我正在尝试使用 spring cloud gcp 在 Google App Engine 上部署 spring boot 应用程序。

在本地运行 Mysql 时形成 JDBL Url，成功连接到 Google Cloud Platform 中的 Cloud Mysql 数据库。当应用程序被部署（appengine：deploy）时，当api被命中时，它会尝试连接到mysql，形成的url是我的jdbc驱动程序不可接受的。引发以下异常

java.lang.RuntimeException：驱动程序 com.mysql.cj.jdbc.Driver 声称在 org.eclipse.jetty 不接受 jdbcUrl、jdbc:google:mysql://pocketpharmaapi123:asia-southeast1:pocketpharmapi-db-instance/pocketpharmadb。 annotations.ServletContainerInitializersStarter.doStart (ServletContainerInitializersStarter.java:68) 在 org.eclipse.jetty.util.component.AbstractLifeCycle.start (AbstractLifeCycle.java:68) 在 org.eclipse.jetty.servlet.ServletContextHandler.startContext (ServletContextHandler.java: 330) 在 org.eclipse.jetty.webapp.WebAppContext.startWebapp (WebAppContext.java:1406) 在 com.google.apphosting.runtime.jetty9.AppEngineWebAppContext.startWebapp (AppEngineWebAppContext.java:175)

应用部署时如何成功连接数据库？

我试图在 application.properties 中对 jdbcUrl 进行硬编码。它给出了代理例外。

spring.datasource.url=jdbc:mysql://google/pocketpharmadb?socketFactory=com.google.cloud.sql.mysql.SocketFactory&cloudSqlInstance=pocketpharmaapi123:asia-southeast1:pocketpharmapi-db-instance&useSSL=false
