Question

当我尝试访问以下方法时，我收到（客户端发送的请求语法错误）错误。

@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";
    }

用于文件上传的JSP部分：

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

DAO实施方法：

@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();
    }

在此帮助我：

这是customProspectList模型类。

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

这是表格：

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

尝试将您的文件绑定到：

private MultipartFile prosConsentForm;

而不是字节数组。

如果这不起作用，只需将记录器转为org.springframework的调试

对于每40X错误，spring不会写错误日志，但在调试中它会清楚地告诉你原因。

Spring MVC文件上传 - 客户端发送的请求在语法上是不正确的
