If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

1.application.properties中指定 datasource.url


spring.datasource.name=miaosha
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/miaosha
spring.datasource.username=lizhch
spring.datasource.password=lizhch

2.pom中引入 mysql的驱动

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.41</version>
</dependency>
