[Java知识库]Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource could

场景：
使用阿里云OSS服务，使用springboot进行整合，启动报错，完整信息：

***************************
APPLICATION FAILED TO START
***************************

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).

Disconnected from the target VM, address: '127.0.0.1:61811', transport: 'socket'

Process finished with exit code 1

原因：未找到数据库配置，但是使用OSS对象存储服务本身不需要配置我们的database，springboot加载时会自动加载DataSourceAutoConfiguration配置类，找不到所以报错。

解决办法:
启动类的springboot启动注解中添加exclude = DataSourceAutoConfiguration.class排除这个类的自动加载

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@ComponentScan(basePackages = {"com.zengchuiyu"})
public class OssApplication {

    public static void main(String[] args) {

        SpringApplication.run(OssApplication.class,args);

    }

}
