Spring Boot i baza H2

Question

Witam. W jaki sposób mogę naprawić ten błąd?:

***************************
APPLICATION FAILED TO START
***************************

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).

Moje IDE to Visual Studio Code.

Dopatrzyłem się linijki, która mówi, że maksymalna długość nazwy jest ustawiona na 25, a jedna z nazw jest długa na 27 liter. Starczyło to zmienić. Wielkie dzięki.

Answer 1

Skonfigurowałeś plik resources? 
tam powinieneś ustawić coś np. takiego w zależności od tego jak się łączysz 
 

spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

 

wyraźnie nie jest ustawiony parametr url- datasource, lub jest źle skonfigurowany? Jak wygląda u Ciebie plik properties w resources?

Teraz ten błąd się nie pojawia. Nic nie napisali w książce o modyfikacji pliku application.properties. Teraz wyskakuje mi dość długi błąd:
