If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
具体报错信息
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
//无法配置数据库，没有指定url属性，并且无法配置embedded datasource
Reason: Failed to determine a suitable driver class
//原因：无法明确指定正确的驱动类（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).
//建议：
//如果如果需要加载嵌入式的数据库，请将他放入路径中
//如果有数据库设置需要从指定配置文件中加载，需要调用该配置文件（目前没有活动的配置文件）
Process finished with exit code 1
方法一
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
在启动类中加入
方法二
相信你能看到这上面的方法一还是没用。
那就用我自创的玄学
复制上面代码，更新maven,运行，然后应该还是报错，你把添加的这些代码去掉，在更新maven，运行就成了，亲自测试，还是两次，都成了！！！
有知道为啥的可以留言，暂定为 玄学，哈哈
有可能是没有加截到配置文件，可以尝试在pom.xml文件的build标签中加入如下内容
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
