springboot+maven dynamic-datasource 动态切换数据源，启动报错

Question

遇到问题
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).

Answer 1

已解决，
解决方法：启动类@SpringBootApplication(exclude= {DruidDataSourceAutoConfigure.class}),注意是DruidDataSourceAutoConfigure，不是DataSourceAutoConfiguration.class

Answer 2

看错误信息应该是你的properties配置文件中没有配置数据源吧
spring.datasource.dynamic.datasource.master.url

Answer 3

看你都发了无数次了，做一次好人吧，拿去自己改一下数据源的配置就行了
