Springboot使用Mybatis启动时异常:Reason: Failed to determine a suitable driver class

新建springboot+mybatis项目时，一直报下列错误

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).

然后开始排坑操作，
1.mysql数据库服务已经启动
2.也配置了datasource的一些相关属性，例如：地址值，数据库驱动，用户名，密码
3.Mybatis xml里包名和mapper接口包名也是没有问题
上面统统都是正确的的，但还是报错。然后查看application.yml配置文件文件没有被扫描，于是乎在yml中添加了如下内容，重新启动程序，正常。

    <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.yml</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.yml</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>

作为一次脑残坑记录一下吧！
