Springboot微服务集成Nacos，打jar包后运行出现如下问题：

很明显是编码不对，这是因为从Nacos配置中心获取的配置文件有中文，并且运行时没有设置编码格式。

解决办法：运行命令由：

java -jar xxxxx.jar  

改为：

java -Dfile.encoding=utf-8 -jar xxxxx.jar

注：windows平台需要使用''符号包裹参数，否则会有如下异常

错误: 找不到或无法加载主类 .encoding=utf-8

正确命令如下：

java  -D'file.encoding=utf-8' -D'server.port=10001' -jar .\xxxxxx.jar
