1. 問題描述

在windows平臺(tái)中打包運(yùn)行springboot jar包提示如下錯(cuò)誤

• 在idea中運(yùn)行正常

2. 處理方式

在nacos中刪除中文也可以處理此問題，但不是最佳方案床三。
在idea中啟動(dòng)項(xiàng)目時(shí)混弥，因?yàn)?idea相關(guān)配置中設(shè)置UTF-8的文件編碼格式file.encoding=utf-8瘫俊。打包運(yùn)行后，該設(shè)置需要手動(dòng)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(shù)需要放在-jar命令前
• windows平臺(tái)需要使用''符號(hào)包裹參數(shù)匿又，否則會(huì)有如下異常

錯(cuò)誤: 找不到或無法加載主類 .encoding=utf-8
