【问题描述】:
我正在尝试使用 Junit 对控制器类进行单元测试。但是,当我尝试自动装配我的扩展 crudRepository 的 PlayerRepository 接口时,它给出了这个错误:
2018-12-06 21:59:39.530 错误 8780 --- [主要] o.s.test.context.TestContextManager : 捕获异常同时 允许 TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@78e117e3] 准备测试实例 [edu.ceng.gameproject.player.PlayerControllerTest@4f704591]
(因为很长,我没有把整个错误写出来。)
它还说:
原因: org.springframework.beans.factory.NoSuchBeanDefinitionException: 否 'edu.ceng.gameproject.player.PlayerRepository' 类型的合格 bean 可用:预计至少有 1 个符合 autowire 条件的 bean 候选人。依赖注解: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
顺便说一句,我可以在我的控制器中进行自动装配以对数据库进行更改。它只是在测试中不起作用。这是我的代码:
控制器类:
@Controller // This means that this class is a Controller
@RequestMapping(path="/Player") // This means URL's start with /Player
(after Application path)
public class PlayerController {
@Autowired
private PlayerRepository playerRepository;
}
这是 PlayerRepsitory 接口:
@Repository
public interface PlayerRepository extends CrudRepository<Player, String> {
}
我进行自动装配的抽象测试类:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = Main.class)
@WebAppConfiguration
public abstract class GameProjectBackEndApplicationTests {
protected MockMvc mvc;
@Autowired
WebApplicationContext webApplicationContext;
@Autowired
PlayerRepository playerRepository;
protected void setUp() {
mvc =
MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
}
我使用自动装配 playerRepository 的 PlayerControllerTest 类:
public class PlayerControllerTest extends GameProjectBackEndApplicationTests
{
@Override
@Before
public void setUp() {
super.setUp();
}
@Test
public void test_getUsersList_withOk() throws Exception {
String uri = "/Player/all";
// Create user in the database
Player createdUser = playerRepository.save(new Player("testUser",
"testPassword"));
MvcResult mvcResult = mvc.perform(MockMvcRequestBuilders.get(uri)
.accept(MediaType.APPLICATION_JSON_VALUE)).andReturn();
// check if status is 200 - OK
int status = mvcResult.getResponse().getStatus();
assertEquals(200, status);
String content = mvcResult.getResponse().getContentAsString();
Player[] playerList = super.mapFromJson(content, Player[].class);
// check if list has actually any user
assertTrue(playerList.length > 0);
// check returned list has user that we created
boolean contains = false;
for (int i = 0; i < playerList.length; i++) {
if
(createdUser.getUsername().equals(playerList[i].getUsername())
&&
createdUser.getPasswd().equals(playerList[i].getPasswd())) {
contains = true;
}
}
// assert there is a user that we created
assertTrue(contains);
//delete created user
playerRepository.deleteById(createdUser.getUsername());
}
}
提前致谢。
【问题讨论】:
-
您是否尝试在您的TestClass 上添加@DataJpaTest?
-
试过但没用。
-
使用
@MockBean注入所需的依赖项。 -
我应该如何使用@MockBean,你能更清楚一点吗?
-
相关包有哪些?如果 PlayerControllerTest 所在的包不在定义 @Controller 的包处或之上,则 Spring 的默认自动检测将找不到您的控制器。在这种情况下,您需要明确告诉 Spring 哪些包要包含在扫描中,这可以通过注释轻松完成。如果这不是问题,我有第二个想法。
