mysqlデータベースを指すようにデータソースを変更するSpringBoot

@springbootapplicationとは何datasourceですか？どのようにロードしますか？datasourceデフォルトのデータベースから別のデータベースに変更するにはどうすればよいですか。プロパティファイルを追加するだけでは、mysqlまだ接続が確立されませんか？

たとえば、私はこのコードを持っています

package hello.springjpa;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
public class Application implements CommandLineRunner{

@Autowired
DataSource dataSource;

@Autowired
CustomerRepository customerRepository;

public Application() {
}

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

@Override
public void run(String... arg0) throws Exception {
    customerRepository.save(new Customer("Akib", "Juan"));
    customerRepository.save(new Customer("Jane", "Waheed"));
}


}

そして私はresources / application.propertiesファイルに以下を追加しました

# DataSource settings: set here configurations for the database connection
spring.datasource.url = jdbc:mysql://localhost:3306/employee
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver

# Specify the DBMS
spring.jpa.database = MYSQL

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate settings are prefixed with spring.jpa.hibernate.*
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy

次のエラーがスローされます
