。下面是我的踪迹。

我对取消注册的MBean很好奇。因为我的附加程序未注册。也在这个下面对我来说毫无意义！

我看到的是下面的my-service.json文件

{
 "time" : "2016-12-05T21:22:08.742Z",
 "service" : { },
 "message" : {
   "category" : "org.eclipse.jetty.util.log",
   "severity" : "INFO",
   "text" : "Logging initialized @2227ms"
 },
 "v" : "2"
}

有人能帮我弄清楚这是怎么回事吗？我在控制台中也看到了信息日志。但附录似乎不起作用。

-d选项我使用的是-dlog4j.configurationfile。拉入的一个JAR与Spring Boot配置冲突。使用spring boot的-dlogging.config选项解决了这个问题。
