這是因為添加了數據庫組件，所以autoconfig會去讀取數據源配置，而新建的項目還沒有配置數據源，所以會導致異常出現。
解決辦法：
1. 去掉數據庫依賴
2.在啟動類的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}，排除此類的autoconfig。啟動以后就可以正常運行。
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) public class BdservoApplication { public static void main(String[] args) { SpringApplication.run(BdservoApplication.class, args); } }
