Spring Boot报错：没有配置数据源（url属性未设置），进行解决。

问题

Spring Boot报错：

ERROR 2024-08-28 17:24:43.734 [main] - 

***************************
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 (the profiles default are currently active).	

解决

具体原因，项目调用FeignClient数据源，因此不需要配置数据源，在主应用里关闭数据源的设置。将注@SpringBootApplication修改如下：

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })

以上，问题解决。
