我想模擬請求實體和響應以測試控制器方法上的方法，此代碼已由另一個開發人員編寫，我應該使用mockito對其進行測試。我試圖模擬請求實體值和respionse實體值，但它不起作用，當我嘗試調試時，我得到一個反射錯誤 public class InquiryController {private static final Logger log = LoggerFactory.getLogger(InquiryController.class);@Autowiredprivate InquiryProperties inquiryProperties;@Autowiredprivate InquiryService inquiryService;@AutowiredRestTemplate restTemplate;public static int count = 0;@Beanprivate 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);}

這是因為在執行 REST 調用時，實例未通過 注入。您需要在組件類中聲明 的方法，該方法在應用程序啟動期間或換句話說，在組件掃描期間進行掃描。從而可用于 .RestTemplateSpring IOCgetRestTemplaterestTemplateautowire

按照@chrylis建議將配置與控制器分離后，您可以像這樣繼續操作。
您必須嘗試模擬 RequestEntity.post 方法。請注意，它是一個靜態方法，其模擬方式與通常的公共實例方法略有不同。為此，您需要使用PowerMockito，因為Mockito不會這樣做。
在 pom 中添加依賴項，如下所示：
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>1.6.5</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>1.6.5</version>
<scope>test</scope>
</dependency>
然后用 注釋測試類，如下所示：@RunWith@PrepareForTest
@RunWith(PowerMockRunner.class)
@PrepareForTest({RequestEntity.class})
public class TestClass {
}
和模擬 post 方法，如下所示：
PowerMockito.mockStatic(RequestEntity.class); when(RequestEntity.post(any(URI.class))).thenReturn(getRequestEntityResponseBody());
private RequestEntity< CustomerInfo > getRequestEntityResponseBody(){
//code
}
更新
CustomerInfo customerInfo = new CustomerInfo();
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.set("MyResponseHeader", "MyValue");
RequestEntity<CustomerInfo> customerInfoRequestEntity = new ResponseEntity<CustomerInfo>(customerInfo, responseHeaders, HttpStatus.OK);
PowerMockito.mockStatic(RequestEntity.class);
when(RequestEntity.post(any(URI.class))).thenReturn(customerInfoRequestEntity);
