mockMvc beans在springboot 3.2.2的集成测试中始终为空

Question

在 springboot 3.2.2 的集成测试中，我的模拟存储库 bean 始终为 null 我不明白为什么我必须模拟所有依赖的 bean。有没有办法自动完成？ 有时mockMvc也为空。

我已尝试删除

@WebMvcTest(DeliveryController.class)

并使用以下内容：

@RunAs("SpringRunner.class")
@SpringBootTest
@AutoConfigureMockMvc

但徒劳。 mockMvc 始终为空。

我不想添加以下初始化代码，因为mockMvc不应该为空

@BeforeEach
void setUp() {
    this.mockMvc = MockMvcBuilders.standaloneSetup(new DeliveryController(new DeliveryServiceImpl())).build();
}

@WebMvcTest(DeliveryController.class)
public class DeliveryControllerTest {

    @Autowired
    private static MockMvc mockMvc;

    @MockBean
    private DeliveryRepository deliveryRepository; // Mocking the repository

    @MockBean
    private UserRepository userRepository; // Mocking the repository

    @Test
    public void testCreateDelivery() throws Exception {
        DeliveryEntity delivery = DeliveryEntity.builder().deliveryId(1L).description("Test package").build();

        Mockito.when(deliveryRepository.save(Mockito.any(DeliveryEntity.class))).thenReturn(delivery);

        mockMvc.perform(get("/deliveries/1").contentType(MediaType.APPLICATION_JSON).content("{\"description\": \"Test package\"}")) // Use a JSON payload that matches your Delivery object structure
                .andExpect(status().isOk());// .andExpect(content().contentTypeCompatibleWith(MediaType.APPLICATION_JSON));

        Mockito.verify(deliveryRepository, Mockito.times(1)).save(Mockito.any(DeliveryEntity.class));
    }

    // Add more test methods for other endpoints
}

如有任何帮助，我们将不胜感激。

mockMvc 不应为 null，存储库 bean 也不应为 null。

这是我在pom文件中的依赖项

Answer 1

自动装配字段不能是静态的，它们必须是实例字段。

所以改变

@Autowired
private static MockMvc mockMvc;

到

@Autowired
private MockMvc mockMvc;
