依赖版本：
这是云 gcp 的父依赖项，它定义了 spring-cloud-gcp-starter-sql-mysql 依赖项的版本。在我自己的电脑上开发时，我连接到我电脑上安装的 MySql，我没有 spring-cloud-gcp-dependencies 和 spring-cloud-gcp-starter-sql-mysql，只有 mysql-connector-java，一切都运行良好。

这是针对 spring 启动启动器依赖项
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.4.RELEASE</version>
我能够使用此命令从我的云 VM SSH 成功连接到 mysql
mysql --host=34.107.103.23 --user=teamplanner --password 然后它提示我输入密码，我输入 xxxxxxxxx 并连接。
错误必须在 application.properties class 中。改成这样。
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.datasource.url=jdbc:mysql://34.107.103.23/teamplanner?useSSL=false
spring.datasource.username=teamplanner
spring.datasource.password=**********
这一定是工作。这里发生的是你在数据库 URL 前面使用本地 MySQL 服务器端口号。无需将端口号添加为 8080。如果显示错误，因为 8080 已被使用，则只需添加另一个端口号。否则默认情况下它采用端口 8080。

在我的电脑上，当我从 spring initializr 创建项目时，我必须用大写的 R 手动创建 Resources 文件夹。几个月来我一直在 运行 来自 IDE 的项目在 windows 上没有问题。当我将项目移动到计算引擎并使用 mvn spring-boot:run 启动 运行 时，应用程序没有从 Resources 文件夹中读取任何内容，因为它没有按照约定命名，因为它应该是 "resources" 没有大写字母 R . IDE 一定做了一些事情，以便应用程序可以从大写文件夹中读取。重命名文件夹解决了问题。
我在使用 PostgreSQL spring 引导程序时看到了同样的问题，但版本稍新。我正在使用 spring-cloud-gcp 依赖项的 2.0.5 版和 spring boot.
的 2.5.5 版
奇怪的是，我想我注意到属性文件本身的属性顺序对于初学者来说实际上可能是个问题。如果我的属性文件如下所示：
spring.datasource.username=postgres
spring.datasource.password=${sm://projects/212050278585/secrets/postgres-user/versions/1}

spring.application.name=data-svc

然后我在堆栈跟踪中收到错误：

但是如果我将属性重新排序为如下所示：

spring.cloud.gcp.sql.instance-connection-name=ascendant-pixel-331021:us-central1:gcp-poc
spring.datasource.username=postgres
spring.datasource.password=${sm://projects/212050278585/secrets/postgres-user/versions/1}
#name the application
spring.application.name=data-svc
区别在于我的 spring.cloud.gcp.sql.* 属性首先出现在文件中。我知道这很奇怪，但对我来说似乎有所不同。

但是如果我将属性重新排序为如下所示：
spring.cloud.gcp.sql.database-name=service-db
spring.cloud.gcp.sql.instance-connection-name=ascendant-pixel-331021:us-central1:gcp-poc
spring.datasource.username=postgres
spring.datasource.password=${sm://projects/212050278585/secrets/postgres-user/versions/1}
#name the application
spring.application.name=data-svc
区别在于我的 spring.cloud.gcp.sql.* 属性首先出现在文件中。我知道这很奇怪，但对我来说似乎有所不同。
