启动项目后报：Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured. 异常。详细异常如下所示：

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

我这里使用 druid-spring-boot-starter 来进行整合，因为 SpringBoot 最提倡的做法就是引用 starter。

例如：

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>druid-spring-boot-starter</artifactId>
   <version>1.1.10</version>
</dependency>

完整的如下：

</project>

第二步 application.yml

spring:
  datasource:
    name: druid
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      driver-class-name: com.mysql.jdbc.Driver
      filters: stat
      password: 123456
      url: jdbc:mysql://127.0.0.1:3306/ugaoxin_db?useUnicode=true&characterEncoding=UTF-8
      username: root
server:
  port: 8082

ps“
”网上的解决方案是错误的，例如：@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class }
这种无法使用数据库进行接下来的操作
