Java log4j.properties 文件 - 警告在 Eclipse 中找不到记录器的附加程序

log4j.properties file - WARN No appenders could be found for logger at eclipse

提问by nazar_art

I tried to configure log4j with `log4j.properties' file.

我尝试使用“log4j.properties”文件配置 log4j。

All work but but I caught some strange warning:

一切正常，但我发现了一些奇怪的警告：

log4j:WARN No appenders could be found for logger (org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfigfor more info.

log4j:WARN 找不到记录器 (org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager) 的附加程序。log4j:WARN 请正确初始化 log4j 系统。log4j:WARN 有关更多信息，请参阅http://logging.apache.org/log4j/1.2/faq.html#noconfig。

I couldn't figure out what is wrong with this. All should work.

我无法弄清楚这有什么问题。一切都应该工作。

Here is struckture of project:

这是项目的截图：

EDIT:

编辑：

I load log4j.properties from code:

我从代码加载 log4j.properties：

PropertyConfigurator.configure("src/resourses/log4j.properties");
Logger.getRootLogger();

Edit2:

编辑2：

I tried change location log4j.propertiesat different location as src/main/resoursesor src/test/resourses, src/resoursesand changed loading from code.

我尝试将log4j.properties不同位置的位置更改为src/main/resoursesor src/test/resourses，src/resourses并更改了从代码加载。

And always it fails:

而且总是失败：
