在springboot启动时报错Cannot determine embedded database driver class for database type NONE解决办法

1,原因：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "dev" are currently active).

 

2，解决方案：

在你的pom依赖里加上这句就够了，重启有惊喜

<dependency>
        <groupId>com.h2database</groupId> 
        <artifactId>h2</artifactId>
        <scope>runtime</scope> 
</dependency>
