我正在使用 Spring Boot 2.0.6.RELEASE 。我的应用程序使用 Oracle jdbc驱动程序，并且在这种配置下可以很好地工作：
spring.datasource.url=jdbc:oracle:thin:@my-data-server/database
spring.datasource.username=username
spring.datasource.password=pwd
spring.datasource.hikari.maximum-pool-size=10
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
但是... 添加执行器时，应用程序无法启动。似乎/health端点导致了此问题（也许是因为它是第一个需要数据源的bean？）。
问题是数据源无法实例化...但是没有执行器就可以很好地工作。
有什么想法吗？
我想知道DataSourceHealthIndicatorAutoConfiguration 是否可能是问题的根源：此类带有注释@AutoConfigureAfter(DataSourceAutoConfiguration.class) ...但是看来光H并未使用此标记autoconfig类，对吗？我在堆栈跟踪中看到org.springframework.boot.autoconfigure.jdbc.DataSourceConfiguration$Hikari，但没有看到DataSourceAutoConfiguration ...
**更新：**我正在使用FlyWay
**更新2 **，这可能是一个提示：https://github.com/spring-projects/spring-boot/issues/14687
这是完整的堆栈跟踪：

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 (the profiles dev are currently active).
