程序报错：

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).

错误分析： 

由于我们在新建项目的时候，勾选了 Mysql Driver这个选项

这就导致我们在pom.xml文件中，自动生成了sql相关的代码文件，但是我们在刚开始运行时，我们并没有使用sql，这里就会报错啦！

解决办法：

在Java文件中的@SpringBootApplication后面加上(exclude = DataSourceAutoConfiguration.class)

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class Springboot01Application {

	public static void main(String[] args) {
		SpringApplication.run(Springboot01Application.class, args);
	}

}

这一句就好啦，这一句的意思是“忽略数据库相关配置信息”就可以啦
