无法使用Spring Cloud GCP Starter将Spring Boot与Cloud SQL连接

Spring Boot新手试图将我的应用托管在第二代Cloud SQL（mysql）的GCP AppEngine Flexible上。

使用从这里获得的Spring Cloud GCP启动程序： https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-samples/spring-cloud-gcp-sql-sample，我正在尝试让我的本地spring boot应用程序连接到Cloud SQL。尝试在本地Tomcat上运行SQLApplication时，我得到：

我对此项目所做的唯一更改是对application.properties的更改。我也已经使用gcloud进行了身份验证。

这是我的application.properties，不起作用：

spring.cloud.gcp.sql.database-name=sqldemo
spring.cloud.gcp.sql.instance-connection-name=Project:Region:Instance
spring.datasource.continue-on-error=true
spring.datasource.initialization-mode=always
spring.datasource.username=myuser
spring.datasource.password=mypass

我尝试将mysql套接字工厂直接添加到pom.xml中，但是没有用：

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

我已确保启用了我的SQL API。 谢谢！

和application.properties：

spring.cloud.gcp.sql.instance-connection-name=[your-server-name]
spring.cloud.gcp.sql.database-name=[your-database-name]

# So app starts despite "table already exists" errors.
spring.datasource.continue-on-error=true

# Enforces database initialization
spring.datasource.initialization-mode=always

# Leave empty for root, uncomment and fill out if you specified a user
spring.datasource.username=root

## Uncomment if root password is specified
spring.datasource.password=root

server.port = 80

我已经使用gcloud进行了身份验证。 我正在使用spring-boot：run

运行此示例

答案 1 :(得分：0)

我认为您应该设置代理

请参见https://cloud.google.com/sql/docs/mysql/sql-proxy

答案 2 :(得分：0)

您不需要设置Cloud SQL代理。 正如您在documentation中看到的：

  

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

使用App Engine Java，Cloud SQL Socket Factory在后台进行jdbc连接，而没有任何IP地址，仅是实例名称。

似乎未找到该库，或者在创建新实例时出现问题。

请使用pom.xml和application.properties检查this gist。

答案 3 :(得分：0)

在配置Spring之前，您必须启用cloud sql admin api

以角色身份创建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

两种连接到gcloud sql的方法，效果很好

  1. 云SQL代理

配置文件deployment.yaml 

apiVersion: extensions/v1beta1
kind: Deployment

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
