SpringBootTest报错Caused by: org.springframework.beans.factory.BeanCreationException: Error creating b-优快云博客

在尝试运行Spring Boot的AnimalCenterApplicationTests测试类时，遇到了一个Bean创建异常，具体表现为无法满足依赖于'sqlSessionFactory'的bean创建，进一步追踪发现错误源于'dataSource'的初始化失败，主要是因为无法确定合适的数据库驱动类。解决方法是在测试类上添加@ActiveProfiles('sit')注解，以指定Junit测试环境。

@RunWith(SpringRunner.class)
@SpringBootTest
public class AnimalCenterApplicationTests {

    @Autowired
    private IAnimalEthicalManagementService ethicalManagementService;

    @Test
    public void test(){
        ethicalManagementService.groupBacklog();
    }

}

报错如下

解决

类上加上 @ActiveProfiles("sit") ，指定Junit测试环境
