一问题描述

执行jar包，在cmd窗口中执行jar包，看到输出中，logger.info的输出为乱码，而System.out.println()输出为正确的日志。

二解决办法

1.因为cmd默认的编码为GBK，jar包一般设置为UTF-8;

2.在cmd窗口先输入：

2.1 chcp 65001 （注意之间有空格）

2.2 然后执行jar包命令：E:\huadian-project\fan_intelligent_server\target>java -jar -Dfile.encoding=utf-8 fanintelligent.jar

3.如果还是乱码的话，需要修改字体：

在命令行标题栏上点击右键，选择"属性"->"字体"，将字体修改为True Type字体"Lucida Console"，然后点击确定将属性应用到当前窗口。如下图所示:
