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已经执行的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
我想念什么吗?奇怪的是,我的一个拥有相同代码的同学可以很好地启动该应用程序。这就是为什么我认为它与路径有关。也许spring不能访问yml文件。我将它包含在src.main.resources中,这是Spring查找它的默认位置。 这是堆栈跟踪:

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).

有什么想法吗?预先谢谢你。
答案 0 :(得分:3)
要修复
无法确定嵌入式数据库错误
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
完成此操作@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class {...}
答案 1 :(得分:0)
值得一提的是Kotlin的外观:
@SpringBootApplication(
exclude = [DataSourceAutoConfiguration::class]
)
class Launcher
...
...对于那些写kotlin但又出现相同错误的人。
答案 2 :(得分:0)
对我有用的解决方案如下
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);
}
}
答案 3 :(得分:0)
你需要在spring boot中为jdbc开启autoconfig
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
添加这些行并导入下面的库
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
这很好用。
答案 4 :(得分:0)
添加以下注释对我有用:
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
