Spring mvc org.springframework.web.multipart.MultipartException：当前请求不是多部分请求

我正试图向服务器发送一个多部分请求，但遇到以下异常 HTTP状态500-请求处理失败；嵌套异常为org.springframework.web.multipart.MultipartException：当前请求不是多部分请求

<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-body">
        <form id="imageuploadForm" action="<c:url value="/members/profileimageupload" />" method="POST" enctype="multipart/form-data">
            <div style="width:40%; float:left">
                <div class="fileupload fileupload-new" data-provides="fileupload">
                    <div class="fileupload-preview thumbnail" style="width: 200px; height: 150px;"></div>
                    <div>
                        <span class="btn btn-file">
                            <span class="fileupload-new">Select image</span>
                            <span class="fileupload-exists">Change</span>
                            <input id="imageFile" name="imageFile" type="file" />
                        </span>
                        <a href="#" class="btn fileupload-exists" data-dismiss="fileupload">Remove</a>
                    </div>
                </div>
            </div>
            <div style="width:40%; float:right" >
                <div class="progress">
                    <div class="bar" style="width: 60%;"></div>
                </div>
            </div>
        </form>
    </div>
    <div class="modal-footer">
       <button class="btn btn-success" id="submit">Upload</button>
       <button class="btn btn-primary" data-dismiss="modal" aria-hidden="true" >Close</button>
    </div>
 </div>

我的控制器应该处理请求

@RequestMapping(value="/profileimageupload",method= RequestMethod.POST)
    public void uploadProfileImage(@RequestParam(value="imageFile") final MultipartFile file) throws NumberFormatException, IOException{
    ////
}            

我有以下多部分文件的web配置

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    /**
    * Supports FileUploads.
    */
    @Bean
    public MultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setMaxUploadSize(500000000);
        return multipartResolver;
    }
}

似乎您的标签表单的格式不好，并且

'action="<c:url value="/members/profileimageupload" />"' 

'action=”“'

正在被忽视。 试着这样写，看看它是否有效：

action="<c:url value='/members/profileimageupload' />"

action=“”

请使用“标题”重试：

下面是ajax调用：

我希望这对你有帮助

检查您是否在Spring-Servlet.xml中添加了CommonMultipartResolver

依赖关系

commons-fileupload.jar

commons-io.jar

我发现“POST”部分很重要，它不能处理GET请求。

action="<c:url value='/members/profileimageupload' />"

@RequestMapping(value = "/profileimageupload", headers = "content-type=multipart/*", method = RequestMethod.POST)

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

<form id="fileupload" method="post" enctype="multipart/form-data">

 @RequestMapping(value = "/profileimageupload", method = RequestMethod.POST)
public ModelAndView uploadProfileImage(MultipartHttpServletRequest request) {}
