SpringBoot配置报错：Description: Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. Reason: Failed to determine a suitable driver class

 

报错：

　　Description:

　　Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

　　Reason: Failed to determine a suitable driver class

 

　　Action:

　　Consider the following:
　　If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
　　If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

　　

 

原因：

　　SpringBoot默认会加载org. springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration类；
　　DataSourceAutoConfiguration类使用了@Configuration注解向spring注入了dataSource bean；

　　因为工程中没有关于dataSource相关的配置信息，当Spring创建dataSource bean因缺少相关的信息就会报错。

 

解决：

　　在启动类注解后加上： @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

　　若不提示导包，可直接copy：

　　import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
　　import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;

 

　　再次启动即可。
