写项目的时候遇到报错信息

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).

刚开始看到这个错误的时候，是想着去配置一下数据源指定下mysql的地址一类的，后来一想自己的这个子项目不需要使用数据库。但是因为引入了其他一些依赖所以需要排除下数据源，找到我们的启动类在@springbootApplication上加入属性

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})

最终解决问题。
