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).
인터넷에서 많은 해결 방안을 검색하면springboot가 시작될 때 자동으로 데이터 원본을 주입하고 jpa를 설정하여 @SpringBoot Application에서 @SpringBoot Application(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})을 제거합니다.
우선 위의 이 말이 무슨 뜻인지 알아야 한다.시작할 때 자동으로 데이터 원본을 주입합니다.
많은 초보자들이 다른 사람의 프로필을 직접copy하기 때문에 프로필에 이렇게 쓰여 있습니다. 많은 사람들이 프로필 응용 프로그램에 사용합니다.properties는 이렇게 썼습니다:spring.druid.url=jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull spring.druid.username=root spring.druid.password=xxxxx spring.druid.maxActive=20 spring.druid.minIdle=3 spring.druid.maxWait=10000 spring.druid.validationQuery=SELECT ‘x’ spring.druid.timeBetweenEvictionRunsMillis=60000 spring.druid.minEvictableIdleTimeMillis=300000 spring.druid.borrowConnectionTimeout=30000
다음 코드를 추가해야 합니다:importjava.sql.SQLException;

@Configuration public class DruidConfig {

@ConfigurationProperties(prefix="spring.druid")

	DruidDataSource dataSource = new DruidDataSource();
	dataSource.setProxyFilters(Lists.newArrayList(statFilter()));
	return dataSource;
}

	StatFilter filter = new StatFilter();
	filter.setSlowSqlMillis(5000);
	filter.setLogSlowSql(true);
	filter.setMergeSql(true);

}


@Bean
