Spring Boot 测试 - 无法加载驱动程序类：org.h2.Driver

Question

我的 springBoot 应用中有这个类：

@ContextConfiguration(classes={ ApplicationTestConfig.class})
@RunWith(SpringRunner.class)
public class ServiceTest {

    @Autowired
    private RuntimeService runtimeService;

    @Autowired
    private TaskService taskService;

    @Autowired
    private HistoryService historyService;
..
}

我的应用程序属性：

spring.datasource.url=jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

我的 pom.xml：

 <dependency>
     <groupId>com.h2database</groupId>
     <artifactId>h2</artifactId>
     <version>1.4.200</version>
     <scope>test</scope>
 </dependency>

但是当我运行测试时，我得到了这个错误：

如果它对你有用，试试这个

<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
