데이터베이스 유형 NONE에 대한 포함된 데이터베이스 드라이버 클래스를 결정할 수 없음에 대한 수정
보시다시피 내 Java 클래스에는 아무것도 없으므로 오류는 Spring Boot와 관련이 있습니다. 이 문제를 해결할 수 있는 두 가지 방법을 찾았습니다.
-
Exclude auto configuration of DataSource in the Spring Boot application class. We can do this using
EnableAutoConfigurationannotation as shown in below code.package com.journaldev.spring; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; @SpringBootApplication @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) public class SpringBatchHelloWorldApplication { public static void main(String[] args) { SpringApplication.run(SpringBatchHelloWorldApplication.class, args); } }With above configuration, JUnit test case executed fine and no more Cannot determine embedded database driver class for database type NONE error.
-
Another way to fix this issue is to provide
spring.datasource.urlin theapplication.propertiesfile. It worked for me, although I didn’t provided any database username and password.spring.datasource.url=jdbc:mysql://localhost/Test_DB
