运行我的Web应用程序时引发以下错误。

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

引发错误的说明如下，

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).

引用此答案后，我知道我必须对pom.xml文件进行一些更改。但是我不知道要更改什么，甚至StackOverflow上的类似类型问题也无法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），

请注意，在这种情况下，我不需要处理H2数据库，因此H2不是我的解决方案。
