spring - 如何使用 SSL 和 Spring Boot 连接到 PostgresQL？

问题描述

如何使用 Spring Boot 连接到 Cloud SQL Postgres (SSL)？

这是我到目前为止的配置：

应用程序属性

spring.datasource.url=jdbc:postgresql://<ip>/<database>?
    ssl=true&
    sslmode=verify-ca&
    sslcert=certs/postgres/client-cert.pem&
    sslkey=certs/postgres/client-key.pem&
    sslrootcert=server-ca.pem

src/main/resources/certs/postgres

- client-cert.pem
- client-key.pem
- server-ca.pem

这是我得到的堆栈跟踪。在我看来不是很有帮助，但也许我错过了一些东西。

解决方案

最后，我连接到 CloudSQL 的方式是使用包org.springframework.cloud:spring-cloud-gcp-starter-sql-postgresql:1.1.1.RELEASE并指定以下属性：

spring.cloud.gcp.sql.enabled=true
spring.cloud.gcp.sql.database-name=<YOUR_DATABASE_NAME>
spring.cloud.gcp.sql.instance-connection-name=<CLOUD_SQL_CONNECTION_STRING>
spring.cloud.gcp.sql.credentials.encoded-key=<BASE_64_ENCODED_SERVICE_ACCOUNT_JSON_FILE>

spring.datasource.username=<YOUR_DB_USERNAME>
spring.datasource.password=<YOUR_DB_PASSWORD>

请记住在测试中设置spring.cloud.gcp.sql.enabled为false。
