Error log

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); }}
