Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
无法配置DataSource：未指定'url'属性，也无法配置嵌入数据源
解决方法一
在application.properties中配置在application.properties文件中
#数据库相关配置 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/sql_test spring.datasource.username=root spring.datasource.password=123456 spring.datasource.max-idle=10 spring.datasource.max-wait=10000 spring.datasource.min-idle=5 spring.datasource.initial-size=5
解决方法二
启动类头部声明就可以了
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
