NUnit 5 Spring MVC测试子模块中Autowired依赖的NoSuchBeanDefinitionException

Question

测试类是这样设置的：

@SpringBootTest
public class MyServiceTests {

  @Autowired
  QueryService service;

  @Autowired
  private DSLContext dsl;

  @Test
  public void TestDoSomething() throws Exception {
    service.selectBusinessEntityRelatedByBusinessEntity("C00001234", mockAuth);
  }
}

此模块中的测试运行正确。从application.yaml读取配置，autowire将真实服务或模拟注入到我的QueryService和本地DSL中。

API服务则是另一回事。如果我在没有MVC的情况下使用@SpringBootTest注释，我可以成功地让测试注入一个本地DSLContext，并使用来自application.yaml的配置。类似于以下内容的测试设置：

@SpringBootTest
public class CustomersControllerTests {

  @Autowired
  private Gson gson;

  @Autowired
  DSLContext dsl;

  @Test
  public void addCustomerTest() {
  }

@WebMvcTest
public class CustomersControllerTests {

  @Autowired
  private MockMvc mockMvc;

  @Autowired
  private Gson gson;

  private static final String testSub = "329e6764-3809-4e47-ac48-a52881045787";

  @Test
  public void addCustomerTest() {

    var newCustomer = new Customer().firstName("John").lastName("Doe");
    mockMvc.perform(post("/customers").content(gson.toJson(newCustomer)).contentType(MediaType.APPLICATION_JSON)
        .with(jwt().jwt(jwt -> jwt.claim("sub", testSub)))).andExpect(status().isNotImplemented());
  }

那么，为什么在使用MVC测试设置时找不到DSLContext呢？

Answer 1

这可能是因为@webmvctest完全禁用了Spring boot的自动配置，只扫描@controllers和其他一些select类，这些类是MVC测试所需要的..

Spring文档建议在您的情况下这样做：

如果您希望加载完整的应用程序配置并使用MockMVC，您应该考虑将@SpringBootTest与@AutoConfiguRemockMVC结合使用，而不是使用这个注释。
