Error creating bean with name ‘dataSource‘ defined in class path resource [org/springframework/boot_error creating bean with name 'datasource' defined

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Failed to determine a suitable driver class

 由于yml文件命名为了bootstartup.yml,所以springboot没有检测加载，将文件名称改为application.yml就可以了

后续：

由于创建的是springCloud项目，上网查询说bootstrap 加载优先于 applicaton,建议使用bootstartup.yml，然后又进行搜索，最后发现可能是spring-cloud-dependencies依赖没有读取到

		 <!-- SpringCloud 微服务 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

将版本直接写上刷新一下，发现能够读取到bootstartup.yml

         <version>Hoxton.SR9</version>

再将版本写回版本统一管理的全局变量中，也能够正常读取
