NACOS MalformedInputException 無法讀取中文配置問題

1. 問題描述

在windows平台中打包運行springboot jar包提示如下錯誤

• 在idea中運行正常

2. 處理方式

在nacos中刪除中文也可以處理此問題，但不是最佳方案。
在idea中啟動項目時，因為 idea相關配置中設置UTF-8的文件編碼格式file.encoding=utf-8。打包運行后，該設置需要手動指定，如下

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

• 注意其中JVM參數需要放在-jar命令前
• windows平台需要使用''符號包裹參數，否則會有如下異常

錯誤: 找不到或無法加載主類 .encoding=utf-8
