篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了cmd窗口下执行jar包 logger.info输出乱码，out语句输出正常解决办法相关的知识，希望对你有一定的参考价值。
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
Active code page: 65001
E:\\huadian-project\\fan_intelligent_server\\target>java -jar -Dfile.encoding=utf-8 fanintelligent.jar

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:
总结：之前项目遇到乱码，就是按照上面步骤进行了解决。
