现场情景：

初次搭建springboot工程，原本要搭建一个springboot+mybatis的maven工程，听说springboot会把一切给配置好，天真的在执行完mybatis自动生成mapper文件后进行打包，当前springboot工程只有一个空的application.properties文件，没有进行任何配置，故进行打包时（执行run as maven install命令）报以下错误：

观察错误意为有数据源的依赖包但没有配置数据源：

添加两个配置文件（个人偏好使用yml文件，故删掉类application.properties文件添加了yml文件进行配置）：

application.yml：

spring:profiles:active: dev

application-dev.yml：

server:port: 8080spring:datasource:username: rootpassword: wbj@1992*url: jdbc:mysql://localhost:3306/swyx_form?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTCdriver-class-name: com.mysql.jdbc.Drivermybatis:mapper-locations: classpath:mapping/*Mapper.xmltype-aliases-package: com.example.entity#showSql
logging:level:com:example:mapper : debug

重新执行打包命令，再无异常
