我正在使用Spring Boot，Hibernate和My sql，但出现错误。

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“
org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration”的bean时出错：通过构造函数参数0表示的不满意依赖关系；嵌套异常是org.springframework.beans.factory.BeanCreationException：创建在类路径资源[org
/ springframework / boot / autoconfigure / jdbc / DataSourceConfiguration $
Hikari.class]中定义的名称为“ dataSource”的bean时出错：通过工厂方法进行Bean实例化失败;
嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.zaxxer.hikari.HikariDataSource]：工厂方法’dataSource’引发了异常；嵌套异常是java.lang.IllegalStateException：无法在组织上加载驱动程序类：com.mysql.jdbc.Driver。嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.zaxxer.hikari.HikariDataSource]：工厂方法’dataSource’引发了异常；嵌套的异常是java.lang.IllegalStateException：无法在org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod（ConstructorResolver.java:590）〜[spring-

@Entity
