Springbootで理由の分からないエラーが発生しているのを解決したい

SpringbootでSQLログを出したいのですが、

エラーメッセージ

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'realDataSource' defined in class path resource [com/example/AppConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.activation.DataSource]: Factory method 'realDataSource' threw exception; nested exception is java.lang.ClassCastException: class com.zaxxer.hikari.HikariDataSource cannot be cast to class javax.activation.DataSource (com.zaxxer.hikari.HikariDataSource and javax.activation.DataSource are in unnamed module of loader 'app')

というエラーがコンソールに表示されてしまい、実行する事が出来ません
正しく動くように直したいです。

App.java

package com.example;

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.context.annotation.ComponentScan;
import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.jdbc.core.namedparam.SqlParameterSource;

import com.example.domain.Customer;
import com.example.service.CustomerService;

@EnableAutoConfiguration
@ComponentScan
public class App implements CommandLineRunner{
	@Autowired
	CustomerService customerService;
	
	@Autowired
	NamedParameterJdbcTemplate jdbcTemplate;
	
	@Override
	public void run(String...strings)throws Exception {
		String sql = "SELECT id, first_name, last_name From customers WHERE id = :id";
		SqlParameterSource param = new MapSqlParameterSource().addValue("id", 1);
		
		Customer result = jdbcTemplate.queryForObject(sql, param, (rs,rowNum) -> 
		new Customer(rs.getInt("id"), rs.getString("first_name"), rs.getString("last_name"))
		);
		System.out.println("result = " + result);
	}
	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
}

AppConfig.java

package com.example;



import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import net.sf.log4jdbc.Log4jdbcProxyDataSource;

import javax.activation.DataSource;

@Configuration
public class AppConfig {
	@Autowired
	DataSourceProperties datasourceProperties;
	javax.sql.DataSource datasource;
	
	@ConfigurationProperties(prefix = "spring.datasource")
	@Bean(destroyMethod = "close")
	DataSource realDataSource() {
		@SuppressWarnings("rawtypes")
		 DataSourceBuilder factory = DataSourceBuilder
				.create(this.datasourceProperties.getClassLoader())
				.url(this.datasourceProperties.getUrl())
				.username(this.datasourceProperties.getUsername())
				.password(this.datasourceProperties.getPassword());
		this.datasource = factory.build();
		return (DataSource) this.datasource;
}
	
	@Primary
	@Bean
	Log4jdbcProxyDataSource datasource() {
		return new Log4jdbcProxyDataSource(this.datasource);
	}
}
