java - 模拟请求实体调用以进行单元测试

Question

我想模拟请求实体和响应以测试 Controller 方法上的方法，此代码是由另一位开发人员编写的，我应该使用mockito来测试它。我正在模拟 Controller 类

我正在尝试模拟请求实体值和响应实体值，但它不起作用，并且在尝试调试时遇到反射错误

    public class InquiryController {

private static final Logger log = 
    LoggerFactory.getLogger(InquiryController.class);

@Autowired
private InquiryProperties inquiryProperties;

@Autowired
private InquiryService inquiryService;


@Autowired
RestTemplate restTemplate;

public static int count = 0;


@Bean
private RestTemplate getRestTemplate() {
    return new RestTemplate();
}

    @PostMapping(value = "/endCustomer", produces = { MediaType.APPLICATION_JSON_VALUE }, consumes = {
        MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<List<EndCustomerDTO>> endCustomer(@RequestBody CustomerInfo customerInfo)
        throws IOException, JSONException {

    log.info("### InquiryController.endCustomer() ===>");
    List<EndCustomerDTO> endCustomerDTOs = null;

    try {

        //RestTemplate restTemplate = new RestTemplate();
        RequestEntity<CustomerInfo> body = RequestEntity.post(new URI(inquiryProperties.getEndCustomer()))
                .accept(MediaType.APPLICATION_JSON).body(customerInfo);
        ResponseEntity<List<EndCustomerDTO>> response = restTemplate.exchange(body,
                new ParameterizedTypeReference<List<EndCustomerDTO>>() {
                });
        endCustomerDTOs = (response != null ? response.getBody() : new ArrayList<EndCustomerDTO>());

    } catch (RestClientException | URISyntaxException e) {
        log.error("InquiryController.endCustomer()" + e.getMessage());
    }

    log.info("### END InquiryController.endCustomer()  ===>");

    if (null == endCustomerDTOs) {
        return new ResponseEntity<List<EndCustomerDTO>>(new ArrayList<EndCustomerDTO>(), HttpStatus.OK);
    }
    return new ResponseEntity<List<EndCustomerDTO>>(endCustomerDTOs, HttpStatus.OK);

}

Answer 1

这是因为在执行 REST 调用时，未通过 Spring IOC 注入(inject) RestTemplate 实例。您需要在应用程序启动期间(即组件扫描期间)扫描的组件类中声明 getRestTemplate 方法。从而使 restTemplate 可用于 autowire。
