在Windows上部署项目时遇到一个问题，使用java-jar命令启动应用无法读取Nacos配置，导致报错。问题可能由JVM默认编码（可能是操作系统默认编码）引起，解决方案是在启动时添加-Dfile.encoding=UTF-8参数，确保JVM使用UTF-8编码，从而正确处理配置信息。

今天部署windows上的项目时遇到了个问题：在IDEA中能正常启动，但是只要用java -jar就没法读取nacos配置。

报错信息如下：总之就是读取不到nacos中的配置

解决方式：启动时使用：java -jar -Dfile.encoding=UTF-8 ****.jar

原因：可能是由于当您运行 java -jar 命令时，JVM使用了不同的默认编码（默认情况下是操作系统默认编码）。这可能会导致应用程序无法正确地读取和处理配置信息等内容。

添加 -Dfile.encoding=UTF-8 参数是一种常见的解决方法，因为它将强制JVM使用UTF-8编码。这确保了应用程序可以正确地读取和处理文本数据。
