java.lang.IllegalStateException：无法加载ApplicationContext Spring Boot + JUnit测试

时间：2018-08-23 20:05:44

标签： spring-boot jpa junit

我已经用JPA Hibernate开发了SpringBoot应用程序，并且运行良好。现在我必须从测试开始，老实说我不知道​​如何解决这个错误：

APPLICATION FAILED TO START

Description:
    Field playersRepository in model.RestService required a bean of type 'model.PlayersRepository' that could not be found.
Action:

Consider defining a bean of type 'model.PlayersRepository' in your configuration.

我有这个课程要测试：

package testing;

import model.*;
import static org.junit.Assert.assertTrue;


@RunWith(SpringRunner.class)
@SpringBootTest(classes=RestService.class)
public class ApplicationTestSuite {
@Autowired 
RestService restService;
private static Date start, end;
private static CTF ctf;


@BeforeClass
public static void setup() {
    start=new Date();
    end= new Date();
    end.UTC(2018, 9, 21, 10, 00, 00);
    ctf= new CTF("CTF test", start, end, null);
}



@Test
public void Ninstance() {

    restService.saveCTF(ctf);
    assertTrue(restService.getCtf().getName() == "CTF test");

}
}

我正在尝试测试RestService，即：

@RestController
public class RestService {

@Autowired
private PlayersRepository playersRepository;
//and other repositories

//methods that use repositories
}

我的Players存储库是：

@Repository
public interface PlayersRepository extends CrudRepository<Player, Long> {

List<Player> findAll();
//and other methods
}

我见过this answer，但没有找到解决方案。我应该更改或添加什么？以前从未使用过这种东西，请保持友善。

答案 0 :(得分：0)

在测试类中，您将Application上下文限制为特定的Service类：

@SpringBootTest(classes=RestService.class)

因此您的存储库组件不会在Spring容器中加载和添加。
要执行集成测试，您可以将Spring Boot应用程序类指定为Application上下文。
不，这是默认行为，因为未指定任何内容（因此仅@SpringBootTest），并且单元测试类的包相同或在应用程序的Spring Boot测试类的包内。
