方法一：
创建一个spring boot demo，启动main方法出现如下错误
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).
Process finished with exit code 1
原因：由于创建的spring boot的时候在pom.xml上引入了mybatis包的原因，而在配置文件中没有涉及，所以之后在pom.xml上删除mybatis包的引入就行。
方法二：
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) public class BdservoApplication { public static void main(String[] args) { SpringApplication.run(BdservoApplication.class, args); } }
