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：
2018-07-28 20:57:35.663 INFO 66641 --- [ main] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Starting...
2018-07-28 20:57:36.730 ERROR 66641 --- [ main] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Exception during pool initialization.

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
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
