Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource
报错信息如下：
Description:
描述：
Failed to configure a Datasource:' url' attribute is not specified and no embedded datasource could be configured.
未能配置Datasource：“URL”属性未指定，也无法配置嵌入式数据源。
Reason: Failed to determine a suitable driver class
原因：未能确定合适的驱动程序类
由上可知，当你项目需要自定义数据源的时候，或者不想系统自动注入数据源的时候，就把它排除掉。
在主启动类的注解中加上
exclude = DataSourceAutoConfiguration.class
