问题描述
在运行java程序时，如果没有设置好log4j的配置，则会碰得到下列warning消息log4j:WARN No appenders could be found for logger (xxx.yyy.zzz).
log4j:WARN Please initialize the log4j system properly.
解决办法
这个一般都是jvm无法找log4j的配置，一个办法是吧log4j.properties复制到jvm的classpath，还有就是在jvm启动时加入参数如：-Dlog4j.configuration=file:///D:/project/config/log4j.properties，这样启动的时候就没有这个warning消息了，另外要注意类库是否正确配置。
