Java 上载文件时，所需的MultipartFile参数“file”不存在

我正在尝试上载文件，但获得的是所需的MultipartFile参数“file”不存在400错误请求org.springframework.web.bind.MissingServletRequestParameterException

我的代码在这里：

<form id="uploadrecords" method="post" enctype="multipart/form-data">                     
 <div class="col-md-12">
 <div class="form-group" style="margin-top: 11px !important;">
 <label for="uploadfile" class="col-md-4 control-label"><span class="mandatory"></span>File to upload:</label>
 <div class="col-md-6">
 <input type="file" class="filestyle" data-buttonName="btn-primary" name="file" id="upload" accept="*"/>
 </div>
 </div>
 <div class="form-actions" style="margin-top: 51px;margin-left: 358px;">
 <button type="submit"  class="btn btn-success" style="padding: 6px 12px;"   id="upload" ><i class="fa fa-cloud-upload"></i> Upload</button>
 <button type="button"  class="btn btn-danger"  style="padding: 6px 12px;" id="cancel"  ><i class="fa fa-ban"></i> Cancel</button> 
 </div>
 </div>
</form>

$("form#uploadrecords").submit(function(){                                  
    var formData = new FormData($(this)[0]);                                    
    $.ajax({
    url : '/uploadfile', 
    type: 'POST',
    data: formData,
    async: false,
    beforeSend: beforeSendHandler,
    success: function (data) {
    var msg=data.msg;
    var obj=data.obj;   
    if(obj != 0){
    $("#countfail").html(obj);
    $("#download-modal").modal('show');
    }else{
    bootbox.alert(msg);
    }
    },
    cache: false,
    contentType: false,
    processData: false
    });
});

Java代码：

@RequestMapping(value = "/uploadfile", headers = "Content-Type=multipart/form-data", method = RequestMethod.POST)
public @ResponseBody StatusResponse upload( @RequestParam(value = "file") MultipartFile file, HttpServletRequest request,
        HttpServletResponse response) throws IOException, NoSuchFieldException, SecurityException, ParseException {
    StatusResponse sr = new StatusResponse();
    System.out.println("filename::::" + file.getOriginalFilename());
    //my logic here
    return sr;
}

它没有击中控制器类。我在Firebug控制台中发现错误

我使用的是spring boot和jboss-eap-6.4

我的代码有什么问题。如何解决此问题？

如果使用@EnableAutoConfiguration，则需要按照此处讨论的内容执行以下操作

@EnableAutoConfigurationexclude={MultipartAutoConfiguration.class} 定义以下bean

@Beanname=multipartResolver public commons multipartResolver commons multipartResolver{commons multipartResolver resolver=new commons multipartResolver；resolver.setMaxUploadSize50*1024*1024；返回resolver；}

---

@Bean@Order0 public MultipartFilter MultipartFilter{MultipartFilter MultipartFilter=new MultipartFilter；MultipartFilter.setmultipartresolverbeannamemultippartresolver；return MultipartFilter；}

您添加了Bean吗？@Manoj Suthar:添加到哪里？在webconfig或websecurity配置中？
