java - Spring boot 和 GCP - 使用 spring-cloud-gcp-starter-sql-postgresql 连接 Cloud SQL 实例尝试 SSL 并且延迟启动

Question

我有一个 Spring boot 项目，它应该与 Cloud SQL 的实例连接，spring-cloud-gcp-starter-sql-postgresql以避免在项目中显式使用 IP。

到目前为止，它连接良好，但延迟了很多（大约 30 秒开始），因为它尝试通过 SSL 套接字连接，经过多次尝试，它连接了。

在日志中有一行说：

2020-02-19 00:10:09.809  INFO 6779 --- [           main] o.s.c.g.a.s.GcpCloudSqlAutoConfiguration : Default POSTGRESQL JdbcUrl provider. Connecting to jdbc:postgresql://google/test?socketFactory=com.google.cloud.sql.postgres.SocketFactory&cloudSqlInstance=XXXXXX:us-central1:test&useSSL=false with driver org.postgresql.Driver

据我所知，该参数useSSL=false不适用于 postgresql。正确的是，ssl=false但是当我尝试用 application.yml 覆盖 JDBC Url 时，它会打印以下日志：

2020-02-19 00:10:09.816  WARN 6779 --- [           main] o.s.c.g.a.s.GcpCloudSqlAutoConfiguration : Ignoring provided spring.datasource.url. Overwriting it based on the spring.cloud.gcp.sql.instance-connection-name.

我怀疑延迟是因为 SSL 连接。所以我有两个问题：

如何避免使用 SSL 连接？由于我没有明确设置 JDBC URL，因此无法ssl=false在参数中使用。
我怀疑这是因为未设置 SSL 客户端证书而延迟。如果是这种情况，我该如何设置？我已经有了 .pem 但我不知道如何实现它

我添加了我application.yml的配置和提到的日志：

应用程序.yml

spring:
  cloud:
    gcp:
      project-id: xxxxxxx
      config
      sql:

        database-name: test

您可以通过多种方式连接到 Cloud SQL ，在您的情况下，您应该使用 sockect

<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>postgres-socket-factory</artifactId>
    <version>1.0.15</version>
</dependency>

spring.datasource.url: jdbc:postgresql://google/cloudSqlInstance=${instance}&socketFactory=com.google.cloud.sql.postgres.SocketFactory

另一种方法是使用 cloud_sql_proxy （更简洁，我会指出您是否在 GKE 上使用）喜欢：

wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.amd64 -O cloud_sql_proxy

chmod +x cloud_sql_proxy

create a proxy user :
gcloud iam service-accounts create proxy-user --display-name "proxy-account-user"

gcloud projects add-iam-policy-binding [PROJECT_ID] --member \
serviceAccount:[SERVICE_ACCOUNT_EMAIL] --role roles/cloudsql.client

gcloud iam service-accounts keys create key.json --iam-account [SERVICE_ACCOUNT_EMAIL]

./cloud_sql_proxy -instances=[INSTANCE_CONNECTION_NAME]=tcp:5432 -credential_file=key.json &
