HttpServerErrorException $ InternalServerError

Question

这是我的控制器类

@PostMapping(path = "/appformsubmission")
public ChanelResponse<AppFormSubmissionResponse> saveAppForm(
        @RequestBody ChanelRequest<AppFormDetails> requestObject) throws JsonProcessingException {

    logger.info("MwController -saveAppForm ");
    if (logger.isDebugEnabled()) {
        logger.debug("Entering MwController() method");
        logger.debug("requestObject : {}", Utility.toJsonString(requestObject));
    }
    return appFormService.submitApplicationForm(requestObject);
}

服务等级

public ChanelResponse<AppFormSubmissionResponse> submitApplicationForm(ChanelRequest<AppFormDetails> request) throws JsonProcessingException{
    AppFormDetails appFormDetails = new ObjectMapper().convertValue(request.getPayload().getDataEntity().get(0), AppFormDetails.class);
    HttpEntity<?> httpEntity = new HttpEntity<>(appFormDetails);
    String submitApplicationUrl = env.getProperty("bo.appformsubmission.url")+env.getProperty("bo.appformsubmission.path");
    String applicationFormDetails =new ObjectMapper().writerWithDefaultPrettyPrinter().writeValueAsString(appFormDetails);
    logger.info("Request To BO ->{}" , applicationFormDetails);

    AppFormSubmissionBOResponse appFormSubmissionBOResponse=apiCallImpl.invokeSubmitApplicationForm(submitApplicationUrl, httpEntity);

    String appFormSubBOResponse=  new ObjectMapper().writerWithDefaultPrettyPrinter().writeValueAsString(appFormSubmissionBOResponse);
    logger.info("Response from BO {}" ,  appFormSubBOResponse);
    Status status = new Status();
    AppFormSubmissionResponse appFormSubmissionResponse = new AppFormSubmissionResponse();
    appFormSubmissionResponse.setApplicationNumber(appFormSubmissionBOResponse.getApplicationNumber());
    appFormSubmissionResponse.setPdfUrl(appFormSubmissionBOResponse.getPdfUrl());
    Payload<AppFormSubmissionResponse> appFormPayload = new Payload<>();
    List<AppFormSubmissionResponse> dataEntityList = new ArrayList<>();
    dataEntityList.add(appFormSubmissionResponse);
    appFormPayload.setDataEntity(dataEntityList );

    status.setCode(appFormSubmissionBOResponse.getStatus());
    status.setServerStatusCd("SUCCESS");
    Severity severity =new Severity();
    severity.setCDE("CodeDescVO_1.0.0");
    severity.setDSC("INFO");
    severity.setVer("Info");

    status.setSeverity(severity);
    status.setVer("StatusVO_1.0.0");

    ChanelResponse<AppFormSubmissionResponse> responseObject = new ChanelResponse<>();
    responseObject.setPayload(appFormPayload);
    responseObject.setStatus(status);

    return responseObject;
}

这是我的测试用例

@Test
public void appFormSubmissionTest() throws Exception {
    AppFormSubmissionBOResponse response = new ObjectMapper().readValue(
    AppFormSubmissionBOResponse.class.getResourceAsStream("/appFormSubmission_BO_Resp.json"),
    new TypeReference<AppFormSubmissionBOResponse>() {  });
    ChanelRequest<AppFormDetails> appForm = new ObjectMapper()
    .readValue(ChanelRequest.class.getResourceAsStream("/appFormSubmissionChanelRequest.json"),
    new TypeReference<ChanelRequest<AppFormDetails>>() {});
    Mockito.when(apiCallImpl.invokeSubmitApplicationForm(any(String.class), any(HttpEntity.class))).thenReturn(response);

    mockMvc.perform(MockMvcRequestBuilders.post("/appformsubmission").accept(MediaType.APPLICATION_JSON_UTF8_VALUE)
    .content(new ObjectMapper()
    .writeValueAsString(appForm)).contentType(MediaType.APPLICATION_JSON)).andExpect(status().isOk());


}

我遇到了错误。 org.springframework.web.util.NestedServletException：请求处理失败；嵌套的异常是org.springframework.web.client.HttpServerErrorException $ InternalServerError：500内部服务器错误

有什么建议吗？
