SpringBoot-Derby运行时无法配置数据源：“url”属性未指定，无法配置嵌入式数据源

Question

我在pom下面有这个。xml文件。我在尝试运行应用程序时收到此错误消息。未能配置数据源：“url”属性未指定，无法配置嵌入式数据源。

我在谷歌上搜索过，很少有人说这个问题不应该出现在内存数据库版本中，比如H2、Derby等。然而，我遇到了这个问题。

尝试更新application.properties

#PROFILES
spring.profiles.active=dev
#JPA (JpaBaseConfiguration, HibernateJpaAutoConfiguration)
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database=default
spring.jpa.show-sql=true
#DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)
spring.datasource.continue-on-error=false
spring.datasource.generate-unique-name=false

和

spring.datasource.url=jdbc:derby:memory:local;create=true
spring.datasource.username=derbyuser
spring.datasource.password=password

但是没有喘息的机会。请让我知道我错过了什么/在哪里。

我在本地创建项目时遇到了类似的问题。使用以下方法解决了它：

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
