addVendorLicense:function(){
                    var self=this;
                    if(app.vendorId){

                     $('#licenseForm').ajaxSubmit({
                        url: "vendorLicense/create/"+app.vendorId,
                        async:false,
                        success: function (res) {
                            alert(res.message);
                           self.addLicenseRow();
                        },
                        error:function(res){
                            alert(res.message);
                        }
                    });
                    }
                    else{
                        alert("Please Add a vendor First");
                    }   
                    return false;
             },**

***Spring Controller***

@RequestMapping(value = "/create/{vendorId}", method = RequestMethod.POST)
    public ResponseEntity<VendorLicenseResponse> createLicense(LicenseRequest licenserequest,@PathVariable("vendorId") String vendorId) {}

***Request Object***

public class LicenseRequest extends BaseRepresentation {

@JsonIgnore

    private String licenseType;

    private String licenseName;

private String licenseNumber;

    @JsonIgnore
    private String expirationDate;

    @JsonIgnore
    private List<String> statesCovered;

    private String terms;

    private String brokerNumber;

    private String organizationId;

    @JsonIgnore
    private CommonsMultipartFile insuranceFiles;

}

我正在尝试将多部分表单数据映射到 LicenseRequest 对象。当使用文件提交表单时，会正确解析 rquest，但是当没有文件提交表单时，服务器会给出 400 错误请求错误。有人可以告诉我如何制作文件在 multipart/form-data 中是可选的。

Answer 1

您可以直接抓取它并将其设为可选，而不是将其放入请求对象中，我不确定您是否可以在自定义对象中指定可选部分。

@RequestMapping(value = "/create/{vendorId}", method = RequestMethod.POST)
public ResponseEntity<VendorLicenseResponse> createLicense(LicenseRequest licenserequest,@PathVariable("vendorId") String vendorId,
@RequestParam(value = "insuranceFiles", required = false) CommonsMultipartFile insuranceFiles) {
   if(insuranceFiles != null){}
}
