Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-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).

如果使用@SpringBootApplication注解的方式会报上面的错误。
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
}
}解决方法1：换注解方式
@ComponentScan("com.znv")
@EnableAutoConfiguration()
@EnableScheduling
//@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
}
}
解决方法2：排除数据源类
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
}
}运行成功
