我最近搬到了Spring Boot，并使用了log4j2和Sl4j，它运行得非常好。在使用Feign，hystrix和Spring云库进行了大量更改后，某些时候log4j日志记录被破坏了。我的第一次尝试是删除我添加的那些奇特的春天云库，但不幸的是，这并没有解决这个问题。我在部署和初始化日志记录上下文时看到了一些奇怪的东西。以下是我的追踪。

我从类路径中排除了不必要的日志记录相关库，如commons-logging，jul-to-slf4j，log4j-over-slf4j和logback stuff。
我的类路径中有以下jar文件
我在my-service.json文件中看到的只有以下内容
{
"time" : "2016-12-05T21:22:08.742Z",
"service" : { },
"message" : {
"category" : "org.eclipse.jetty.util.log",
"severity" : "INFO",
"text" : "Logging initialized @2227ms"
},
"v" : "2"
}
有人可以帮我解决这里发生的事吗？我也在控制台中看到了INFO日志。但是appender似乎没有起作用。
