Failed to determine a suitable driver class
项目场景：
微服务项目中，多个项目互相调用时，出现
Failed to configure a DataSource: url attribute is not specified and no embedded datasource could be configured. //无法配置数据库，没有指定url属性，并且无法配置embedded datasource Reason: Failed to determine a suitable driver class //原因：无法明确指定正确的驱动类（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).
问题描述
程序启动失败，缺乏合适的启动项
解决方案：
pom文件中依赖冲突，当前类有自己的启动类，application.yml文件。但是pom中引入的类也有自己的启动类和配置文件。 所以要注意依赖里只可引入工具类或实体类，避免冲突。
