前提安装http://mirror.bit.edu.cn/apache/logging/log4j/2.11.2/apache-log4j-2.11.2-bin.zip
Buildpath 配置add extend jar :   log4j-1.2.17.jar
project/src/下 新建log4j配置文件
安装完成配置完后依然报错Caused by: java.lang.ClassNotFoundException: org.apache.logging.log4j.LogManager
解决：查看原来是有2个含有 org.apache.logging.log4j.LogManager 类的的包导致一个是之前接口httpclent-api-log4j的,一个是上面下载的
删除http-api-log4j问题解决
送上配置log4.jproperties
