Spring MVC 模拟错误

Question

我想使用spring mvc test 进行单元测试，但是出现以下错误，有人帮忙吗？

Java.lang.NoSuchMethodError: org.springframework.beans.factory.support.RootBeanDefinition.setTargetType(Lorg/springframework/core/ResolvableType;)V

另一个问题，如何将模拟对象注入 bean。

public class WebAPIController {
        @Autowired
    private HttpServletRequest request;
    @Autowired
    private NotifyTaskService notifyTaskService;
  .......
}

public class WebAPIControllerTest {
     @Mock
    private NotifyTaskService notifyTaskService;

     @Autowired
    private WebAPIController webAPIController;
..........
}

如何将'notifyTaskService'注入'webAPIController'？

如果您使用 spring-boot-starter-test，请阅读以下指南： Testing Web Layer with Spring Boot Test

我更喜欢最后一个使用@WebMvcTest 的示例，在这里您可以使用@MockBean 模拟您的NotifyTaskService。
