Question

我分别有Spring Boot控制器和logger服务方法，通过发送请求调用控制器时，logger服务必须收集有关请求和响应的数据，并通过restemplate将其发送到外部logger服务。我想配置或找到在micorservice环境中的单元测试中使用Restemplate的解决方案

当我尝试通过邮递员向控制器发送请求时，控制器方法运行良好。它按预期运行。但是当我测试控制器本身时，restemplate的postForObject（...）方法始终返回null值。但是，这对于控制器方法是不正常的。控制器方法名称：findAllCrmDevices（）服务方法名称：log（日志日志）-如下所示

控制器方法：

 @RequestMapping(value = "/find-all-crm-devices", method = RequestMethod.GET)
    public ResponseEntity<RestApiObject> findAllCrmDevices(){
        logger.info("device_controller.find_all_devices --> pre start");

        Logs logs = new Logs();
        RestApiObject restApiObject = new RestApiObject();

        try {
            logs.setRequestBody("{}");

            List<DeviceDetails> devices = iDeviceService.findAll();

            restApiObject.setObject(devices);
            restApiObject.setCode(environment.getProperty("ok",Integer.class));
            restApiObject.setMessage(environment.getProperty("message_0"));
            restApiObject.setHostAddress(NetUtility.getLanAddress());

            logs.setResponseBody(objectMapper.writeValueAsString(restApiObject));
            logs.setResponseDate(new Date());

            loggerService.log(logs);
        } catch (RestLoggingException e){
            logger.error("Error",e);
            restApiObject.setCode(e.getCode());
            restApiObject.setMessage(e.getMessage());
        } catch (Exception e) {
            logger.error("Error",e);
            restApiObject.setCode(environment.getProperty("ex9999",Integer.class));
            restApiObject.setMessage(environment.getProperty("message_9999"));
        }finally {
            return new ResponseEntity<>(restApiObject,HttpStatus.OK);
        }
   }

服务方法：

@Override
   public void log(Logs logs)  throws RestLoggingException {
       logger.info("logger_service_impl.log() --> log: {}",logs);

       RestApiObject response = restTemplate.postForObject(saveLogUrl,logs, RestApiObject.class);

       logger.info("logger_service_impl.log() --> log service url: {}",saveLogUrl);
       logger.info("logger_service_impl.log() --> rest api object: {}",response);

       if (response.getCode() == 9999){
           logger.info("logger_service_impl.log() --> failed to log");

           throw new RestLoggingException(environment.getProperty("message_9001"),
                   environment.getProperty("ex9001",Integer.class));
       }

       logger.info("logger_service_impl.log() --> successfully logged");
   }

单元测试

@Test
    public void findAllCrmDevicesTest() throws Exception{

        mvc.perform(
                get("/api/device/find-all-crm-devices").
                        contentType(MediaType.APPLICATION_JSON_UTF8)
        )
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.code",is(0)))
                .andExpect(jsonPath("$.object",allOf(notNullValue(),not(emptyArray()))));

        // TODO: 8/20/2019
    }

当resttemplate在服务层中收到响应为null时，JUnit测试失败
