Question

@RequestMapping(value = "/updatestatus", method = RequestMethod.POST)
    String updateRequestStatus(Principal principal, @ModelAttribute(value = "requestModel") RequestModel requestModel) {
        log.info("Updating request:");
        log.info("-------------------------------");
        Users manager = usersRepository.findOneByInitialName(principal.getName());
        RequestDO request = requestRepository.findOne(requestModel.getRequestId());
        Users employee = usersRepository.findOne(request.getUsers().getId());
        requestRepository.updateRequestStatusByRequestId(requestModel.getRequestStatus(), requestModel.getRequestId());
        // Instead of getting the same RequestDO object from DB, I just updated it's status for using in mail correctly.
        request.setStatus(requestModel.getRequestStatus());
        log.info("");
        /***
         Send Notification Mail to Employee
         ***/
        /*mailUtil.sendNotificationEmailWithTemplating(employee, manager, request);*/
        return "requests";
    }

HTML表单：

<form role="form" th:action="@{/request/updatestatus}"
   th:object="${requestModel}" method="post">
   <input type="text" th:value="${request.id}"
      th:field="*{requestId}" style="display: none;"/>
   <input type="text" th:value="APPROVED" th:field="*{requestStatus}"
      style="display: none;"/>
   <input type="hidden" th:name="${_csrf.parameterName}"
      th:value="${_csrf.token}"/>
   <input type="submit" value="Approve Request">
</form>

错误：

HTTP Status 500 - Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/requests.html]")

我正在尝试将requestId设置为当前的requestId，并将requestStatus设置为值APPROVED，但是我收到了HTTP状态500错误。我做错了什么？

从表单中请求模型：

public class RequestModel {

    private Long requestId;
    private String selectedDate;
    private RequestStatus requestStatus;

    }

    public void setSelectedDate(String selectedDate) {
        this.selectedDate = selectedDate;
    }

    public Long getRequestId() {
        return requestId;
    }

    public void setRequestId(Long requestId) {
        this.requestId = requestId;
    }

    public RequestStatus getRequestStatus() {
        return requestStatus;
    }

    public void setRequestStatus(RequestStatus requestStatus) {
        this.requestStatus = requestStatus;
    }
}

Answer 1

问题在于requestStatus属性，您应该使用控制器中相同类型的对象。例如：

控制器：

@RequestMapping(value = "/updatestatus", method = RequestMethod.GET)
public ModelAndView getRequests(){
    ModelAndView mav = new ModelAndView("requests");
    //your code
    mav.addObject("STATUS", RequestStatus.APPROVED);
    return mav;
}

在您的HTML中

<input type="text" th:value="${STATUS}" th:field="*{requestStatus}"
  style="display: none;"/>

这应该可以使它

无法从Thymeleaf表单向HTTP请求发布值
