如何为Google云应用程序引擎提供额外的JDBC属性

Question

我正试图在Google App Engine上从Quarkus连接到PostgreSQL数据库。为此，必须提供额外的JDBC属性“socketFactory”和“cloudSqlInstance”。但我不知道如何在应用程序中指定这些。属性。

根据https://quarkus.io/guides/datasource，有一个属性quarkus.datasource.jdbc.additional。但是如果我尝试使用它，连接会失败，并且在日志中我看到：

提供了无法识别的配置密钥“quarkus.datasource.jdbc.additional jdbc properties”；它将被忽略；

我很确定已经安装了所需的扩展。

我尝试了其他几个属性，如这里提到的“quarkus.datasource.additional jdbc properties”，但没有成功。现在我已经没有办法尝试什么了。有没有办法指定所需的属性？

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

Answer 1

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来连接来自GAE的CloudSQL。
