上传文件时所需的MultipartFile参数'文件'不存在

问题描述：

我正在尝试上传文件，但我正在获取Required MultipartFile parameter 'file' is not present400Bad Requestorg.springframework.web.bind.MissingServletRequestParameterException。上传文件时所需的MultipartFile参数'文件'不存在

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>

jQuery代码在这里：

$("form#uploadrecords").submit(function(){         
    var formData = new FormData($(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; 
}

它不打控制器类。我在Firebug console找到错误。

我正在使用和jboss-eap-6.4。

我的代码有什么问题。如何解决这个问题呢？

您添加了[multipartResolver]（https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/multipart/MultipartResolver.html）bean吗？ –

@Manoj Suthar：它添加的地方？在webconfig或websecurity配置？ – Durga

答

如果你正在使用@EnableAutoConfiguration那么你需要做以下为这里讨论https://github.com/spring-projects/spring-boot/issues/2958

@EnableAutoConfiguration（排除= {} MultipartAutoConfiguration.class）定义以下豆

@Bean（NAME = “multipartResolver”）public CommonsMultipartResolver commonsMultipartResolver（）{CommonsMultipartResolver resolver = new CommonsMultipartResolver（）; resolver.setMaxUploadSize（50 * 1024 * 1024）;返回解析器; }

@Bean @Order（0）public MultipartFilter multipartFilter（）{MultipartFilter multipartFilter = new MultipartFilter（）; multipartFilter.setMultipartResolverBeanName（ “multipartResolver”）;返回multipartFilter; }
