Google app engine 无法使用Spring Cloud gcp starter将Spring引导与云SQL连接

Spring Boot新手尝试将我的应用程序托管在GCP AppEngine上，并使用第二代云SQL（mysql）

使用我从这里获得的Spring Cloud GCP启动器： ，我正在尝试让我的本地spring boot应用程序连接到云SQL。尝试在本地Tomcat上运行SQLApplication时，我得到：

我尝试将mysql套接字工厂直接添加到pom.xml，但没有成功：

<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>mysql-socket-factory</artifactId>
    <version>1.0.10</version>
</dependency>

com.google.cloud.sql
mysql插座工厂
1.0.10

我已确保我的SQL API已启用。

谢谢大家!

我认为你应该设置一个代理

---

请参见

您不需要设置云SQL代理。 如您所见：

请注意，您无需使用代理或配置SSL即可从App Engine标准或灵活的环境连接到云SQL。这些连接自动使用“内置”代理实现

使用AppEngineJava，可以在幕后进行jdbc连接，而无需任何IP地址，只需实例名称

似乎找不到此库，或者在创建新实例时出现问题

---

请检查pom.xml和application.properties。

我已经使用gcloud进行了身份验证。

我使用spring引导运行这个示例：在配置spring之前，必须启用云sql管理api

在具有以下角色的凭据中创建json：

Cloud SQL > Cloud SQL Client
Cloud SQL > Cloud SQL Editor
Cloud SQL > Cloud SQL Admin

kubectl create secret generic cloudsql-instance-credentials --from-file=credentials.json=file_name.json

kubectl create secret generic cloudsql-db-credentials --from-literal=username=ethan --from-literal=password=12345678 --from-literal=dbname=clash_royale --from-literal=connectname=projectid:region:instance-name

双向连接到gcloud sql，它可以完美地工作

之后运行它，但没有该部分。请始终以

[MY\u Project\u Id]

的形式编写项目Id。这是一个敏感的私有数据。另外，请分享您的
