获取 MockMvc 和 @MockBean 字段的空指针

如何解决获取 MockMvc 和 @MockBean 字段的空指针

我有一个测试类和一个通用的测试配置类，如下所示，我将配置注入到测试类中。

public class ControllerTest extends TestConfig {
  @MockBean
  private ProductListService productListService;
  private String token;

  @BeforeEach
  public void init() throws Exception {
      token = getToken();
  }


@Test
public void createProductListtest() throws Exception {

    ProductRequestDto productRequestDto = new ProductRequestDto();

    when(productListService.createProductList(productRequestDto))
            .thenAnswer(inv -> new ProductRequestDto());

    String uri = "/products-lists";
    MvcResult mvcResult = mvc.perform(mockmvcRequestBuilders.post(uri)
            .accept(MediaType.APPLICATION_JSON)
            .contentType(MediaType.APPLICATION_JSON)
            .header("Authorization",token)
            .content(requestBody(productRequestDto))
    ).andReturn();
}

TestConfig 类：

@SpringBoottest(classes = {SpringBootApplication.class,TestConfig.RestTestConfig.class},properties = {"spring.main.allow-bean-deFinition-overriding=true"})
@WebAppConfiguration
@AutoConfiguremockmvc
public class TestConfig {

  protected mockmvc mvc;
  @Autowired
  protected WebApplicationContext webApplicationContext;

  @BeforeEach
  public void setUp() {
      mvc = mockmvcBuilders.webAppContextSetup(webApplicationContext).build();
  }

  protected static String requestBody(Object request) {
    // return request string 
  }

  protected String getToken() throws Exception {
    // return token 
  }

但是在 ControllerTest 中，我收到了 productListService 和 mvc 的空指针异常。它没有正确模拟和注入吗？我哪里出错了？
