运行StackSaga Admin服务器失败：配置文件缺失问题求助

运行可执行Jar包stacksaga-admin-1.0.0.jar时，Spring应用启动失败，核心原因是系统无法找到stacksaga-admin-application.properties配置文件，完整错误日志如下：

解决方法 #

• 确认配置文件位置
  • 若配置文件为外置文件，确保它与Jar包在同一目录下；或启动时通过参数指定路径：

    java -jar stacksaga-admin-1.0.0.jar --spring.config.location=./stacksaga-admin-application.properties
    

  • 若配置文件是内置在Jar包中，检查项目打包前是否将该文件放在src/main/resources目录（Maven/Gradle项目），重新打包Jar包。
• 核对文件名：确保文件名拼写完全正确，注意Linux/macOS系统区分大小写，Windows系统不区分。
• 指定自定义路径：如果配置文件在其他目录，启动时明确指定绝对路径：

  java -jar stacksaga-admin-1.0.0.jar --spring.config.location=/opt/configs/stacksaga-admin-application.properties
