Question

我正在将我的Spring Boot应用程序与Google Cloud Sql连接，并通过将凭据文件放置在 src / main / resources 中但未连接问题 >当我尝试运行Jar文件时-[FileNotFound]

:: Spring Boot ::（v2.0.3.RELEASE）

application.properties-

spring.cloud.gcp.credentials.location=classpath:ArpanShoppingApp-863d536d1f93.json

运行中的jar文件出现异常

java -jar CloudSQLConnect-1.0.jar

例外-

Answer 1

这似乎是spring-cloud-gcp的限制。凭证文件似乎必须位于文件系统上，并且不能打包到jar中。最新代码比您使用的M1版本多a better error message。

Spring Boot Project Jar文件不读取放置在类路径上的文件
