Fehler beim Konfigurieren einer DataSource: Das 'url'-Attribut wurde nicht angegeben und es konnte keine eingebettete Datenquelle konfiguriert werden. FRÜHLING
Ich habe bereits alle ähnlichen Fragen geprüft und jede Antwort besagt, dass ich einen driverClassName angeben muss, den ich bereits tue. Hier ist meine 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
Fehlt mir etwas? Das Seltsame ist, dass ein Klassenkamerad von mir, der denselben Code hat, die App perfekt starten kann. Deshalb glaube ich, dass es etwas mit dem Pfad zu tun hat. Möglicherweise greift der Frühling nicht auf die Yml-Datei zu. Ich habe es in src.main.resources aufgenommen. Dies ist der Standardort, an dem Spring danach sucht. Hier ist der Stacktrace:
Error starting ApplicationContext. To display the conditions report re-run
your application with 'debug' enabled.

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).

Irgendwelche Ideen? Danke im Voraus.
Um das zu beheben
Fehler in eingebetteter Datenbank kann nicht ermittelt werden
Versuchen Sie, die automatische Konfiguration von DataSource in der Spring Boot-Anwendungsklasse auszuschließen. Sie können dies mit EnableAutoConfiguration tun.
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class {...}
Erwähnenswert ist auch, wie das in Kotlin aussieht:
@SpringBootApplication(
exclude = [DataSourceAutoConfiguration::class]
)
class Launcher
...
... für diejenigen von uns, die kotlin schreiben, aber mit demselben Fehler hierher gekommen sind.
Ihr Yml-Dateiformat ist nicht korrekt. Ändern Sie die Startzeilen in
spring:
...
datasource:
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
username: root
password: 1234567890
Behalten Sie dieses Format der Leerzeichen in der gesamten Datei bei
Für Spring Boot mit JPA und Hibernate use Beispiel:
spring.datasource.type = com.zaxxer.hikari.HikariDataSource spring.datasource.url = jdbc: postgresql: // localhost: 5432/somedb
Sie können andere Eigenschaften in Link überprüfen
Die Lösung, die für mich funktioniert hat, ist die folgende
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);
}
}
