java - 使用 Junit 5 的 RestController unsit 测试中没有名为 'entityManagerFactory' 的 bean

Question

即使我在模拟服务层类，我在 junit5 测试类中也收到“没有名为“entityManagerFactory”的可用 bean”。 我的理解是，如果服务层被模拟，它不应该寻找实际的 jpa 实现。我不明白我错过了什么。我的应用程序在 JPA 上运行良好，我在使用 @WebMvcTest 进行单元测试时遇到的唯一问题

Spring Boot应用程序类

@SpringBootApplication(
    scanBasePackages = {"com.testapp.rest.auth"})
@EnableJpaRepositories
public class SampleAuthorizationServiceApplication {

  public static void main(String[] args) {
    SpringApplication.run(SampleAuthorizationServiceApplication.class, args);
  }
}

Controller

@PostMapping(
      value = "/testRest/auth",
      consumes = MediaType.APPLICATION_JSON_VALUE,
      produces = MediaType.APPLICATION_JSON_VALUE)
  public ResponseEntity<ResObj> testValid(
      @RequestBody ReqObj reqObj, @RequestHeader HttpHeaders headerSet)
      throws SampleTechnicalException {

    ResObj response = authServ.authorize(reqObj);

    if (response.isSuccess()) {
      log.info("Request processed successfully. response : {}", response.isSuccess());
      return ResponseEntity.ok(response);
    } else {
      log.error(
          "Request couldn't be processed successfully. response : {}",
          response.isSuccess());
      return new ResponseEntity<ResObj>(response, HttpStatus.UNAUTHORIZED);
    }
  }

服务

@Service
@AllArgsConstructor
@Slf4j
public class AuthSerive {

  private SampleRepository1 sampleRepository1;

  private SampleRepository2 sampleRepository2;

  public ResObj authorize(ReqObj reqObj) throws SampleTechnicalException {


    if (reqObj == null) {
      throw new SampleTechnicalException("throw exception");
    }
    ..
    
}

Controller 测试类

@ExtendWith(SpringExtension.class)
@WebMvcTest(controllers = AuthController.class)
class AuthControllerTest {

  @MockBean AuthSerive authServ;

  @Autowired private MockMvc mockMvc;

  

  @Test
  void testAuthSample() throws Exception {
    String jsonreq =
        "{ \"field1\":\"\", \"field2\":\"x\", \"field3\":\"\", \"field4\":\"\", \"field5\":"y", \"field6\":\"z\", \"field7\":\"x\" }";
    ResObj mockResponse =
        ResObj.builder().authSuccess(true).errorMessage(null).build();

    ReqObj mockTestObj=
        ReqObj.builder().field2("x").field5("y").field6("z").field7("x").build();

    Mockito.when(authServ.authorize(mockTestObj)).thenReturn(mockResponse);

    mockMvc
        .perform(post("/api/testRest/auth").contentType("application/json").content(jsonreq))
        .andExpect(status().isOk());

     
  }

build.gradle

dependencies {

    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-web'

    developmentOnly 'org.springframework.boot:spring-boot-devtools'

    }

    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }

Answer 1

我理解这个问题是因为 @EnableJpaRepositories 与 bootapllication 类有关，它正在尝试加载它。解决方案是 bootapplication 类应该只有 @springbootapplication 注释，任何其他配置都可以使用 @configuration 注释移出到单独的配置文件。我在这里找到的 Spring @WebMvcTest with @EnableJpa* annotation
