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),

请注意,在这种情况下,我不需要处理H2数据库,所以H2对我来说不是一个解决方案。
