Spring MVC文件上傳 - 客戶端發送的請求在語法上不正確

當我嘗試訪問以下方法時，我收到（客戶端發送的請求在語法上不正確）錯誤。Spring MVC文件上傳 - 客戶端發送的請求在語法上不正確

@RequestMapping (value = "/prospect/prospectupdated", method = RequestMethod.POST) 
    public String prospectUpdated (@ModelAttribute("prospect") CustomProspectList customProspectList, @RequestParam("consentForm") MultipartFile file) throws IOException { 

     int id = customProspectList.getProsId(); 

     String consentFormStatus = prospectService.consentFormStatus(id); 

     byte[] consentFormFile = file.getBytes(); 
     String consentFormName = file.getOriginalFilename(); 
     long consentFormSize = file.getSize(); 
     String consentFormType = file.getContentType(); 

     if (consentFormStatus.equals("Y") && consentFormSize != 0){ 
      prospectService.updateConsentForm(id, consentFormName, consentFormSize, consentFormFile, consentFormType); 
     } 

     return "success"; 
    }

JSP一部分文件上傳：

<form:input path="prosConsentForm" id="consentForm" type="file" style="display:initial" name="consentForm"/>

DAO實現方法：

@Override 
    public void updateConsentForm(int id, String consentFormName, long consentFormSize, byte[] consentFormFile, String consentFormType) { 
     Session session = sessionFactory.getCurrentSession(); 
     String sql = "UPDATE ccm_prospect SET PROS_Consent_Form_Name = :ConsentFormName, PROS_Consent_Form_Size = :ConsentFormSize, PROS_Consent_Form_File = :ConsentFormFile, PROS_Consent_Form_Type = :ConsentFormType WHERE PROS_Id = :ProspectId"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.setParameter("ConsentFormName", consentFormName); 
     query.setParameter("ConsentFormSize", consentFormSize); 
     query.setParameter("ConsentFormFile", consentFormFile); 
     query.setParameter("ConsentFormType", consentFormType); 
     query.setParameter("ProspectId", id); 
     query.executeUpdate(); 
    }

幫助我在這裏：

這是customProspectList模型類。

public class CustomProspectList { 

    private int prosId; 

    private String prosDOB; 

    private String prosTrackingStatus; 

    private String prosFirstName; 

    private String prosLastName; 

    private String prosMiddleName; 

    private String prosGender; 

    private String prosEmail; 

    private String prosMobilePhone; 

    private String prosHomePhone; 

    private String prosWorkPhone; 

    private String prosCommuMethod; 

    private String prosAddrLine1; 

    private String prosAddrLine2; 

    private String prosCity; 

    private String prosState; 

    private String prosZipCode; 

    private byte[] prosConsentForm; 

    private byte[] prosHippaForm; 

    private String prosConsentFormName; 

    private String prosHippaFormName; 

    private String prosConsentFormDate; 

    private String prosHippaFormDate; 

    private BigInteger prosConsentFormSize; 

    private BigInteger prosHippaFormSize; 

    private String provNPI; 

    private String faciName; 

    private String faciAddrState; 

    private String persFirstName; 

    private String persLastName; 

    private String persMiddleName; 

    private String prosConsentFormType; 

    //getters & setters

這是形式：

<form:form commandName="prospect" action="${pageContext.request.contextPath}/prospect/prospectupdated" method="post" enctype="multipart/form-data" accept-charset="utf-8"> 
    ........ 
    </form:form>

請填寫完整的堆棧跟蹤。 –

對不起，我沒有得到控制檯中的任何堆棧跟蹤，我得到HTTP狀態400 - 只有...這個描述「客戶端發送的請求語法不正確。」 – karthi

請發佈完整的http表單以及'CustomProspectList'類，問題可能與他們有關係。順便說一句：你的表單必須具有multipart參數集，並且你需要在Spring中註冊一個註冊MultipartResolver/Filter。 https://spring.io/guides/gs/uploading-files/ – Ralph

試圖將文件綁定到：

private MultipartFile prosConsentForm;

，而不是字節數組。

如果這不起作用只需打開記錄到調試的org.springframework

對於每一個40X錯誤春天不會寫入錯誤日誌，但在調試它會克利告訴你的原因。
