Spring Boot 和 GCP Cloud SQL 连接问题

问题描述 投票：0回答：2

我正在使用部署在 Cloud Run (GCP) 上的 Spring Boot App。该应用程序正在使用 IAM 身份验证通过 Cloud SQL 代理建立数据库连接。

目标是实现 Unix 套接字连接而不是 TCP 来连接 Cloud SQL。 下面是

application.yml
内容：

spring:
    cloud:
        gcp:
            sql:
                jdbc:
                    enabled: false
                database-name: db-name
                enable-iam-auth: true
                instance-connection-name: instance-name
    datasource:
        url: jdbc:postgresql:///db-name?unixSocketPath=/cloudsql/instance-name/.s.PGSQL.5432&socketFactory=com.google.cloud.sql.postgres.SocketFactory&enableIamAuth=true&sslmode=disable&cloudSqlInstance=instance-name
        username: my-username
        password: ""
        type: com.zaxxer.hikari.HikariDataSource
        hikari:
            maximum-pool-size: 10

在日志中部署后，我收到一条信息消息：“通过 unix 套接字连接到 Cloud SQL 实例 [实例名称]...” 这是有道理的，因为 

unixSocketPath
属性是在 JDBC URL 中提供的。

我收到的错误是未提供密码（但我使用的是 IAM 身份验证，因此不需要密码）。这是完整的堆栈跟踪：

有什么办法解决这个问题吗？

附言如果我删除 JDBC URL 并启用 GCP SQL 自动配置，一切正常，但我的想法是使用 unix-socket 连接而不是 TCP。

重新发布我对问题的回复。

如果您使用的是 Cloud SQL JDBC 套接字工厂，则无需使用内置的 Cloud SQL 代理与 Unix 套接字集成。

只需删除 unix 套接字配置就可以了。

如this github中所述，您必须将非空字符串值设置为属性中的密码字段，否则它将在驱动程序级别验证失败。

注意：必须为密码属性设置一个非空字符串值。虽然在使用 IAM 身份验证连接 Cloud SQL 连接器时将忽略此属性，但将其留空将导致驱动程序级别验证失败。
