log4j:WARN Please initialize the log4j system properly解决办法

使用log4j，报警如下：

log4j:WARN No appenders could be found for logger

log4j:WARN Please initialize the log4j system properly.

maven项目，在项目下建source folder “/src/test/resources”；

在上面路径下建一个文件log4j.properties；

将如下内容复制到log4j.properties

# For Testing Guys
# Set root logger level to error
log4j.rootLogger=INFO, Console
