**console报错描述：**

> Description:
> 
> Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-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).

**解决办法：**

在启动类的@SpringBootApplication加上

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

**拓展： **

> @SpringBootApplication(exclude = \{DataSourceAutoConfiguration.class\})
> 
> 该注解的作用是，排除自动注入数据源的配置（取消数据库配置），一般使用在客户端（消费者）服务中
> 
> 当前项目其实并不需要数据源。查其根源是依赖方提供的API依赖中引用了一些多余的依赖触发了该自动化配置的加载。
