Spring Boot:无法配置DataSource:未指定'url‘属性，无法配置嵌入的数据源

当我运行我的web应用时，抛出了以下错误。
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is 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抛出的错误描述如下：
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:<br>
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
<br> If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).在引用了this answer之后，我知道我必须对我的pom.xml文件做一些修改。但是我不知道要修改什么，即使是StackOverflow上的类似类型的问题也不能帮助我解决这个问题。
我的pom.xml如下(当我创建项目时，我添加了"Web"，"JPA"，"MySQL“依赖项)，
