java - Spring boot Bean异常: Cannot determine embedded database driver class for database type NONE

Question

我正在尝试运行由其他人制作的 Spring Boot 应用程序。我尝试将本地数据库附加到应用程序，但是当我运行它时，它给出以下错误；

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

我是新手，我无法找出问题所在。一些细节:

其中 xxx = 数据库名称。

工作台:

Name: Local instance wampmysqld64
Host: localhost
Port: 3306
Server: MySQL Community Server (GPL)
Version: 5.7.18-log
Connector: C++ 1.1.4 
Login User: root
Current User: root@localhost

服务器已启动并正在运行。

package com.fyakuthibernatespringboot.demo;


@SpringBootApplication
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}
