我试图运行一个简单的Junit测试，看看我的CrudRepositories是否确实在工作。

我一直得到的错误是:

无法找到@SpringBootConfiguration，您需要在测试中使用@ContextConfiguration或@SpringBootTest(classes=…) java.lang.IllegalStateException

Spring Boot不自己配置吗?

我的测试类:

@RunWith(SpringRunner.class)
@DataJpaTest
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class JpaTest {

@Autowired
private AccountRepository repository;

@After
public void clearDb(){
    repository.deleteAll();
}

 @Test
 public void createAccount(){
     long id = 12;
     Account u = new Account(id,"Tim Viz");
     repository.save(u);
      
     assertEquals(repository.findOne(id),u);
      
 }
  
  
 @Test
 public void findAccountByUsername(){
     long id = 12;
     String username = "Tim Viz";
     Account u = new Account(id,username);
     repository.save(u);
      
     assertEquals(repository.findByUsername(username),u);
      
 }
  

Spring Boot应用程序启动器:

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"domain.repositories"})
@ComponentScan(basePackages = {"controllers","domain"})
@EnableWebMvc
@PropertySources(value    {@PropertySource("classpath:application.properties")})
    @EntityScan(basePackages={"domain"})
    public class Application extends SpringBootServletInitializer {
        public static void main(String[] args) {
            ApplicationContext ctx = SpringApplication.run(Application.class, args);         
 
        }
    }

我的库:

public interface AccountRepository extends CrudRepository<Account,Long> {

    public Account findByUsername(String username);

    }
}
