Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. SPRING
提问by Zufra
I've already checked all the similar questions and every answer says that I need to specify a driverClassName which I already do. Here is my application.yml:
我已经检查了所有类似的问题，每个答案都说我需要指定一个我已经这样做的 driverClassName。这是我的 application.yml：
spring:
application:
name: cibus-backend
datasource:
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
username: root
password: 1234567890
jpa:
show-sql: true
hibernate:
ddl-auto: update
properties:
hibernate:
format_sql: true
type: trace
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
database: mysql
logging:
level:
org:
hibernate:
type: trace
Am I missing something? The weird thing is that a classmate of mine who has the same code can start the app perfectly well. This is why I think it has something to do with the path. Maybe spring isn't accessing the yml file. I included it in src.main.resources which is the default place where Spring looks for it. Here is the stacktrace:
我错过了什么吗？奇怪的是，我一个有相同代码的同学可以很好地启动应用程序。这就是为什么我认为它与路径有关。也许 spring 没有访问 yml 文件。我将它包含在 src.main.resources 中，这是 Spring 寻找它的默认位置。这是堆栈跟踪：

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Here is the Gradle Build as I was asked to include it:
这是 Gradle Build，因为我被要求包含它：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
Any ideas? Thank you in advance.
有任何想法吗？先感谢您。

Cannot determine embedded database error
无法确定嵌入式数据库错误
Try Excluding the auto configuration of DataSource in the Spring Boot application class. You can do this using EnableAutoConfiguration
尝试在 Spring Boot 应用程序类中排除 DataSource 的自动配置。您可以使用EnableAutoConfiguration执行此操作
