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)
解决方法：启动项修改注解：
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})此注解的意思是排除自动注入数据源的配置（也就是取消数据库配置），一般用于客户端（不需要数据源，数据源通过服务端的Restful接口提供）
