如何禁用com.spotify.docker- log4j的http-api调试日志

Question

在Java8中使用log4j 1.2.17和com.spotify.docker-client 6.1.1。如果我在DEBUG中设置log4j根日志级别，那么docker客户端http-API会在日志中写入许多消息，例如

09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:113 - http-outgoing-13 << HTTP/1.1 200 OK
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Api-Version: 1.37
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Docker-Experimental: false
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Ostype: linux
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Server: Docker/18.03.1-ce (linux)
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Date: Thu, 04 Oct 2018 06:42:50 GMT
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Content-Type: text/plain; charset=utf-8
09:42:50,624 DEBUG jersey-client-async-executor-0 headers:onResponseReceived:116 - http-outgoing-13 << Transfer-Encoding: chunked

我不知道怎么禁用它。我所有的尝试：

log4j.rootLogger=DEBUG, stdout
log4j.logger.jersey-client-async-executor-0=INFO
log4j.logger.com.sun.jersey=INFO
log4j.logger.com.spotify=INFO

但这并不能阻止它。如何禁用jersey-client-async-executor-0的DEBUG-loggin？谢谢。

Answer 1

您将日志级别设置为Debug ，然后登录到记录器jersey-client，因此也将其设置为Debug。

要么将rootlogger设置为不同的级别，要么不要将jersey-client添加到记录器中。

Answer 2

在log4j中，所有用户定义的记录器都继承自其父记录器，并且所有记录器都是rootLogger.的直接或间接子记录器

为了停止记录器从父级继承，将以下代码添加到您的代码中：

log4j.additivity.jersey-client-async-executor-0=false

这将允许您为该特定组件定义您想要的任何日志级别，并且只允许您定义一个级别。所以你需要做的就是：

log4j.rootLogger=DEBUG, stdout
log4j.logger.jersey-client-async-executor-0=INFO, stdout
log4j.additivity.jersey-client-async-executor-0=false

注您还可以为您定义的每个记录器设置不同的附加器。
