spring-boot - Junit 5 集成测试中的 @SpringBootTest 有 UnsatisfiedDependencyException
问题描述
控制器：
@RestController
public class UserController {
@Autowired
public UserService svc;
...
}
服务：
@Service
public class UserService {
@Autowired
private UserDao dao;
...
}
Dao 是一个简单的存储库接口。
测试：
@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = {UserController.class, UserService.class, UserDao.class})
public class UserIntegrationTest {
@Autowired
private UserController controller;
@Test
public void createUserTest() {
User integration = new User();
integration.setName("integration");
integration.setEmail("initial@integration.com");
integration.setRoles(new ArrayList<String>());
Response response = controller.addUser(integration.getName(), integration.getEmail(), integration.getRoles());
Assertions.assertEquals(200, response.getStatus());
}
}
错误输出：

如果我直接运行主应用程序，一切都很好。但我不能做测试。
正如其他线程所说，我已经在 @SpringBootTest 中添加了所有 bean 类，但它不能解决问题。有没有人知道原因和解决方案？
解决方案
您应该直接使用@SpringBootTest或在@SpringBootTest(classes={Your-Starter-Application-Class})中指向您的 {your-starter-application-class} ，删除控制器、服务和 dao，因为注释中的类SpringBootTest 用于加载 ApplicationContext，如果未定义显式类，则测试将查找嵌套的@Configuration类
@SpringBootTest
或者
@SpringBootTest(classes = {Your-Starter-Application-Class})
