Flyway 在尝试连接到 GCP SQL 时抛出异常“HikariPool-1 连接不可用”

Question

我的 Spring Boot 应用程序使用 Flyway 进行数据库迁移并连接到 GCP Cloud 中的 Postgres。

它在 JRE 11 上工作，但在我们升级到 JRE 17 后开始崩溃。

日志显示服务启动成功并启动 Hikari 连接，但随后在 Flyway 尝试获取连接时中断。

所以它是这样开始的：

20:57:19.727 [main] INFO com.zaxxer.hikari.HikariDataSource [] - HikariPool-1 - Starting...
20:57:19.920 [main] INFO c.g.cloud.sql.core.CoreSocketFactory [] - First Cloud SQL connection, generating RSA key pair.
20:57:27.227 [main] INFO com.zaxxer.hikari.HikariDataSource [] - HikariPool-1 - Start completed.
20:57:27.420 [main] INFO o.f.c.i.d.base.BaseDatabaseType [] - Database: jdbc:postgresql://google/dbname_dev (PostgreSQL 13.7)
20:57:27.627 [main] INFO o.f.core.internal.command.DbValidate [] - Successfully validated 4 migrations (execution time 00:00.106s)

显示它已建立连接，验证了迁移，但随后显示错误：

WARN  o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext [] - Exception 
encountered during context initialization - cancelling refresh attempt: 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 
'flywayInitializer' defined in class path resource 
[org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: 
Unable to obtain connection from database: HikariPool-1 - Connection is not available, 
request timed out after 30000ms.

HikariPool-1 - Connection is not available, request timed out after 30000ms.

最后：

20:57:57.653 [main] INFO com.zaxxer.hikari.HikariDataSource [] - HikariPool-1 - Shutdown initiated...
20:57:57.656 [main] INFO com.zaxxer.hikari.HikariDataSource [] - HikariPool-1 - Shutdown completed.

问题是由 Flyway 库引起的，因为一旦我禁用

spring.flyway.enabled=false

应用程序就会按预期工作并成功地与数据库一起工作。

这里是 POM 片段：

JRE 11 版本：

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-maven-plugin</artifactId>
    <version>9.7.0</version>
</dependency>

</dependency>
<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>postgres-socket-factory</artifactId>
    <version>1.4.4</version>
</dependency>

JRE 17 版本：

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-maven-plugin</artifactId>
    <version>9.16.1</version>
</dependency>

<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>postgres-socket-factory</artifactId>
    <version>1.11.0</version>
</dependency>

但我试着玩这些版本，我也试着保留旧版本，但它还是坏了。

谢谢
