我正在尝试从谷歌应用引擎上的Quarkus连接到PostgreSQL数据库。为此，附加JDBC属性"；socketFactory"；以及"；cloudSqlInstance"；必须提供。但我不知道如何在application.properties中指定这些
根据https://quarkus.io/guides/datasource，有一个propery"；quarkus.datasource.jdbc.附加jdbc属性"。但如果我尝试使用它，连接失败，在日志中我看到：
无法识别的配置密钥"quarkus.datasource.jdbc.附加jdbc属性"提供；它将被忽略；
我确信已经安装了所需的扩展。
我尝试了其他几个属性，比如"；quarkus.datasource.附加jdbc属性"这里提到了，但没有成功。现在我想不出该尝试什么了。有什么方法可以指定所需的属性吗？
application.properties:
quarkus.package.type=uber-jar
# datasource configuration
quarkus.datasource.db-kind = postgresql
quarkus.datasource.jdbc.url = jdbc:postgresql:///counter
quarkus.datasource.username = postgres
quarkus.datasource.password = <password>
quarkus.datasource.jdbc.additional-jdbc-properties=socketFactory=com.google.cloud.sql.postgres.SocketFactory,cloudSqlInstance=<project>:<region>:<instance>
quarkus.datasource.jdbc.max-size=16
# drop and create the database at startup (use `update` to only update the schema)
quarkus.hibernate-orm.database.generation=drop-and-create

试试这个：
quarkus.datasource.jdbc.additional-jdbc-properties.socketFactory=com.google.cloud.sql.postgres.SocketFactory
quarkus.datasource.jdbc.additional-jdbc-properties.socketFactoryArg=<project>:<region>:<instance>
PS：您不需要严格使用SocketFactory来从GAE连接到CloudSQL。
