2019-12-07 22:33:03.959 ERROR 3760 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
*************************** 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

Solution

在SpringBootApplication后加(exclude=DataSourceAutoConfiguration.class),原因是加载了数据库依赖而没有写配置文件

/**
* starter of spring boot
*/
@SpringBootApplication(exclude=DataSourceAutoConfiguration.class)
public class DemoApplication { public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
} }
